Which DSLR is best for video? - 1

I'm looking to buy a new camera and i have decided that i want a DSLR. One of the main reasons i want a DSLR is for video, i don't want a video camera since i would still like to be able to take fantastic photos.

I've been looking at a few cameras, such as the Canon 7D, Canon 60D, Canon 650D, Nikon D7000 and possibly the new Canon 700D.
And a Sigma 30mm lens

Are any of these cameras better than each other? Do you have any suggestions?

Photography. How do I use an external flash?

So, I'm doing a school project, and I'm using an external flash. A vivitar 283 flash, to be precise. And, the teacher has not told us anything on how to use it, or what to do. Just, put it in the shoe, and start shooting. Now, I've looked everywhere on the internet, for how to use it, or how to use any external flash. I've had no luck. I also tried experimenting with it myself. And, that, unfortunately, didn't work. All of my pictures turned out completely white. Even when I turned the shutter speed up higher, to capture less light. That still didn't work. I turned the aperture down, and THAT didn't work. They still all turn out too white. I don't know what I'm doing wrong. I've also checked in the settings of the camera. It's a Nikon D3100.So, someone, please help me. I feel all alone!

How to photograph the May 10th solar eclipse?

I have a nikon d3000 with a 70-300MM lense and tripod. I was wondering how i would take a picture of the eclipse and at what settings. Also do i need a Solar filter, some people say yes and some say no. I won't be looking at the eclipse directly. I will be setting up the camera before hand, put on shades then using a remote to snap a few pictures. Would that be possible, will it damage my camera?
What settings should i use on the nikon. Manual mode, Wiat iso, fstop and shutter speed am i looking around?

Main differences between Nikon lenses // 55-300mm - 70-300mm?

I'm trying to decide between these two lenses to use with my nikon D5100.It would be used for various things from portraits of people, animals, a few outdoor animal action shots (nothing super amazing, just of my own animals) landscapes e.t.c. Just for my own enjoyment.

I know that there's quite a price difference between them, and from what i have read i'm thinking of going for the 70-300 lens, but is the extra cost worth choosing this one over the 55-300? What are the main differences between the two? I currently only have the 18-55 that came with my camera. Any info and advice hugely appreciated.

My yong rf-603n triggers are not firing my b400?

Need some guidance in dumb downed terms. I'm brand new to mono lights and have my old yongnuo triggers that'd I used to fire my yongnuo flash. I ordered and received my alien bees b400 and am now trying to fire it but the triggers don't seem to be working. The pc sync cord that the light came with isn't comparable with my Nikon d3200 so I can't simply just use that. I have the trigger on my hot shoe mount and it is connected to my camera. I understand that the light is built with an in sync motor to pick up most transmitters so I'm confused as o why its not working. Any help is appreciated.tgankyou!

Picture Resolution for Nikon D5100?

I have a Nikon D5100 DSLR camera. When I compare the image specs between pictures I took a month ago and pictures I took just today, I noticed the following difference:

- Pictures taken a month ago: 4737 pixels x 3158 pixels, 789 dpi
- Pictures taken today: 4737 pixels x 3158 pixels, 300 dpi

The image quality settings have never been changed - They have always been set to "fine".

Are the image resolution the same for both pictures? The number of pixels seems the same, but dpi (dot per inch) is different. Why is that?
