I'm not even going to post the link to the old video, I am just going to wait for more of your work!
Oh, and I must say that Nocomis rule!

Michael, thanks. Yeah there was quite a learning curve, and it needs re-learned each year, but I think I have it down now. You see, I'm shooting most of this blind. I'm just guessing where the fish is. If it's really overcast, I can see the reflection of the player in the mirror thingie, but that's really only when I'm in shallow water, and the colors suck. Like that ashy darter I post the other day... Totally blind. I was hanging from a rock and was holding the camera straight down just hoping to get the shot.
Most of the time, it fails miserably (I don't even want to think about the awesome footage I blew at my Aunt & Uncles new cottage last year). But when filming our gaudy friends from subgenus Nothonotus, it typically works well because they have such high site fidelity and they're on the bottom, so the camera doesn't focus on detritus in front of the housing, for example. I also had to figure out how to keep it from fogging up (Sea Drops and a maxi pad believe it or not) and then after that, how to keep the Sea Drops from bulking up too much. The colder the water, the worse it is. And if you get a DROP of water in the housing, you're hosed. The camera heats up and turns it right into steam.
So yeah, that Conasauga footage was terrible (although I'm going to snag some of the Alabama shiner stuff again - I wish I wish I wish the housing hadn't fogged on the bronze darter spawning!). I also didn't know to stay in place (I only infrequently film the "Blair Fish Project" these days

I'm also very jealous of those of you who live with this clear water so close. Man, if I had only an hour or two drive, I'd have progressed a lot faster.
Anyway, I hope this inspires a whole gaggle of folks to explore the waters below with their eyes.
Edit: And yeah, I left all the extra in the redline intentionally. There's solid footage within that can be cropped for a more formal presentation, of course. But I wanted to show how effortlessly these fish live in THEIR habitats. If anyone ever again tells me a fish got "trapped" against a seine, I'm showing them this.

And I REALLY enjoyed the ashby darter footage from one of your other recent posts. I caught one a couple of year ago, dipnetting blind through vegetation, so I never saw it except in my net for a few seconds. Being able to see how they move and act in the environment is really neat.
Thanks for sharing, Todd.

I battled condensation problems for a while when I first got into UW photography. I tried things like silica desiccant packs and maxi pads before finally coming up with a real solution. As I’m sure you know, the whole issue has to do with water vapor in the air and the fact that warm air holds more moisture than cool air. When you fill your housing with warm air and then submerge it in cold water, the air inside the housing cools down, and the water vapor condenses and fogs up the housing.
The best solution to this problem is to limit the amount of moisture in the air inside the housing in the first place. You can do this by filling your housing with air from an air conditioner (air conditioners remove moisture from as well as cool the air). Just allow an air conditioner to blow cold air into your housing for a few minutes before you seal it up. You can even use your car’s air conditioner to do this. This works really well and you shouldn’t have any more trouble with condensation or have to use sea drops or maxi pads. The only downside is you can’t open your housing out in the field and then go back underwater unless you fill it up with cold air again.

Yeap, many times, if you're in the right places, you'll find juveniles living on cutbanks into gravel bars stabilized by Justicia. Is that where you found it? Cool stuff!
Issac, hey thanks, we can put you on them! They're not too far away from you.
That's an interesting idea. If it works with the car, on site, then I'll have to try it. However, I'm thinking that the video camera gets more hot than the cameras because it's always running and has moving parts etc... You aren't flashing right?
The thought that you could cool the air in the housing before leaving your house and get to a stream BEFORE it was back to ambient temperature makes me seriously jealous, man

Todd, your missing the point I think... it is not about the air being cool... it is about the air being dry... air conditioners dry the air as part of the cooling process... so what Isaac is saying is if you fill the housing with the dry air coming from an air conditioner, then no matter what the temperature is, there is no water (humidity) in the air to create the fog/condensation.That's an interesting idea.

Isaac, I really like that idea, it makes a lot of sense from a simple science standpoint... and is very interesting to me as I am buying some uw equipment myself to try out this spring. Thanks for the tip.

I see, I see. Okay, I'm gonna give that a try. It'll get the real test coming up in a few weeks with 55 degree water.

Thanks Micheal. That is exactly what I was just going to try to explain.

If you're referring to using strobes for my underwater photography, then no, I use only natural light.
