Hi guys I am looking for a little starter advice for my new SB-700 and my D5100. I just bought the SB-700 and I am not sure what setting I need to use just to get started I’m trying the TTL method first till I get more familiar with the flash gun. I see that as soon as turn both the camera and flash gun on my camera sets the shutter speed to 1/60 I understand from the manual is correct. I am using a Nikon 18 to 105 mm lens and I am not sure what aperture to use I have tried 3.5 and 5.6 I am indoors in a normal lit room, I have the ISO set at 100. I am also bouncing the flash off the roof. But all my photos are quite dark, so I have added +2 EV on the flash and now the photos are a lot better. So is this normal to have to do this EV compensation or have I missed something in the manual. Also on the flash guns screen it sometimes says TTL and sometimes TTL BL I think the TTL BL is a balanced light and I don’t know the difference with TTL and I-TTL is and can I use I-TTL on the D5100 Please don’t say read the manual as I have read it over and over again and I’m still confused.

I am definitely not an expert at indoor flash, but I think there are several possibilities that could be causing (or contributing to) your issue. A little more information would probably help us analyze the issue and give better responses: 1. How high is the ceiling and what color? Are there any obstructions that could prevent the light from reaching the ceiling, or prevent it from reaching the subject? The higher the ceiling and the darker its color, the less light will reach your subject. Also, if something is obstructing part of the light (a dark beam across the ceiling?) less light will reach the subject. 2. How far away is your subject? 3. After a shot, does the flash-ready light blink for a couple of seconds? If so, this indicates the flash has used its full power but still couldn't reach a "normal" exposure level. However, since you were able to get better results by adding +2 flash exposure compensation that seems to be an indication that there was some unused power remaining in the flash. 4. In what metering mode is the camera set?
Just as a general point, ISO 100 may be a bit low for bounce flash with a relatively slow lens such as yours - especially if there are any other circumstances that could be reducing the light reaching the subject (such as bounce distance, surface color, obstructing objects, etc.). I use an f/2.8 lens for most of my indoor bounce flash shots and I still set the camera at ISO 200. At f/4 or f/5.6 you may get better results with ISO 400 or so.
There are probably other things to ask or think about, but this is what I came up with off the top of my head.

The SB-700 has a built-in bounce card, have you tried that?
The SB-700 also has a diffuser dome that can soften the flash.
What meter setting are you using?
Do not have Auto ISO turned on. You want a fixed ISO value and the same ISO value to be used for the ambient light exposure and the flash exposure as the camera will compute both and use both for the final exposure since both occur when the shutter opens.
TTL is "Through The Lens" for measuring the flash exposure on film cameras while the shutter is open and not used by dSLRs. iTTL is "intelligent Through The Lens" and uses pre-flashes to measure the flash exposure and compute the needed exposure for the flash before the shutter is opened and is used by the newer professional film SLRs and all CLS compatible dSLRs. This exposure is separate from the camera's exposure. The Speedlight show TTL when it is in the iTTL mode because of the limited LCD screen size and the amount of data to display.

The 1/60 is the slowest sync speed and used for flash bulbs. Your camera should be able to sync up to 1/250 of second.
