If you want to reset the preferences of a project press and hold shift + alt while the program starts.
As far as I know this is true for both AFX and Premiere.…

Extending the framing of a render

Johan Borgström — Thu, 03 May 2012 12:33:13 +0000

In a recent project I needed to “extend” a render from 1280 px to 1920 px without changing the perspective or camera position of the composition. What I wanted was an image that was larger and that would “extend the content” outside the smaller one. My first idea was to use the pan and zoom attribute of the camera, but this wouldn´t render with V-Ray. So I needed to come up with something else. I started to look at the focal length of the camera. There should be a relation between the focal length and the image size, right ? 1920 is 1.5 times bigger then 1280 (1920 / 1280) and the inverse is 2/3 or 1280/1920 (0,666666667) as a sidenote to get and inverse of a value simply divide 1 with the value you wish to invert (1/n). So to get the correct focal length we divide the focal length of the camera used to render the smaller (1280) image with 1.5 and we get a focal length of 23,33333333. We set the focal length of the camera used to render the larger (1920) image and voila we have a match. Below you can see a test render I did to prove that I got what I wanted. The image in the center square is the smaller render on top of the large one. Nice !

Print Pretty with Python

Johan Borgström — Fri, 20 Apr 2012 10:53:22 +0000

To print your stuff in a more human readable way you could use the pprint module. Simply do the following:


import pprint

pprint.pprint('your nested dict or whatever')

V-Ray render shadow pass

Johan Borgström — Mon, 16 Apr 2012 12:47:56 +0000

This is a setup to render a shadow pass using V-Ray.

Assign a regular V-Ray material to the ground plane.
Add a single object properties node to the plane.
In the vray object properties node under the Matte Properties rollout enable the Matte surface checkbox, set the Alpha contribution to -1, enable the shadow and Affect Alpha checkbox.
Add a single object properties node to the shadowcasting object(s).
In the Visability options disable everything but the Cast Shadows checkbox. You could also turn off the Additional surface properties.

If you are using a maya native directional light make sure to turn on use ray trace shadows.

Afx Tip: Transform Multiple Selection

Johan Borgström — Mon, 16 Apr 2012 09:35:00 +0000

Change position, rotation, transparency of multiple selected layers. Select the layers you whish to transform press Ctrl + Shift + P for position ( use other keyboard shortcuts for the other properties ). Nice !…

Photoshop tip: Virtual slider

Johan Borgström — Sun, 15 Apr 2012 14:07:31 +0000

When using sliders in PS a nice tip is to use the virtual slider. To do this click n drag on the text. To adjust the exposure click on the text “Exposure” and drag left/right. Shift, ctrl and alt are “sensitivity” modifiers. Double click to reset to default.
