Five Common Macro Photography Mistakes and How to Fix Them
Macro photography requires a unique set of skills, but along with these skills comes a new set of mistakes to overcome. Fortunately, many of these macro photography mistakes are easily fixed.
In this article, I discuss five common mistakes made in macro photography. Then I give you the tools to correct them in the field, which will result in instantly better macro images.
1. Shooting in direct midday sunlight
The first mistake often made in macro photography is heading out when the sun is high in the sky (midday). While the light during this time is bright, it’s also very harsh and contrasty. Images taken at this time are difficult to expose well, and colors are far less saturated.
The angle of the sun causes additional problems. It beats directly down on your subject, causing the underside to become shadowy.
I try to avoid going out to shoot on sunny afternoons. This tulip image was taken on a cloudy spring day.
How can this problem be fixed?
You have a few options. First, try waiting until the evening, when the light is warm and soft. This will reduce contrast and light your subject more evenly. You could also cast a shadow on the subject yourself, or find a subject in the shade. This will reduce the extent to which your subject encounters the harsh and contrasty light.
These tulips were photographed in the evening, when the light was far less harsh.
Cloudy days are the third option. Then, the sky acts like a huge softbox, and the light is diffused across the subject.
Another photograph on a cloudy day: notice the soft, delicate feeling and more saturated colors.
If you do decide to go out in midday, you might consider bringing a flash or a reflector to add some punch to your images and reduce midday shadows. While this won’t negate the problems described above, it will reduce them.
2. Shooting dying or dirty subjects
A second common mistake made in macro photography is shooting subjects that are either dying or dirty.
This isn’t really a problem with insect photography, but when photographing flowers, the condition of your subject is something to watch out for. If the edges of a flower are turning brown, I generally wouldn’t photograph it. Same thing if the center has some fraying stamens.
I searched through a number of dahlias until I found one in peak condition.
Flowers can also become dirty, especially if they are low to the ground. A few small pieces of dirt isn’t much to be worried about—it’s nothing that cloning can’t take care of—but too much dirt, and it becomes difficult to get a strong image.
How can this problem be fixed?
The first method just involves inspecting your subject carefully before shooting. If the flower is dying or dirty, find a different flower. You might also consider wiping away small pieces of dirt with your finger or shirtsleeve.
Checking the center of flowers is important; it’s easy to miss anthers that are on their way out. Fortunately, this rose allowed for a few images.
The second method is more difficult and involves hiding the dying parts of the flower through creative compositions. For instance, you can ensure that the wrinkled parts of petals are out of focus, or obscured by another part of the flower.
The outside of this flower was a bit worn, so I chose to emphasize the stamens instead.
3. Centering the subject
This is a common mistake in all types of photography – placing your subject in the dead center of the frame.
While this might make sense from a visual perspective, it generally results in an uncomfortable, less-than-desirable image. The composition feels imbalanced or boring.
How can this problem be fixed?
Placing this flower off center allowed for a slightly stronger composition.
Instead of placing the subject in the center of the image, place it off to one side. Try using the rule of thirds. Additionally, you might add some dynamism to the composition by tilting your camera and placing the flower along a diagonal line. This will ensure a much more dynamic image that holds the viewer’s eye.
4. Using busy backgrounds and foregrounds
A fourth macro photography mistake often made is using foregrounds and (especially) backgrounds that are messy.
For example, messy backgrounds might have splotches of colors, might be crammed with slightly out-of-focus elements, or have sudden transitions from light to dark or dark to light. Messy foregrounds, on the other hand, consist of branches, twigs, or other flowers that distract the viewer and get in the way of the main subject.
While this bleeding heart photograph may seem chaotic, it’s not particularly messy—there is a clear point of focus (the flower) that is not dominated by the background.
How can this problem be fixed?
I write about this a lot, but that’s because it’s such a common (and easily rectified) problem. It involves a bit of measured consideration before shooting. Simply make sure there are no distracting foreground or background elements. As discussed above, these include branches, twigs, or sticks. It also might simply be contrasting colors or dark spots.
Notice the smooth, uniform background in this flower image.
5. Capturing a subject as the subject
This final macro photography mistake is a bit less straightforward: capturing a subject as that subject.
What do I mean by this? In truth, it’s not all that complicated. Basically, macro photographers often see an interesting subject and attempt to photograph that subject efficiently. The problem is that the subject then lacks interest. It feels like it’s part of a snapshot when you want it to feel like a deliberate photograph.
How can this problem be fixed?
If you photograph a flower, don’t try to just capture it as a flower. Look for interesting aspects of the subject. What is it that made you want to photograph it in the first place?
Try to go beyond that basic “it’s a flower” essence, and communicate something about the flower. Does it have a photogenic center? Colorful petals? A beautiful shape? Emphasize this through your photography.
I chose to get extremely close to this dahlia in order to emphasize the pattern of its petals.
Conclusion
I have discussed five common macro photography mistakes, as well as a number of simple ways to fix them. By following these guidelines, you should be able to enhance your macro photography and ensure consistently better images.

How to Choose the Right Color Profile For Sharing Images Online
Many people have problems with the color of their photos when they publish them online. There are several reasons why this might be so, but the most common culprits are the color space of the image and whether or not the profile is embedded. Both color settings can radically affect web browser color and how your photos look.
Let’s look at some of the potential pitfalls more closely.
The Importance of Embedding the Color Profile
Whenever you edit your photos in an editing program like Photoshop, you are doing so using a specific RGB working color space. To be sure of preserving the color you see when you’re editing, you need to embed the profile before saving the image.
In simple terms, the ICC profile is a translator. It enables different apps and devices to interpret the color as you intended. If you get into the habit of embedding profiles into your images as you save them, you’ll reduce the chances of color looking wrong on the web or in print.
The rich color in this ProPhoto RGB image will look okay in many browsers despite not being sRGB as normally advised. If it looks muted and drained of saturation to you, it’ll be because you are viewing it in a non-color-managed browser. By embedding the profile, I’ve given it the best chance of looking as intended to the majority of people. On a wide-gamut monitor, the colors will pop a bit more.
Embedding the profile into an image adds about 3-4 kB to the file size, so the only time it makes sense to exclude it is when you’re uploading vast quantities of photos to the Internet.
If you must leave the profile out, making sure that the image is in the sRGB color space will limit any resulting damage. Two or three of the more popular browsers will still display the color faithfully because they automatically guess the profile correctly (i.e. sRGB).
Although most browsers have improved in their handling of color recently, it’s still good practice to embed the profile. Don’t leave it out without good reason.
Because the profile has been left out of this same ProPhoto RGB image, the brightness and color will look terrible in most browsers and on most monitors. By contrast, a missing profile for an sRGB file would be undetectable to a large number of people.
How to Embed the Profile
Embedding the profile into images is usually just a case of checking a box when you export the photo. If such an option doesn’t exist, the default will either be the predefined working space of the program, or it’ll be sRGB for web-specific output.
If you want to check the color of your web images before publishing, open them directly in a browser (preferably a reliable one like Chrome) and see how they compare to the original in your photo-editing program. Be a little wary of uploading images to platforms that strip out the profile, though these will not typically be photo gallery sites.
Embedding or stripping out profiles usually only requires you to check or uncheck a box when saving. This is the “save as” pane in Photoshop.
Converting to Profile
You can use “convert to profile” in Photoshop to create an sRGB image, which is the safest color space choice for the web. Be sure not to overwrite the original file and save it this way, because larger color spaces are a better choice for outputs such as inkjet printing.
Do not use “assign profile” for profile conversion, as it causes a color shift and is not meant for this purpose.
Using “assign profile” in Photoshop to convert between profiles will cause a color shift. Color in the right-hand image above has gone flat as a result of assigning an sRGB profile to an Adobe RGB image. You must use “convert to profile” if you want to create an sRGB version of your photo for the web.
Why Monitor Gamut Matters
Color management needs at least two profiles to work (image profile and monitor profile in this case). If you publish images without profiles embedded, you’re relying on the viewer’s browser to guess the color space correctly.
When color management is absent from the browser or app for whatever reason, the following statements are true:
- An Adobe RGB image looks roughly correct on a wide-gamut display.
- An Adobe RGB image looks muted in color on a standard-gamut display.
- sRGB images look roughly correct on a standard-gamut display.
- An sRGB image looks oversaturated in color on a wide-gamut display.
Note that an Adobe RGB image without a profile embedded looks muted in most situations and must be avoided. Browsers will guess the color space to be sRGB if they guess at all.
The graph above shows the difference between a standard-gamut Dell monitor (colored outline) and the sRGB profile (dotted outline). Even on a regular desktop monitor, some colors are quite likely to exceed the sRGB color space and look too saturated when viewed in Microsoft browsers.
In the monitor above, it’s reds that are most exaggerated in that situation. If you haven’t profiled your monitor or if the gamut of the screen is contained by sRGB, you won’t encounter this.
Browser Behavior 2018
To understand color profiles, it helps to know how different browsers behave with color. I tested five browsers for this article to give you an idea of what to expect. Feel free to query this if you think any of these observations are wrong:
Google Chrome
Chrome is a fully color-managed browser that assigns sRGB to any “untagged” images (i.e. those without profiles embedded). It reads all embedded profiles.
Opera
Opera is a color-managed browser that automatically assumes photos to be sRGB if the profile is missing. Like Chrome, it reads all profiles, including Adobe RGB or ProPhoto RGB.
Firefox Quantum
You can configure Firefox to assign sRGB to any untagged photo. It reads all embedded color profiles.
If you happen to run two monitors, Firefox does not maintain full color management across both of them. For optimum color, you must dial in one monitor profile then stick with that monitor. This only applies if your monitors have custom profiles.
Microsoft Edge/Internet Explorer
Microsoft Edge has a half-baked solution to color management. It reads different color profiles and converts everything to sRGB for display. The main problem is that it doesn’t use the monitor profile. Thus, it works best if your monitor does not exceed sRGB in gamut. Otherwise, you’ll see wayward colors.
Safari (for Windows)
Safari can read profiles in images and uses the monitor profile (unlike MS Edge or MS IE), but it does not assign a profile to an image if one is missing. In that situation, it displays color wrongly as Microsoft Edge does.
In Photoshop, you can use “Monitor RGB” proof colors to show you what the photo will look like in Internet Explorer on your own monitor. You’ll need to convert the image to sRGB first. If colors look brighter than they do without proofing, it means your monitor’s native gamut exceeds the sRGB profile.
A second experiment is to view the proof colors of an Adobe RGB or ProPhoto RGB image using “Internet Standard RGB”. This will show you how photos in bigger color spaces look on the internet if you omit the profile.
Choosing sRGB for the Web
The reason why sRGB is a safer choice of color space for the web is that most displays or monitors are not wide-gamut. Thus, if the profile goes astray or is stripped out, or if a device or app doesn’t support color management, the color will still look okay. This is what Microsoft’s browsers rely on to work.
If you want the color of your photos to look “okay” to the widest possible audience you need only do two things:
- Make sure the image is in an sRGB color space either by using it as your working space or by converting to sRGB before uploading to the web.
- Embed the sRGB profile into the image before saving.
Photoshop’s “Save for Web” lets you convert to sRGB at the very last moment by checking a box. If you leave the box unchecked, the photo is saved in whatever color space you edited it in. You can’t strip the profile out with this checkbox: it’s purely for conversion.
Other Choices: Adobe RGB and ProPhoto RGB
Since most popular browsers are now color savvy, the possibility of using other color spaces on the web exists. You could, for instance, publish photos with an Adobe RGB or ProPhoto RGB profile embedded, and they’d still look good to most people. To a minority, they’d look better.
The color of wide-gamut monitors typically exceeds Adobe RGB in places. Hence, there is theoretically a reason for publishing photos in ProPhoto RGB. However, this is offset by the dire color that results when the profiles are missing or ignored. It’s high risk.
Adobe RGB is an interesting prospect for the web because it still benefits users of wide-gamut monitors. Importantly, it doesn’t look as bad as ProPhoto RGB when things go wrong. However, if you publish in Adobe RGB, you’ll still be doing so for a relatively small audience.
If you do use these wider-gamut color spaces for the web, you absolutely must embed the profile. As soon as that goes astray, the color in your photos will look a bit flat to many people. In the case of ProPhoto RGB, it’s likely to look awful.
This 3D diagram (above) shows the sRGB profile encompassed by the profile of a wide-gamut monitor. In particular, you’ll note the extended range of cyans and greens in the latter.
The idea of using larger color spaces on the web is appealing, especially if you’re a landscape photographer for whom these colors are often truncated. It means you’d be making more use of your camera’s capabilities. However, it’s inherently riskier and you’ll be playing to a relatively small audience. The safe choice is still sRGB.
In Summary
Although modern browsers are more flexible, sRGB is still the safest choice of color space for the web. Again, this is because it roughly matches the gamut of most electronic displays. Using bigger color spaces risks draining your photos of color, especially on tablets or smartphones that may not be color-managed.
I hope this has been of some use. Feel free to ask questions if you need any clarification.

Why World Cup Balls Look So Weird Every Tournament
Why does the World Cup ball look so different year after year? It's a question we posed to John Eric Goff — a physics professor at University of Lynchburg and author of "Gold Medal Physics: The Science of Sports." Turns out, some of those changes haven't been for the best. And have caused more problems than they solved. Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more. Subscribe to our channel and visit us at: https://ift.tt/fxZ2E2 TI on Facebook: https://ift.tt/1fEbtRI TI on Instagram: https://ift.tt/1S8jzxH TI on Twitter: https://twitter.com/techinsider -------------------------------------------------- Following is the transcript of the video: The typical soccer ball looks like this. Black and white with a bunch of these panels. But that’s not what the World Cup balls look like. So, what’s going on? First things first, you want a soccer ball to be as spherical as possible. John Eric Goff: “In the old days, we had balls that had the bucky ball shape, the Epcot Center shape, 20 hexagons, the 12 pentagons. And that was a very good approximation to a sphere. But starting in 2006 with the World Cup in Germany...there were more creative ways to make a sphere.” New technology enables Adidas to start designing the balls with fewer panels. Which created a serious problem. Because fewer panels means fewer seams. And, more importantly, a smoother surface. Goff: “If the ball gets too smooth, the air resistance goes up. It’s like kicking a beach ball.” And that’s exactly what happened with the 2006 Teamgeist ball. Players complained the ball didn’t go where they expected it to. So, in 2010, Adidas compensated by adding some texture to roughen up the surface. Problem solved, right? Goff: “Jabulani was a spectacular failure because it was not rough enough. When the ball would be kicked at certain speeds, you’d notice it would slow down dramatically part way through the flight.” And the panels kept disappearing. The 2014 ball had the fewest panels yet. But this time Adidas compensated. Goff: “Despite having two fewer panels, the total seam length around the ball was 68% longer than Jabulani.” So, at least, the ball had the right amount of roughness this time and flew farther than the 2010 ball. As for 2018: Goff: “The total seam length is actually 30% longer than the Brazuca! So now you run the risk of the ball being a little too rough.” Adidas compensated for this by also making the seems shallower. And a study that Goff led showed that the Telstar 18 performs similarly to Brazuca. But it still has a bit more drag, and might not travel as far on high-speed kicks. Regardless, all of this begs the question: If the goal is to produce a ball that’s similar to what athletes practice with for years, then why does the World Cup ball keep changing? Turns out, it’s not about the players or the game at all. Goff: “There’s a new ball released for every World Cup and I think the primary reason is money.” The 2018 World Cup ball costs over $100. Goff: "And these balls fly off the shelves!” That’s a pretty big investment, considering you can get a regular ball for under $20. To be fair: Goff: "The technologies used to make these balls is much much greater than what we used as kids. The panels on these balls are thermally bonded, it helps keep the water out of the inside of the ball, keep the ball from getting waterlogged and making it heavier." That’s nice but is it really worth it? We’ll let you decide.

Why does the World Cup ball look so different year after year? It's a question we posed to John Eric Goff — a physics professor at University of Lynchburg and author of "Gold Medal Physics: The Science of Sports." Turns out, some of those changes haven't been for the best. And have caused more problems than they solved. Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

Black and white with a bunch of these panels. But that’s not what the World Cup balls look like. So, what’s going on? First things first, you want a soccer ball to be as spherical as possible. John Eric Goff: “In the old days, we had balls that had the bucky ball shape, the Epcot Center shape, 20 hexagons, the 12 pentagons. And that was a very good approximation to a sphere. But starting in 2006 with the World Cup in Germany...there were more creative ways to make a sphere.” New technology enables Adidas to start designing the balls with fewer panels. Which created a serious problem. Because fewer panels means fewer seams. And, more importantly, a smoother surface. Goff: “If the ball gets too smooth, the air resistance goes up. It’s like kicking a beach ball.” And that’s exactly what happened with the 2006 Teamgeist ball. Players complained the ball didn’t go where they expected it to. So, in 2010, Adidas compensated by adding some texture to roughen up the surface. Problem solved, right? Goff: “Jabulani was a spectacular failure because it was not rough enough. When the ball would be kicked at certain speeds, you’d notice it would slow down dramatically part way through the flight.” And the panels kept disappearing. The 2014 ball had the fewest panels yet. But this time Adidas compensated. Goff: “Despite having two fewer panels, the total seam length around the ball was 68% longer than Jabulani.” So, at least, the ball had the right amount of roughness this time and flew farther than the 2010 ball. As for 2018: Goff: “The total seam length is actually 30% longer than the Brazuca! So now you run the risk of the ball being a little too rough.” Adidas compensated for this by also making the seems shallower. And a study that Goff led showed that the Telstar 18 performs similarly to Brazuca. But it still has a bit more drag, and might not travel as far on high-speed kicks. Regardless, all of this begs the question: If the goal is to produce a ball that’s similar to what athletes practice with for years, then why does the World Cup ball keep changing? Turns out, it’s not about the players or the game at all. Goff: “There’s a new ball released for every World Cup and I think the primary reason is money.” The 2018 World Cup ball costs over $100. Goff: "And these balls fly off the shelves!” That’s a pretty big investment, considering you can get a regular ball for under $20. To be fair: Goff: "The technologies used to make these balls is much much greater than what we used as kids. The panels on these balls are thermally bonded, it helps keep the water out of the inside of the ball, keep the ball from getting waterlogged and making it heavier." That’s nice but is it really worth it? We’ll let you decide.
