Hi All,
Question on the same topic.
Do you guys out there use AV/ TV or manual exposure when photographing birds (both on flight and still)
thanks

By far, AV is the most commonly used mode. TV is rarely used except for special occasions where for example, you want to blur the wings with slow shutter speed.
But AV mode can get fooled easily with changing background and lighting as you pan to track a bird. In these situations, manual exposure can be handy although it is difficult to master. You should turn on the histogram, and shoot in the brightest place and make sure the graph doesn't hit the righthand side (i.e. you have "clipped"). Also, turn on highlight warning. This will cause the LCD to blink the pixels which have clipped. You must make sure nothing blinks as once you have clipped a pixel, there is nothing you can do to rescue it. However, if you underexpose, within reason, you can still fix it in Photoshop.
The other thing to learn to use is the exposure compensation. That is the big wheel on the back. Shoot an image and if you are clipping, simply rotate the wheel (after pushing the shutter button half way), toward the negative side (i.e. reduction of exposure). Do this until you stop clipping. This way, you are still in "automatic" mode should the situation change and still have a shot at decent exposure. With manual mode, if you don't change the settings manually, you may completely blow the exposure.
In summary, AV means exposure is correct most of the time. Manual mode means exposure is correct all the time if you manually adjust it all the time. TV mode is rarely used for wildlife work (or for that matter, most other kind of shooting).
