I know this was posted seven months ago, but I'm in the market and can clarify a few things.
Fox (KDFW) shoots on P2; NBC (KXAS) shoots on P2; CW (KDAF) shoots on Sony EX. I can't remember what CBS (KTVT) and ABC (WFAA) shoot on.
The stuff you read about the pay above is accurate. Fox is a union O&O, so the pay is good. It also means the new shooter is at the bottom of the pile when it comes to vacation time, scheduling, equipment, etc.
WFAA is a Gannett station, pays at the lower end of the market, that's because it's a destination shop (it used to be). They still do good stuff, but honestly the daily stuff is almost identical across the market. They also have their go-to shooters/editors for their big pieces, so you would likely be on daily assignments.
CBS is an O&O shop, pay is okay. CBS is also in Fort Worth, the other stations are either in the middle of the market or in Dallas. That may affect where you would live. People I know there are on both sides of the happiness meter. Some are really happy, some are waiting for a better opportunity.
CW hires preditors, not shooters. If you worked there, you wouldn't be doing what you're probably doing now. Then you'd probably go find a nice PR firm to work for. There are some good people at CW, it's just stuck in the bad programming/Tribune ownership trap. Pays better than WFAA, but it's not shooting/editing news like you'd probably be used to.
NBC is an O&O shop. Pay is on the higher end of the market, based on experience. They have regional VJs (based in specific cities) and they also have a news staff of shooters/editors and reporters. I know they have probably 20 photogs and the average tenure at the shop is 10-15 years. I know some guys have been there more than 20 years.
Also consider it's not a market you just happen upon, there are a lot of small markets in Texas and CPs, Ops Managers, and NDs all get a lot of tapes (or links) from people waiting for a slot to open up. It would be worthwhile to figure out what sort of shooting/editing you're best suited for and make a contact at that shop. Also - there are network bureaus in Dallas with network positions (if you don't mind travel). There is also Fox Sports, and production shops for the Dallas Cowboys, Dallas Mavericks, Dallas Stars, and Texas Rangers. Point is, there are a lot of shooting/editing jobs in the market outside of traditional news.
