If you shoot RAW, most of these settings can be applied to the file in Post Processing. At least they can with my Sony cameras and the Sony RAW processor. This saves a lot of time trying to figure out compensation, vivid/landscape, contrast, sharpness, etc., before you take the shot.

Not if you blow out the highlights!!!

This reminds me of a big subject on another list on the web. The subject is, please take notes, iso invariance. As best as I can tell from all the mumbo jumbo what they are saying is that one need not adjust the iso for lower light, just bringing things up in post is EXACTLY THE SAME!!! As best as I can tell, they mean that you can use the camera's amplifier or you can use the software's amplifier, the result is the same.

I'm not on either side of this, no dog in the fight.

So Linda--whenever you want a black background, do you always use the EV to get it

On a beautiful sunny day, set exposure to -1/3 stop. It makes the colors more saturated. It worked with 35mm and it works with digital.

I would only try that approach when there are already deeply shadowed backgrounds and the subject is in bright sun. I've attached another example below (shot with bridge camera SX50).

But my shooting habits have changed a lot since 2015. Not only did I learn about auto ISO here on UHH, but I have discovered the wonderful world of M4/3 (mirrorless Panasonic and Olympus) in which I can see exposure through the viewfinder. Also I've become wobbly enough to need faster shutter speeds.

So now I always set aperture and shutter speed based on conditions and desired result, set ISO based on the exposure I want or use auto ISO in quickly changing light conditions (or such as trying to track a flying bird).

Appreciate your asking

Does not apply if you use actual photons for the compensation, though. If you use a wider aperture or slower shutter speed, iso invariable is not a factor.

Having to amplify a dark exposure is not optimum, whether the "amplification" takes place in-camera or in post processing. Ideally the camera uses its base ISO and uses shutter speed and aperture to capture sufficient light for the desired exposure. The problem is, circumstances don't always allow the capture of sufficient light and amplification of one sort or another is then required.

The dogs will grrrrrlll a bit though. Brightening in post may / may not be exactly the same. It depends on the camera type and the extent of the change. If you don't have an ISO invariant camera, you'll have less success with the 'brighten in post' approach.

I use EC all the time, usually shooting in shutter priority mode. My Panasonic FX1000's thumb wheel, with a press, toggles between shutter speed and EC. I simply look through the EV and adjust to what pleases me then take the shot.

I see several have commented on the iso invariance comment I made. Thank you. I was and am still unable to understand this, as I'm not a sensor designer or an electrical engineer, or physicist.

I would like CHO CANON to explain his comment.A camera of a different type was not mentioned in the posts on the other list. What is an iso invariant camera? And how do I know? And knowing that will make my life better? AS I said before, this is all confusing to me and like Sgt. Schultz, I know nothing.

The horse image at the bottom of this example is the best example I've seen. https://photographylife.com/iso-invariance-explained

I've seen a website that answers the question of: is my camera ISO invariant? Google didn't give me the desired link in the first page of results, but it's out there. As a general rule, EOS bodies are not. But, I'd be more confident in that "rule" for today's latest releases if I could see an assessment from the testing results.

Thanks. I'm not so sure that this is quite the big overarching subject that the link says it is, but I obviously don't live in their world. I examined the iso invariance link you posted, but wow, I will need to read it more that once to even get just a bit confused. I think sitting in front of the fireplace with a cigar, a glass of scotch and the article might get the job done, but what remains unanswered is the crux of this all: how will knowing this make me and my life better?

Don't let the photographer you were yesterday stop you from buying a new camera tomorrow.

No, I would buy a new camera today to replace the one I think is unsatisfactory were it not for one thing...no money for that. But I do know exactly why I wish to replace one I have now.
