Here's a photo.. from today... (advice welcome.... I dont consider myself a professional or even an enthusiast or really even an amateur.. so "critique" is not the right term for sure... LOL)

I'm totally new to DSLR.. just bought a 30D a bit over a week ago.. I used it at the Phoenix Nascar race and got some really nice shots .. at least I think so...(I dont know much about it... really)

Anyway.. I bought the camera after having a Olympus 750uz which worked pretty well... I normally photograph wildlife.. mostly semi-captive type outdoor subjects.. so I bought the EF 100-300 USM lens I just couldnt afford the "L" lens I wanted.. maybe one day. (translation... I'm saving my pennies !)

The big thing is that most of my photography are.. well...... VERY remote.. that meaning I may hike 1/2 a mile in rough country.. or 5 miles in rough country ... so weight and size is a limiting factor... fwiw.. (translation... 70-200 2.8L is OUT of the question ! )

Anyway. on to the photo.. I took this in the back yard this afternoon.. partly cloudy (quickly changing light) but the subject was in the shade mostly... I take responsibility for the noise (ISO 800) this is unprocessed exif should be included I think... shot in AV mode.. If the exif is not there let me know and I'll provide it...

I dunno if I'm doing this stuff right is all... I seem to fight shutter speed with ISO with f/stop ... so if I need more shutter speed or specific DOF I seem to constantly need to increase the ISO if the lighting is poor to get "there" I guess the lens is a bit limiting... ?? Dunno? I really think the lens will be fine for what I bought it for.. (which is NOT for portraits or birds ...fwiw)... I just havent had a chance to use it for that yet...

Oh.. one more thing.. just wanted to say thanks to Loupey (sp) for the bucket of light analogy.... it is VERY helpful IMHO...

Thanks...
