We had a nice discussion in the forum about how to crop. What shall determine the crop, the output paper format or the content of the image?
The two main aspect ratios used in digital cameras are 2:3 and 3:4. This has technical reasons – not artistic considerations. Then there is a flood of different formats for papers, from ancient to the modern A-series. The big question: How do you fit your camera image onto the paper?
I show two ways of getting it right. One is to leave a strip of paper white and cut it off later. Or you put the image into the centre of the paper and leave a nice white border around it. For both a bit of math is needed.
In the video I mention a script for getting images straight – a rotation tool on steroids. You find it at Ray Adagio’s Script Manufacture.
What happens in the camera when you change the ISO? This is my topic for the tech part of the show.

You did mention a script to rotate the image… I would like to know which one you’re talking about, thank you in advance!
… and: Nice show, as always!
I have added the link to Bert’s script in the show notes above.
You are using quite a nice virtual gimp blackboard, I could recreate that easily by creating a grid (Filter->Render->Pattern->Grid), and I also tried to mimic your chalk.
The trick seems to be in the ‘jitter’, setting of the paintbrush or pencil.
I actually used a paintbrush, so that the pressure on my wacom influences the hardness and size.
Maybe you can explain your settings for chalk to us, your fans
The chalk is the smallest of these animated pencil sketch brushes, scaled down a bit and with a bit of jitter. I’ll show it next time.

the scripts are not down-loadable!
anyone knows where to get them from another site maybe? thanks
Click the script button with right mouse button and save target. This should work.
@Bert: You have a user interface problem there?
@ Rolf: Das kann man wohl mit Fug und Recht behaupten!
Translation: Yes!

Perhaps, this is worth reading:

A lot of people do crop using Rule of Thirds. New insights, worth to investigate.
I’ve read an article in a dutch magazine Zoom.

Another excellent show. I miss the tech talk, but this episode helped me a lot to understand ISO.
I still have trouble deciding what ISO to shoot at but now I have a better idea of what it all means.
Very creative use of the Blend tool. This totally explained ISO Noise to me in a visual way.
