Nikon D3100 (brand new) or Nikon D90 (2nd hand)?
My budget is tight on these two choices so if anyone could help me out on which is a better choice between the two?

So I have a Nikon D5000 at the moment.
And but I want to know what the best settings are.
*I'm not a photographer. And I don't plan on being one.
I'm just a noob with a camera. So could anyone help me out?

How to turn a movie file into a GIF?
I took video on my camera (Nikon D5000) and I'd like to turn that video into a GIF file that runs on a constant loop. Sort of like a time lapse. The video in specific is a sunset sort of thing and it's about 15 minutes long, but I'd like to condense and speed it up, and set it on a constant dark-bright-dark-bright sort of thing. Does anyone know how I can do this?

Which would you suggest Point and Shoot or Camcorder?
I already own a Nikon D60. I'm looking for a camera that has good resolution and zoom for great pictures in a more compact camera. I'm also looking for a camera/camcorder to record videos for youtube but I'm look at a price range of about $200 or less. I know there are good point and shoot cameras that also shoot HD video but would I just be better off looking at camcorders?

Auto Focus built in. Canon/Nikon, 3rd party lenses?
I want a new entry level cheap dslr.
Canon 1100d or Nikon d3100
So, the deciding factor for me is, that Canon has AF built in and Nikon doesn't.
I can't afford either canon or nikon lenses, so I will be purchasing Sigma, Tamron etc.
So, if I wanted the Tamron SP 60mm F/2 Macro, will it work the same or similarly on the two cameras? Does the built in AF on the Canon change anything?
What if I wanted the Tamron telephoto 55-200mm?

Nikon d40x camera lenses? What will work with autofocus?

Wedding photography advice and tips?
I'm new to photography, I recently purchased an entry level Nikon DSLR as an upgrade to my Nikon N55 and N65 and I've been shooting like crazy mostly family and some nature shoots and posting them up on my FB page. A couple weeks i got a call from a friend who's mom is getting married at the end of the month and she asked me if i could assist her as a second photographer keep in mind this is also her first weeding and I've been doing photography a bit longer then her but never a big event like this.
Any advice/tips you might have will help a lot i already watched all the youtube videos i could find lol and i feel pretty confident about it but really any advice will help.
i'm not charging her for my time there or editing of the photographs and she will get a photo CD and i might also create an album for her as a gift but in no way will i accept monetary compensation.
Thank you for taking the time to read all these.
