Are you one of those that's not nailing exposure with your D700?, I certainly am, but now that I've found UniWB for the D700, things are shaping up. This is a great and simple tool to get real control over your exposure, and to really use the histogram as intended.

So what is Uniwb?, well, it is very simple. It is a NEF-file set to be neutral by using a WB preset in your camera. This preset will always have a neutral histogram, in any light condition. So it is easy to judge correct exposure using the camera histogram.

UniWB is for people shooting RAW, believe me, you would not want the white balance that UniWB uses on all your JPG's (Cyan/green/beige/orange-ish, horrible actually), but if you shoot RAW, you will benefit tremendously by shooting with the UniWB set in your D700, and it's easy to set WB in post anyways, so this is a win-win situation for the RAW-shooter.

You can get the UniWB file here. You than need to copy that file to your camera, here's the procedure:

1. Download the file
2. Rename the file to _DSC0001.NEF
3. Copy it to your CF-card (into the 'Playback'-folder, root of CF-card won't work unless you configure the playback folder to 'ALL')
4. Insert the card into your D700

Now you need to copy the WB-information from the UniWB file into a preset in your D700. Use this procedure:

1. Go into the Shooting menu, select 'White Balance -> PRE Preset Manual' and press Right on the multi selector
2. Select a preset bank (I use d-1) and press the center button of the multi selector
3. Go down to 'Select image', and choose the image you just downloaded

Almost done. You now need to set the camera to PRE and d-1 (or any of the d-1 to d-4) white balance preset banks. So press and hold the WB-button and dial in PRE, still holding the WB-button set the front dial to the 'd-1 to d-4' bank you copied the UniWB to.

There you go, now you can shoot photographs with fine control over your exposure. You could take it a bit further by zero out Picture Styles, the more neutral the better.

Hope this helps you in your quest for better exposure.

I big thank you to Iliah Borg for creating the D700 UniWB file.
