Please give feedback on Photoshop editing...

So you landed at ISO 100 with a shutter of 1/400 based on your desired aperture setting.

If the above statement is true, sounds like you had a decent amount of light.

I would go usually slightly with sligtly different order:

IF a DOF does not really matter much [If you do not care if it's either f4 or f8], then the first thing I would set is a minimal shutter speed I feel comfortable for situation.
Only then choose the F-stop and then balance all out with ISO.
If ISO is too high and won't perform optimal [Smaller issue with newer cameras, but I have old sh*t usually, if not renting out], adjust F-stop and shutter accordingly.

So just giving a quick update....

I went just randomly shooting with a bench and doll in my backyard they other day, here is how I believe my mind works best with the camera....

Manual mode
Adjust ISO to 100
Set Aperture to desired depth of field
Set shutter speed to around what the reciprocity rule states...check image.

Adjust shutter speed for less /more light...if needing more light than what is provided by 1/400 adjust ISO.

Suggestions?

"Set shutter speed to around what the reciprocity rule states...check image." - remember that this should be your minimum, not necessarily your ideal shutter speed.

Suggestions:
Move the doll to different lighting situations - sun from front, side, back - shade - morning, daytime, evening and night.
Practice with different aperture settings and distances from the subject and distances from subject to background to get a feel for what can be done by just changing your position and the aperture.
Practice shooting moving subjects with different shutter speeds and panning your camera. What speed do you need to stop a person's motion while they are walking, a car's motion, etc.
One other thing to practice is to see at how slow of a shutter speed you can successfully hold your camera at different focal lengths. Good info to know when shooting into the evening.
Practice shooting with different ISO settings to see what you consider the upper limit of your camera for your taste.

I think you get the idea - practice, practice, practice.

Put doll on rotating platform or vibrating platform to test shutter speed for stopping motion, which will change the other two factors...
