Firstly, I don't want to explain anything at the beginning. I will start with my 3 experiments and results then let you guys think and discuss.
My equipments in this experiment : Pentax K5 with 40mm XS lens and a bag of snack.
Environmental conditions : Indoor, WB auto, ISO1600, JPEG.
--------------------------------------------------
1ST experiment, I just took 4 shots by changing f and shutter speed manually. However, they were changed in order to get the same amount of light by step of 1/3EV.
Picture 1 was taken with f2.8 and speed shutter of 1/100 s
Picture 2 was taken with f3.2 and speed shutter of 1/80 s
Picture 3 was taken with f3.5 and speed shutter of 1/60 s
Picture 4 was taken with f4.0 and speed shutter of 1/50 s
You guys better check EXIF of them.
Here is the result.
