I scratched my focusing screen – Square crop on Canon 5D II

personal tips & tricks, photo gear

Since photographing with the Rolleiflex camera, I have enjoyed it so much that I wanted a square crop compositing aid on my Canon 5D mark II.

I had read about Katzeye optics on the internet, mailed them, but they were unable to make me a replacement focusing screen for the 5D II.

After searching the internet, an alternative option seemed to be unavailable.

I have been using a special focusing screen replacement for a while (Eg-S, also called super precision focusing screen), that has a better visual reference for the actual depth of field.

This has left me with two no longer used focusing screens (the original ones for my two camera’s), so I thought I’d give it a go.

Brute force and an ‘I don’t care’ mind is the only thing left 😀  so I decided to ‘scratch’ my focusing screen with square crop lines.

What you’ll need:

A focusing screen that is of no importance to you (one you can do absolutely without)

A needle

An iron ruler

A loupe

A fine marker pen

fine motor skills

some nerve.

Some pictures of the process (I’m not responsible for any camera abuse that might result from this blog post)

focusing screen square crop

the following steps will be needed :  (FS=Focusing screen)

1. With the help of the focusing screen replacement tool (delivered with the Canon focusing screen replacements) you will remove the FS.

2. With a fine marker put a small reference dot at 6mm from the edge of the ground surface of the FS, this is not the edge of the FS.

3. With a metal ruler and a sharp needle (any kind of sewing needle will do) just slightly scratch the ground surface of the FS parallel to the edge of the FS.

4. Do this on two sides (left and right)

5. Put back the FS in the camera, with the help of the provided tool.

Tadaaaah, two vertical lines in the ocular view. They give at least an idea of where the square crop will fall.

architectural compositions

architecture, Personal Pictures

When I was still in my architecture module (evening classes photography) we were asked to photograph a museum interior with composition in mind. Not the building as such was important in the result, but mainly the distribution of elements in the picture. Not a simple, but a very interesting exercise. Balancing weights, colors, working with lines, structures, perspectives. Photography becomes a very graphical art. The building is a museum building in Ghent, Belgium.

It is absolutely necessary to work on tripod for such an assignment, because this allows you to carefully study your preliminary results, and eventually do very subtle corrections to your composition. I have a tripod with a 3-way head, which is interesting, because you can just modify one axis, without moving the other ones. (vs. a ballhead, which releases all axes at once)

I just noticed yesterday that I hadn’t published these images before, so here they come. Clickable for a bigger size.
