I don’t generally photoshop images beyond small crops and levels tweaks, especially for field and behavior projects. However, stylized studio work serves a different purpose, so I allow myself more digital liberties.

I don't generally photoshop images beyond small crops and levels tweaks, especially for field and behavior projects. However, stylized studio work serves a different purpose, so I allow myself more digital liberties. How much do I manipulate studio captures?

Here is a small turtle ant project from this morning:

This image is bright and clean, but it didn't start that way. The original exposure is duller:

A closer look at before/after details:

The steps from A to B:

  1. Crop and rotate the image so ant is vertical (in Adobe Lightroom). While I normally compose on-camera as much as possible, I also prefer to shoot live, healthy subjects, as the resulting photos look more natural. This ant was running around during the session, so I traded away some magnification and framing for the sake of realism.

  2. Set the background to white and correct the color cast (in Lightroom).

  3. Increase contrast, shadows, and highlights so the values for the body of the ant go from near black in the darkest shadows to near white in the lightest hairs (in Lightroom). These adjustments give the image some zing.

  4. Reduce noise slightly (in Lightroom). The original exposure was at ISO 400 for reasons of keeping the two flash units at lower power. Low power flash recycles more quickly, allowing for more exposures and a greater likelihood of capturing the intended pose in a very active subject.

  5. Remove unwanted specks of dirt from the substrate and from the ant (in Adobe Photoshop). Photoshop's tools for erasing spots are more flexible and powerful than Lightroom's!

  6. Add extra white space below the ant and re-frame for final composition (in Photoshop).

  7. Apply moderate unsharp mask (in Photoshop). The original image was taken at f/20 for expanded depth of field, but such a small aperture softened the image.

Once finished, I uploaded the image to my professional galleries where turtle ants fans around the world* can order prints.

*existence of turtle ant fans beyond the author remains, at this point, hypothetical conjecture.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
