65 Jun 17 Comment Good subject here and you have captured and nicely composed the subject within the frame. The background is nicely balanced in regards to clarity and tone. That being said, the main subject is somewhat soft, and being the main subject is a bit distracting.

I took your image and using a few passes of the Sharpening brush in Photoshop, was able to sharpen up the main subject along with some of the web. Adding a bit of clarity (micro contrast) brought out more of the little critters details. Finally I cropped in a bit to make the spider a larger portion of the entire image, however this final step may be more dependent on the makers eye.

I would have like to see a bit more about why and how you took the image (beyond the bare camera information). Each mage has it's qwn story, and this is the place to tell it.

65 Jun 17 Comment Most of the focus stacking applications have a few different algorithms to pick out the “sharp” parts of an image. This is the case with Zerene Stacker with the use of the “pmax” and “dmap” methodologies (don’t you just love the imaginative names they come up with ?) It is difficult to anticipate which method will work best with an image, so I too generally run both methods with each image. Once I have finished running both modes, I go into the “retouching” mode selecting one of the modes as the main image (the image I am going to “retouch” with the most “good” areas) and selecting the other as the “source”. I then paint in the good parts from the source file onto the main image. This way I get the best of both worlds in my final image. This takes a bit of practice, and at times I start with one image being the main image only to discover that the other is the better of the two (sigh).

In this image there are some areas that are overly soft, specifically the antenna, the underside of the body (in shadow) and where the wing meets the body. I suspect that these areas were sharper in one of your stacked output images (but not so much in the other). Since you went to so much effort to get to this point, try going back, restacking the image a see if the “retouching” process doesn’t allow you to select the “best of both worlds” from your output files. I find that retouching is a critical final step in using the stacking software and do some sort of retouching with most of my stacked images. Luckily, this is really easy in Zerene Stacker.

I really love the fact that you saw an opportunity to capture these critters in a way the we don’t normally see, and came up with some imaginative ways to make this happen.
