can you do green screen with a DSLR?

I was thinking of doing some green screen like effects like using a green sock over a limb and replacing it with something else in post.

Can i do this with a DSLR?
 
Yes. There is no reason a DSLR would be different than any other camera- I've seen people key out footage taken on a cell phone (no joke!).

I'll admit its easier on some cameras versus others, but working around the limitations is practically the DSLR motto. Avoid shallow DOF and compression artifacts (fast motion, etc) and you should be fine. I've done it without a problem.
 
im in the middle of a green screen shoot with my 50mm 1.8. Just be sure to stop down your apeture a bit
 
I want to replace a limb with a gun or a sword, ie. Evil Dead/Grindhouse style. I'm thinking of using Cinema 4d, would that be the best way to do it?
 
You'll need to be pretty precise with things like tracking and match moving.

I did a music video with extensive greenscreening with the T2i. It's not easy; the aliasing really shows up when you pull a key and you can end up with many layers of footage with holdout mattes and lots of hand tuning for even a simple shot. For keying on a budget, the HMC150 for instance is a massive improvement in my experience. With Canon footage, smoke and blur are your friends in shot design.

I'm hoping to comp some actors into a model set using green-screen (Actually I may have to use blue as there are green glass elements in the set). Is this do-able with a 550D or should I try to borrow the Canon XF100 that I'm trying to persuade my school to buy?

The best kind of even lighting for Green Screen is to use a soft box. Light your background first + evenly, then light your subject separately & make sure they have space from the background. A good rule is at least 5ft of separation.

This is also dependent if you use Chroma-Green or Digital Green.

Digital Green is much more reflective, so if possible double that!!!! Otherwise, you have "green halo's" on everyone.

Totally which is why I said at least 5 ft..... Honestly though it's really about lighting , just like anything. I recently seen this Movie on Dvd 'Faster' http://www.amazon.com/Faster-Dwayne-Johnson/dp/B0034G4OUO/ref=sr_1_1?ie=UTF8&qid=1307307585&sr=8-1

& thought the cinematography and lighting was amazing, if anyone has a chance I suggest them to check it out, truly inspiring.
 
It just occurred to me. I don't know what camera you're using, but in terms of sensor size, the 7D is perfect. The biggest downside is the AVC compression. I wonder if recording the 1080p signal output would serve green screen recording. You do have the red dot up in the corner, but that's easy to remove if you're going to be keying out the green anyway.

Nah, there are all sorts of problems with recording the hdmi signal out. If I recall correctly, it is not all that clean either.
