Wow, so glad I found this forum and website. I have enjoyed taking photos for a long time. While in high school I did a ton of black and white and loved the art of taking and developing. While in college did not have the most time to dabble in the art anymore. Worked at circuit city and bought a decent digital point and shoot and have taken some pretty good shots.
My wife has recently let me go out and finally buy a digital slr (rebel xti/400d) which I enjoy allot. We recently got back from our vacation in Gatlinburg Tennessee and I took some good nature and waterfall pictures. Some questions I have found while playing with camera in the field is.....
1) why with higher iso do you get fewer pictures on 1 gig card? Does an iso 800 save more info than say a 100 iso? Ok, well I know it does, but what is reasoning behind this? I would think the sharper iso 100 would have more info and the picture with more noise (iso 800/1600) would have less info.
2) on a 10 meg camera, is there that much noise on an 800 iso (for indoor photography)? I have a new son (16 months old) and have been shooting pictures all the time. I know with film, lower iso=lower grain. In all reality these will only be processed at 4x6, maybe 5x7, and very few large prints. Will there really be a noticaple difference on prints with such a large magapixel rating say at 4x6 prints. At what point (print size) do you start seeing noise. Largest prints I will most likely do are 8x10 with very few poster size prints.
3) I have been getting some books from the library and constantly reading more and more posts here to better my photography. I have a good grasp on composing and rules of thirds and all the fun stuff to make better pictures and framing of pictures. Are there any good books people would recommend that gives more info or techniques for more advanced photographers? Most of the stuff I keep seeing in books is for beginners.
again, i will be doing more posts as i learn more. Thanks for any help.
