p.1 #5 · How To Make Freckles "Pop" | |
It's just a matter of increasing the contrast between those two specific tonal values.
The simplest way to do that in PP is to dupe the background layer and change the mode of the dupe layer to "soft light".

That mode takes light areas lighter and dark areas darker increasing the contrast between them. Adjust the opacity slider on the dupe layer to taste or if you want to apply the effect only to selected areas add a black bitmap mask to the dupe layer then selectively erase the mask where you want the added contrast.
A more esoteric method in Photoshop is channel blending via the "Apply Image" function. It involves blending the channel in an RGB copy of the file containing the most freckle detail into the Luminance channel of an indentical copy in Lab mode saved in .psd format:

1) Open both files
2) In the LAB file open Channels and press cmd+1 to select the L target channel, then press ~ so the color image is displayed in the edit window. This step needs to be done correctly for the technique to work. The channels window should appear as in the example above with only the L channel highlighted.
3) Open Adjustments > Apply Image Select the RGB file and the Blue or Green channel as the source, whichever has the most detail in the freckles. I used the Blue channel for the example above. Apply the Blue channel information to the L channel in overlay mode then adjust opacity by eye.
4) Convert the Lab file back to RGB mode and save.
Another way to make the freckles stand out would be to shoot with the camera in B/W mode with a green filter simulation.
