Re: Half Moon
Very nicely done Jim,

Re: Half Moon
Very nice, Jim. May I ask why did you use ISO 100 and not the lowest 50?

Re: Half Moon
It doesn't look right too me; the contrast is too high. I'm not saying I can do better because I can't; it just doesn't look right.

Re: Half Moon
Thanks for the comments.
Alis,the truth?I forgot that the 5D has ISO 50
Still new to the camera.
I'll give it a try next time.
Arith,you are correct.I boosted contrast to bring out the crater details.

Re: Half Moon
ISO 50 isn't a true ISO - they just under-expose the shot my 1 stop and up-shift the result to compensate; bottom line is it gives you more noise, and 1 stop less dynamic range. Best to avoid it unless you need the slower shutterspeed for some reason. Originally Posted by Alis

Re: Half Moon
Colin,
Thanks for the heads up.I never used the 1/3 stop ISO settings on my 50D either.

Now I want to know where do you get this information from? I mean this specific piece of knowledge?Last edited by Alis; 28th October 2009 at 02:04 AM.
