A visit to Byrne Creek Ravine Park, Burnaby - BC.

Byrne Creek, close do Edmonton Sky train.

A quick day wet day out in Byrne Creek, Burnaby - BC.

 The idea was to find the Salmons…but muddy water and bad rain didn’t let it happen ;)

 Next time , maybe..

A very health river running from Edmonton Sky train up Marine Dr.

You can find a nice spot for the Salmons:  at 6162 Portland Street, Burnaby, BC V5J 2S2

The closest I’ve got to my fellow friends..



Cross Polarized photography

” Every day is a school day ”

I’ve heard about cross polarized light some time ago. I knew the results of it over plastic stuff, the cool colours and etc. And thought I knew more or less all about it….silly guy.


 Back home, in Brazil, was just impossible to get a sheet of polarized film sheet. But in Vancouver they are supper accessible, and during one of my studio times, decided to give it a go.

  • I knew: Polarized lighting —- object ——> Pola filter = Cool picture. That was my knowledge.

 I decided to try it with a shine metal object, sure that I would get all those crazy LDS colours over it.  In a white background! Silly again.

I didn;t know, but I was trying to light the key with the polarized lighting; which is very different from thing, considering that I was looking for the colours..

 

After moving lights and lighting angles, I’ve got it. Suddenly, the silver key became BLUE!  You can really sees it, but the camera does! I you’re wearing polarized glasses, you  can  see it.

Playing around and moving filter..and than the silver, blue key, turned BLACK! Jet black. And that stayed in my mind…

Doing some research, I’ve found this  LINK

 Where I found thins intriguing image:

More googling and ended up finding a bunch of images with some crazy lighting. The pictures were on Shuterstock, and with a uncommon keyword #polarizedlight

Seems that the lighting block all the shines and reflections of macro pictures; and adding lots of texture to it! 

So, could I make the background jet black, the same way I did with the key?!

Decided to try!


It’s funny that what happens is the background it totally independent from what happens in the ” surface”!

Let see what I can make out of this =D

 News coming up!!!

Try to turn this into LSD crazy stuff

ops! something going on around here.

 UPDATE!

 And nature keeps amazing me!

 Mother nature knows this stuff for ages..and that’s one of the reasons why some fish are SILVER!

Science and Photography

It’s been a long a ago since I first thought in a way to work my background, in biology sciences and my work as a photographer.

Brain at work!

Living in Brazil leaves you very short options, since full time wildlife photography is more an exception than a possibility for a young professional. Using photography as a tool is very common and there would be no chance of me finding the holly Graal with a picture…

Some decapod at Petar State Park, Brazil

Than I turned my attention to what researchers were doing in means of photography. Are they any good? It’s it just for a documentary purpose? What’s is going on?

My last time with a researcher I could understand some of the needs and frustrations. The task of shooting his collection was  ” so huge” that he could even imagine it happening…

Fishes are my main interest  in biology so, I was clear about what would be my focus. As a fan of scientific papers, I could understand where the pictures published could be improved.

Working in one of the first essays: “life” fish stack photography.

 That’s where ”  Updated on live specimens photography, using digital technology ” was born =D

 It was my first time working in a scientific work, and my goal was to set a standard for shooting live fish, with digital technology (there were some publications from the 90’s, mainly dealing with film photography - very useless for today’s conditions).

Took me sometime to really start working. And for sure this guy was an 

inspiration:  Levon Biss.


diagrams…

and more diagrams..

This was when I started: look the lack of focus, due the deept of field.

problem solved =D

After 4 months, the manuscript was ready, thanks by the help of some friends and collegues.

The whole thing was submited to a Zoology Journal and hope they take the bait!  =)

Here follows de abstract and the refferences:



Abstract: An updated in the fish tank photography is presented, with improved techniques, based on previous articles. A flexible system for photographing without shadows is suggested, in field and under controlled lighting situations.

A method for photographic improvement in live fish sharpness is suggested and the results discussed.
