1. I would like to put the cash into a DSLR but I have no idea what to look for or what I need. If you people would be so kind as to help me I would be forever in debt.
2. these to be critiqued. ANd maybe some explanations on how to post photos easier
It looks like you have a good eye for composition and color. You will do well with whatever you get. The thing about SLRs (DSLRs included) is that you are buying into a "system". If you buy a Canon body then you will have to buy Canon lenes and then because you have those lenes the next body you buy will have to be Canon. Same goes for Nikon. Look at the systems and if you care about it look into the used markets too. New Nikon DSLR bodies can work with 30 year old manual focus lenses. Canon compatability does not go back quite so far but if you don't already own SLR equipment you may not care.
If you continue to do the same type of photograpy as the four examples you posted you do not need a lot of features on the camera. Go to a sore a handle the equipment yourself. Be sure and look at the lenses. new buyers tend to spend to much time thinking about the bodies. those are cheap compared to a bag of quality optics or a set of lighting equipment You will upgrade the body in three to five year because that technology is moving fast but a lens can be a lifetime investment. I am still using a late 1960's vintage macro lens with my Nikon DSLR. It is "way sharper" than the D50 can record.
About "megapixels" when comparing cameras take the ratio of the square root of the total pixel counts. ths will tell you the ratio of the resolutions. for example a 16MP camera has twice the resolution as a 4MP camera (not four times) Using this method you find that 6MP is very close to 8MP. What matters is pixels per inch in the final print. Another method is to compare the number of pixels along the longer edge of the frame. But "megapixel" is a marketing term
Everyone will tell you to buy whatever camera they happen to own. "Buy the Canon 5D". "No get a Nikon D50 and save a couple grand." The Rebel XT is great, the rebel XT feels like a plastic toy. I like Olympus, look at the Evolt. Keep the Minolta and scan the negatives. Actually all of the above is correct.
Next set a budget. Select either Canon or Nikon then buy the camera and "kit lens" that fits the budget then go get a 50mm f/1.4 or f/1.8 lens and go shoot a couple thousand frames. then think about what other lens you might want.
If you are into sports or wildlife you would want a long fast lens. be prepared to spend a four digit price. But from your examples maybe you'd want a fisheye or 10-20mm zoom. You don't know now.
