Well, because I really have no clue what I am doing
I usually use the editing that comes w/ picasa or whatever 30 day free trial photoshop offers- I currently have Lightroom 3 dwnloaded (about 26 days left to use)
1) So, I should always use 100, or 200 ISO for daytime photos? [Yes, ISO 100-200 is most effective for everyday photographs, night time photos may require higher ISO.]
2) She was wearing that shirt all day- was not a 'planned' shot. [Best tip for this situation and many others, look around you (for a contrasting color) something is always just appealing over your shoulder.]
3) re: Shutterspeed- I didn't set that on my own (that I know of) I usually just go off the light meter indicator (try to turn the dial until it stops in the middle or one or two stops to the left.: thinking that's what makes it a correct exposure.( not too bright, not too dark). [Future fail safe here is a tripod or monopod, for now use a fast enough shutterspeed to prevent camera shake but not underexpose the image. Your light meter will give you guidelines.]
I am very new at this, and still trying to figure it ALL out. I appreciate your response. I will read more tutorials: sometimes though, I still don't get it and wish I had someone right there- "hands on" experience- or tell me step by step in a way what I should do, at least till I can get the hang of it.
