Another good place to get pictures of bats is by water.  Bats skim long ponds to drink, If you have such a pond (natural or artificial) in your area that allows good bat access, that might be a good place to wait. 

You guys are lucky to have bats in your area.  Sadly, in my area bats are becoming a rairity.  :'(

One of my better attempts.  Taken with a 1Ds Mkii, ISO 400, with a 135/2 lens and flash.  My camera isn't ideal for this.  It focuses fine, but struggles with noise at higher ISOs.

Hmm. Forgive me...because my analytical mind just has to make sure here...but...why does the bat have a close, dark, sharply refined "drop" shadow? Isn't it the sky behind it...at....a very, very, very great distance that wouldn't actually allow a sharply defined shadow so close to the creature.......if it allowed a shadow to show up at all..................?


...I just hate to say it....but...without a VERY good explanation of the shadow....I'm calling bull!  ::)

It was shot at 1/160s with rear shutter curtain synch.  The rear drop shadow is the movement of the flying fox before the flash kicked in.  But that's the sort of problems I'm trying to work around.  If I shoot at faster speeds, I can avoid this, but then I lose detail in the sky and if I shoot faster that 1/250s then I'm also stuck with HSS, and the bats are too far away for this to work effectively with the gear that I have.  To counter that, I can increase ISO and decrease flash power, but increasing ISO results in more noise.  Its hard to get the balance right.

Hmm. I guess that's a plausible explanation. Based on the actual offset of the shadow, it was moving at a vector of about 120° then...as the shadow is not directly behind, it's offset to a about a -35° angle. That seems a little odd...but, eh.

I think you could crank the ISO up more. The 1Ds II isn't that bad...it's certainly better than the 7D, despite being older, and the 7D is pretty good up to ISO 800. Also, that is indeed how clear and sharp the bats are after the flash, then that means they are easy to mask. With masking, you could clean the background noise right up! You might even want to look into PixInsight, which has some of the most advanced multi-scale noise reduction tools around, but Photoshop or LR could certainly do it as well, I mean you could completely obliterate the noise once you have the bat masked. If that's the real problem, and that shadow really is caused by flash lag with rear-curtain, then I think you could crank ISO by at least a stop, if not two, and use two stops faster shutter speed.

Here is my contribution to bats in flight. Caught this cutie near a small pond at around sunset. His flight was so fast and erratic it was very difficult to track.

60D - 100-400mm, at 190 mm, ISO 125, f5.6, 1/1000 (shutter priority)

Hi Islander.
I have watched bats in flight and concluded they would be impossible to track, if you only think it was difficult your technique must be several orders of magnitude better than mine! Congrats on this shot, getting one in frame must be very rewarding indeed.

Cheers Graham.

And then, of course, you have camera shake, wings flapping etc etc.  Another one without any shadows...

I jus gotta say that these are some awesome bat shots.

You guys might want to contact Bat World and see if they would be interested in some of these fantastic shots.
