Overexposure Correction help needed!

Alright, so I was taking studio pictures for my skate team. We have a softbox, and an overhead light, and shooting on a Nikon D90.
I edited the first two skaters after the team went home, and they came out exactly how I wanted them.
When I got to my third skater, I suppose he was standing a tad closer to the softbox. The raw photograph looked no different then the rest of the team, so I didn't put much thought into him being a little closer. Although, when I began editing, his left cheek easily gets washed out during the procedure to get each picture looking similar. When I try to fix it, his skin becomes discolored, or gets cloudy looking. What can I do to fix this?

(I'm using Photoshop CS6)

Looking for some advice on a good camera for a beginner?

I've decided I want to buy a good digital camera. I'd like to take a few photography courses just to be able to take better pictures (not to become a professional). The types of pictures I would be taking are mostly of people or buildings/scenery. For example my boyfriend and I are going to Disney World next month so I would be taking pictures of him and other friends as well as taking a lot of pictures of the various sights. The most important thing for me is the clarity of the picture. I hate when I take pictures that are blurry or look really pixelated like I took the photo in a basement in the 70s or something. I just want my pictures to look like they're HD quality. I know that to achieve that I not only need a good camera but also need to be a better photographer so I will work on that but I would love some advice on what kind of camera would make that easier for me. I'd also prefer a camera that's not extremely heavy.My budget is between $600-$900 and I think I would prefer Nikon or Canon but I'm open to all suggestions. I really appreciate any help you can offer, thanks so much!

Why does my Nikon 1 J1 camera stop recording automatically?

I have a SanDisk Ultra card with 32 GB. I have no pictures or videos on my memory card.It stops recording automatically and it says "processing video" or something like that when it stops.It is so irritating and I just bought it! I loved the camera until this problem came up. Please tell me that there is something I can do to fix this!

It also says that I can record for 20 minutes, but it stops after 1 minute or something like that!

Expensive camera with cheap lens, or cheaper camera with a more expensive lens?

Hey, I'm looking at either getting a Nikon 5100 with the stock lens, or getting an older Nikon D3000 with the stock lens, and probably some other lenses, such as a 50mm. Which do you think would be a better decision, a D5100 with one lens, or a D3000 with a few lenses. Thanks :)
Added (1). The D5100 is about $600
The D3000 is about $300
And the lens I want to include with the D3000 is about $150.

Are there lenses to help the nikon d800 with low lighting?

I'm trying to decide if i want to get the canon 5d mark iii or the nikon d800.i know that the 5d is more versatile (being better with low lighting and aliasing) but the d800 has an overall better resolution (therefor better images). also the footage of the d800 doesn't have to have a lot of post op work on it (5d needs it every time if you want your footage to look its best).so I'm partial to the d800, but are there lenses that can help with its low lighting or aliasing problems?

AI-S Lenses on the Nikon D3100?

Is it possible to mount and use AI-S mount lenses on the Nikon D3100? I understand that it will not be able to auto-focus or meter. I want to buy the Rokinon MC 28-80mm f/3.5 to 4.5 and the Sirius Auto Zoom 70-210 f/4-5.6. I have read that all AI-S lenses can be mounted on the D3100 however on the 28-80mm's webpage it states that this lens cannot work on the D3100. Can I use these 2 lenses on the D3100?

Taking football pictures with a Nikon D3000 at night?

I have a Nikon D3000 with a Tamron 70-200 f/2/8 lens that I use for sports, I am relatively new at it only have been taking sports pictures for a couple of years. I want to know what would be the best setting to use for night football games. This is little league and I am still working on getting permission to be back down on the sidelines again this year. I did most of their baseball games over the summer but they only have a few under the lights and only one with my new lens (the others I used my kit lens) I had a hard time because I felt like to got the setting right then he would move a few feet one way or the other and it would be messed up again. The reason I ask is one of them will have more games under the lights this year, last year all his games were during the day. Oh and about half way through the season I started shooting in Manual so that is all I shoot in now. Thank you for your suggestions.

Nikon d600/ Canon 70d & 7d mark ii?

The Nikon IS real, but are the Canon dslrs actually coming out or are these just what people want, cause they're all over "canonrumors.com". And of so, when are they coming out? Canon has released the Pro 1dx and the 5d mark iii. For the entry level they have the (t4i/650d). When are the new midranged cameras coming out? People were saying August of 2011 to be announced but it's now August of 2012 and still no announcements! I'm looking to get a entry level full frame like the d600 and supposably the 7d mark ii.

Anyone ever bought from Lensa Grafita before?

Okay, so I looked on here before posting this for similar questions and there was only one. I'm wanting a Nikon D5100 SLR and the cheapest place I could find one was Lensa Grafita -I don't have a lot of money at all and this is the camera I have been looking for for a long time now to get one cheap- It says that this camera is on sale, with the lens and other accessories. The only thing that makes me wary is the fact that they only accept bank transfers… Never done that before, -always use Paypal- I would like to know if anyone has used them before and if they can be trusted or any other advice given would be nice.

I don't want any 'avoid!!!'s' okkay? I would like proper advice!

DLSR Backpack for climbing half dome?

I am going to be climbing Half Dome in Yosemite in the Spring and I am looking for a good DSLR backpack. I will be carrying my Nikon D90 with the 18-105 mm kit lens, an extra 55-300 mm lens, and an extra battery. I will also need room to carry a little food (my husband can carry most of that) water, and a light rain coat just in case. I was thinking something with a laptop section would work and I could slip in a hydration pack ( i'll make sure to take waterproofing precautions). I was looking at the Tamrac Adventure 9 online. I am 5'2 and 120 lbs though I was wondering if that pack would be too big for me to climb half dome with for my first time. Anyone out there with that bag? Or any other suggestions?
