Spotted Salmander development timelapse

Post by Zach Cava » May 17th, 2015, 5:55 pm

Been busy with grad school and haven't had time to post here lately, but here's a fun project I've been working on these last few weeks—best viewed in HD!

Good golly Miss Molly! That is one of the coolest things I've seen in a long time!! I've no idea how you go about doing something like that, but kudos to you :beer: . And it's almost as if the embryo is "dancing" in time to the music. BRAVO!

Very cool Zach! Thank you for sharing. I'm very impressed with the clarity and stability of the video. We shot photographs of our developing tigers but the image quality was much more pixelated and video took too much memory to store. What kind of mount did you use on your scope?

Are you doing IVF or cryo? We were always excited to reach neurula after an IVF with cryopreserved sperm, especially since post thaw motility tended to be 20-30%.

Keep up the great work!

Thank you guys

Hadar, I actually didn't use a microscope for this, I used a 100mm macro lens + 68mm extension tubes. Eggs were in a modified tank I built for photographing aquatic stuff (can post photo later), but I was thinking it would have been easier/more stable with a scope + camera adapter!

It seems like a lot of the issues with video quality have to do with how you process the video. I don't have any experience with video editing and it took a lot of trial and error to get a decent quality clip uploaded, and I'm sure there are ways to get it to look even better that I just haven't figured out.

I should have mentioned that this is just for fun — for my graduate thesis I am studying hellbenders.
