So what's the conclusion? I know the basics of what is shutter speed, aperture, ISO etc etc..and i'm using digital camera.. so what's the conclusion?
Does aperture and/or shutter speed affect the saturation of colors?
TS, your simple innocent query has been 'complexified'.
Let me try.
I did try similar tests few years ago (when I got my D70)- just exploring then - and just few days ago I noticed something similar to your query.
Assumption:
For a given situation/condition - only consider A,S and colour - (lens, film, WB,etc dun come in)
Objective
To see any color variation by playing the A/S, still acheiving the correct exposure.
Observation
1 my observation then: hardly can seen any difference; EXCEPT, when stopped down to low, it appeared better, and if I recalled it was most probably it is slightly underexposed - compared with initial 'correct' one. You can verify this easily.
2 Observation 2: However, when I wanted to increase the shuttle speed, and A opened max., I increase the ISO. You can see that the color pale - to a point you thought you took the pic with a freebie cam. I also observed this few days back when my friend is trying how good his D300 noise control is.
MY own observation/conclusion (my belief only - not enough test to demo)
*** A/S = min effect on color (at least within the commonly used range ..)
*** ISO = very significant
The guy in flickr, maybe he is profound expert, or he also half a bucket of ????! based on his puesdo scientific theory.
(BUT theoretically - there should be some effects - read somewhere about non linearity in the response - dun understand also.)
