I'm not an expert but it probably depends on your camera. I know I have read on my D500 that recovering underexposed shots gives similar results to shooting at a higher ISO. Your mileage may vary. Either way, you tend to lose some contrast and of course gain noise in the finished product.

That's a very nice photo. Perhaps the frog was that bright, but he almost looks over-exposed now. You might try adjusting your "whites" slider down a bit or the "highlights" slider.


Since someone else pointed it out first, I think so too.

Shadows-Highlights applied with a slight edge darkening vignette.

This now looks slightly flat and lifeless. OP's adjustments looked better to me, on my calibrated, graphics quality monitor.

Add contrast then. And while your at it you should take out those distracting out of focus elements.

Thanks. It's downloadable now.


I don't see visible noise. You must have shot in RAW?

Yep. Luminance smoothed a bit in LR

You can never go wrong under-exposing.

A little contrast helps.

I was out shooting some sunset shots the other night, and set the exposure to -2.3 stops. Then forgot to set it back. Oops. Today I came across a gray tree frog, got some nice shots, and didn't realize they were badly underexposed until I saw them on my computer. LR to the rescue, and they turned out reasonably ok (see attached).

Guess I'm a slow learner; I've made this mistake before.

Question is, how much is lost in IQ by this sort of blunder and fix? I'm guessing that since 2^2.3 is about 5, the net effect would be the same as if I'd exposed it correctly and used an ISO five times bigger than I used. I shot the attached at ISO 320 (D7000 with 40mm micro @ f16) and would say the result looks better than if I'd shot it at ISO 1600.

Slight to moderate underexposure, especially with your camera, is almost always preferable to overexposure. I think you might have gone too far to correct the image, so it has a washed out appearance. I took the liberty to play around with it, added some contrast, local color saturation (on the log), made the frog darker and added some microcontrast, masked the log and frog separately from the background, and gave the background a darker, slightly less saturated look , as well as removed detail so it is less sharp, to bring the frog and log into prominence, and spent a few minutes taking out that annoying out of focus blade of grass. This would not be a final edit - there are other things like flaws on the blades of grass that I would take out, but it shows what can be done, and how I would have interpreted the scene.

If that's your only mistake I would say you are ahead of the game.

I would not worry about underexposing using LR. It does a good job of recovering details.

That's how it's done on Madison Ave.

I take it you've never worked with a Creative Director for an Advertising company or Corporate Graphics department . . .
