Hi Alex
Whoops – I assumed the lens had IS, my bad. However, I have noticed that the IS takes a little time to “kick in”, (which makes sense), so in my early outings it did not appear to help my low light photos as I wasn’t allowing it time to lock on and do its stuff.
The sharpened version shows lovely detail in the Egret’s wing feathers, really nice!
I did read that RAW frames straight out of the camera do require some degree of sharpening simply due to the nature of RAW captures.
Another interesting piece I came across indicated that our eyes, like 35mm film, are non-linear in response to tones whereas CCD (and CMOS) chips are totally linear with a Gamma of 1. IIRC, our eyes and film have a Gamma of maybe 1.8, so they can better distinguish subtle differences in dark tones than light tones?
I found that with the 40D, I was under exposing as I was used to 35mm film and exposing for the shadows, letting the highlights look after themselves. It seems that with DSLR’s one should expose to the right of the histogram as the sensor can handle bright whites (not level 255 blow outs) better than film and this then prevents shadows from becoming too noisy.
I found this
article to be very helpful on understanding the histogram. And
this one on exposing to the right.
I’m not sure of your experience and background, so my apologies if I am writing kid’s stuff!
Cheers
Dennis
