In Topic: 4K screen capture -> nudibranch eggs

kc_moses,

 

Thanks for the embedding - I was just coming back to learn how to do it.

 

The flickering is sunlight and waves ten feet above. I don't know what to do about that except maybe bring down an umbrella and use lights LOL I have lights but did not use them.

 

I was zoomed in, but not quite far enough as you can see from the vignetting. I'm in maximum learning mode as it was the very first time I've ever tried to use a diopter.

 

One thing that kept me from zooming more was the loss of focus if I zoomed in more. If I moved back a bit I might have done better - I'll try that next time. There's a pretty narrow depth of field with the +10, so distances are kind of touchy; a little more zoom, or a little more distance and things get out of focus in a hurry! I also have a +5 which hasn't been tried yet. Not to mention the surge...

 

Nudibranchs abound at "the bridge." If you look for Caribbean Sea Slugs at Amazon, you'll see there are quite a few there. One co-author is my source for the ID above. Not sure but I am under the impression there are more than 100 species of slugs and nudis at the bridge. More than 300 species of undersea critters have been documented there including seahorses, frogfish (we saw seven there last week) blennies of all descriptions and and and

 

I predict you'll like it!

In Topic: Red gel on underwater video light

01 March 2015 - 08:12 AM

Roger,

 

I second (or third) the idea that shooting with red light at night is problematic, so I've arrived at a compromise that I believe works more often than not.

 

I use red filters on my video lights, keeping them on low power while I am looking for critters. This seems to spook them less than the white lights.

 

I have previously white balanced with my lights on medium power (or whatever power I intend to use) without the filters.

 

When I find a subject, I remove or rotate the filters out of the way and do the shooting.

 

Whether this really helps, or just makes my life more complicated I couldn't say - I do think it helps sometimes.

In Topic: Lightroom 5 Corrupted Images

Adam,

 

I know my dive buddy used a Canon 7D (MK 1) at the time, and shoots exclusively RAW files. I'll see if she had the same problems with her E-M5 - can't recall.

 

Tom

 

PS: There was quite a range of cameras used by folks experiencing the problem; there didn't seem to be any common factor other than LR...

 

EDIT: I checked and she recalls both Canon 7D and Olympus E-M5 files being corrupted on the same PC using the same LR software. It was an equal-opportunity bug!
