Pro Photo Show & Beyond / PHOTOGRAPHICS Film
« on: June 03, 2013, 11:30:40 AM »
Gav here. So our new project just succeeded on Kickstarter and we'll be working on it throughout the Summer.

PHOTOGRAPHICS is going to be a workshop film like nothing you've seen. We're excited about this one.

Check it out here... Gav

It's here and it's long. Break it into two if you need to.

Gavin is out. Barry, Dennis and the crew has a party while he was gone ;)

Good job guys.

OI'm sure there some varied opinions. Let the discussion begin.

Listen here or on iTunes...

Lost of topics this month and a very long show. Plenty to break up into a couple segments. Share your opinions.

As for that title. You'll have to listen to the after show ;)

Light Zones and Beyond / Light Ratios
« on: April 14, 2012, 11:21:30 AM »
Light Ratios:

They represent difference between highlights and the shadows in a scene. It's amazing how many images are being made flat these days. Understanding simple ratios tells you a lot about your scene. It helps you control depth and shape and shadow. It helps you visualize and make an image work your way.

Lets imagine a face in a portrait, whether strobe lit or natural lit. Lets say you meter and light on the shadow side reads 1 stop darker than it does on the highlight side (you can even measure this with your in camera spot meter). This means double the light is reaching the highlight side, or a 2:1 ratio.

Anytime you increase or decrease by a stop, you double your light and thus your ratio.

A few highlight/shadow ratio examples…

1 stop diff = 2:1
1½ stop diff = 3:1
2 stop diff = 4:1
3 stop diff = 8:1

Now I certainly don't claim to be the grand master of ratios, I'm studying them further all the time. But at their core they are another simple powerful way for us to better work with and understand our light. We'll be looking at them further during my EXposed series...

There's certainly more to discuss on this topic. Lets do it...

Going Analog (NEW) / SOLD my first 4x5 Portrait.
« on: March 20, 2012, 11:51:19 AM »
I may have mentioned this in the past but I felt I should put it here in the analog forums.

I've been trying to take a couple 4x5 frames along with digital on each session I do. With this senior portrait last fall, I did just that and the final pick for the wall print was from the one color 4x5 I neg made. I sold it as a 40inch on canvas.

Going Analog (NEW) / 4x5 In Dark Areas.
« on: March 20, 2012, 11:41:10 AM »
I've spent the last three days roaming around Carlsbad Caverns. It's truly amazing. It's also incredibly hard to photograph well.

A film side challenge I found however was the low low. When using a view cam it's quite a challenge just to get composed and focused as the lightest areas are often an Exposure Value or only 3-4.

I could focus the lightest area, but with tilts and shifts, trying to make sure shadows are in focus etc it was a great challenge. In the end I got it as close as I could and stopped down. Which of course led to long exposures, made even longer by reciprocity.

We'll see how I did in time. If any of you have any low light focus techniques for 4x5 to share please do.
