#383247 Exploring the Salish Sea

Posted by GeoPaul7 on 17 April 2017 - 08:12 AM

A video compilation of diving the Salish Sea during the winter. I tried labeling the critters for identification purposes. Comments & critiques are welcome.

 

 

Wow!   Superb.  Love all elements including music.  And I love those moving captions!  Incredible macro!

 

Thanks for posting.

Last work at Red Sea...

 

 

Thanks for posting Alfredo!  As I mentioned on my comment on the Vimeo posting, I very much like the way the video lights illuminated the golden fish in the foreground.  Nice work!

Yes thanks for sharing.  I did not know that there were such sites there.  So much more colorful than one would expect!




#380499 Nudibranch - Polycera

Here is a clip of some Polycera quadrilineata nudis i have filmed recently.

That is cool.  I noticed the spectacular lighting as well.  Is that snoot?

I have started to do "bite sized" films in going through my Raja footage.  Otherwise I would be overwhelmed.  I will make medium sized and large as well, but those take time and it takes much less time to edit a film on a specific subject.

 

I am giving people here the link of a film about a damselfish with a remarkable behavior.  It is  Dascyllus reticulatus.  It lives in branching coral, including spectacular specimens of table top coral.  Here, I think the species is Acropora pulchra, but I may be wrong about that one.  I filmed some Dascyllus in the Misool area in a couple of different locations.  

 

How many of you have seen this wonderful species?

That appears to be an impressive monitor.  I like how much "real estate" you have there.  What monitor is it?

 

Yes I need to get a nice big monitor like that.  I do all my editing on my 15inch MacBook Pro.  I still have not seen any of my films in 4K yet!

Thanks for posting.  Its probably worth preparing a 8-10 min summary cut to get across his key messages. I don't think you will find many people listening thru a 45min interview.

 

In the cut maybe you blend in your questions as you are hard to understand even with volume fully up. Blending in your question on a black background and then moving back to Andrew while he is responding adds a bit of 'activity' as well.  I'd also think about inserting some of your dive footage while he talks (for example while he talks bout Magic mountain, show some of your Manta clips form that spot. Inserting a photo or clip of the resort itself here and there might also add depth. It all makes it easier and more attractive to keep the attention of your viewers.  Just some ideas....

 

And BTW: I think Andrew's last name is Miners (with an "s" at the end).  At least that's what their webpage suggests...

 

Bubffm:

 

Thanks for these suggestions.  I am planning on doing many of these things, for precisely the reasons you suggest.  I see this footage being used in at least 2 other films. The key is to make things as digestible and understandable as possible, and people certainly can't pay attention that long -- unless they are doing research. 

 

I did, however, want to post a completely unedited version of this interview, which I consider an important interview.  I see this film as having historical interest, so wanted people to be able to refer to the interview in an unedited, unabridged way --  as a "primary source." In addition, I think Mr. Miners and Misool will want to have an unedited version for their own purposes.  Hopefully they can download from Vimeo.  Can they do that?

 

I will be doing the sort of edits that you recommend -- making this digestible and much more colorful.

 

And yes I have a typo in the film about Andrew's last name.  I am uploading a corrected version and it should be ready in an hour or so.

 

Thanks for your very helpful feedback.  I will keep posting things to our site here, to get more helpful ideas.

Where did you do this interview ???

This was in his office, at the Misool EcoResort.

Ok guys.  I just posted the first little film from my Raja trip.  All this footage was shot at the same dive site -- the "Magic Mountain" that Ammar and I visited.  I was following the advice of several people on this topic.  I shot this exclusively with UAWB, and video lights when I could.

 

I started off using manual exposure control, and could get great results, but I was constantly having to adjust exposure.  When you are an ambient light photographer "running and gunning" on a dive like this, it really helps to use auto exposure, as every time you change the view, the exposure can change.  For example, capturing a scene shot into the light, or with the sun in the frame like many of these shots, is quite different from what you might do if you merely turned around and shot the other way.  Thus, I got passable results using auto ISO underexposed .7 stops, usually. 

 

This was shot with the a7s II.  I think the low light capability of the camera really makes it helpful in shooting ambient light.  Next, the waters varied from murky, to a little less murky, and were never anywhere as clear as either Grand Cayman, or Cozumel.  (This is one reason why there are 100 times more fish).  I think it also very much helped the white balance issues, which pop up when the water is too blue and clear.  Thus, AUWB works better in murky water, when you use video lights in particular.

4K on Vimeo.  Alfredo!  Thanks for uploading in 4K.  I have noticed that VIMEO is now streaming 4K more often and better and better.  If you choose the option, all you need to do is let it load a little, and then you can indeed watch in 4K -- although it is doubtful your screen can handle that.  Of course you need a good internet connection.

 

Great job Alfredo!

Well much better w lights. When did you shoot ? Morning, miday or afternoon ?.

 

These were shot in the morning. One thing that I have noticed is that the lighting above water, and particularly the direction of the sun, make a huge difference.

TaxiDiver:  

 

On the test movie I supplied both RAW and Corrected, one after the other, so that people could compare.  I did that with 2 clips, so you will see 4 clips in the little movie -- two versions of each file.

Thanks to you two for posting.  I appreciate it and will digest your posts, and films, and respond.  Since Taxidiver was kind enough to post his films, I thought I would throw together some of the recent 4K footage shot in the Gulf of California.  I show two clips twice to illustrate a comparison of Raw footage and some post processing (not touting it, just showing you how footage shot without a picture profile can be edited for color correction in Premiere Pro).

 

Ammar:  You comprehensive post is awesome.  In particular I would like to get back to you on the picture profile issue.

 

 

Thanks,

UPDATE TO ALL:

 

I am back from my Sea of Cortez trip and here are the results.

 

1.  Yes I was trying too many things, as Taxi Driver said.  Thus, I did not experiment with picture profiles.  Shot with no picture profile for video and this also facilitates the use of the camera for RAW still photography.

 

2.  I was never able to achieve  a custom white balance.   I tried a white slate, my hand, the white sand, and at about 30 feet, where I was experimenting, it always came back "White balance error."  This is as Dustin says.  And this is not what the expert at Backscater said.  He advised me to always take a custom white balance with this camera, and in Cozumel, I was following his advice pretty strictly, and it was yielding the poor results that are apparent in my first test film, which showed all my dirty laundry for the world to see. On this trip, in the Sea of Cortez (where the water was a different color and the temperature was 86 degrees)  I was using a magic filter, and then I tried automatic underwater white balance, and things turned out exactly as Dreifish says.  Sometimes the colors were awesome, and sometimes terribile, and sometimes things switched in mid stream.  It did depend on the lighting conditions at the time.  I will post some of the results.  We were also experimenting with a GoPro using the Backscatter filters, and it is interesting indeed to see the way the white balance is handled on the GoPro as compared to the Sony.

 

3.  Light gathering ability.  The main thing I noticed was the awesome light gathering ability of the Sony a7s II was evident.  I was able to get passable results, using available light only, even at 30 or 40 feet.  The professionals who always use bright strobes, for perfect white balance and huge depth of field, would not be impressed.  However, it never looks like that in reality.  It is an artificial way to see things. I rather liked seeing things as they actually are, with the light filtering through the water and a bit of a shadow from the point source of the sun, rather than a completely diffused light source like a strobe illuminating a macro subject.  Still, even there with the available light, I was using a  magic filter and the auto underwater white balance.  

 

Next trip, in 3 weeks, I will see if the camera can handle things without a magic filter, using the underwater auto white balance.  This would allow me to use video lights and ambient light on the same dive.  Not supposed to be able to do that, but perhaps that statement only applies to custom white balance. Maybe not to auto underwater white balance.  My bet, however, is you still have to use the filter. 

 

Again, thank you for everyone's responses.  I am working on a film that will illustrate my experiences, as well as tell the story of your typical dive trip out of Phoenix, Arizona, with all the various and sundry characters, shady and wealthy and grown up and kids, all thrown together suddenly for a diving adventure.
