Assignment 5: Texture Library
Assigned: November 16th
Due: November 27th by ftp
% of Final Grade: 10%
File sizes should be under 2 mbs, around 2048 px max.

Build a sample texture library
Aim for a variety of surfaces, colours, and textures.
Minimum number of images: 12
Include at least 4 examples each of walls, ground, and details.
Try to find images you can use in your project -- ie you need old, grungy textures.
You may reuse images you shot for your 'entropy' project.
Shoot in flat light, dry weather, perpendicular to your subject.
Correct the white balance if you can.
Make sure they're in focus.
Shoot a large enough surface area if it's potentially tileable, and get close enough to the subject if it's a detail.
Avoid perspective and warping by zooming in from a few steps back.
Edit in PS -- crop out extraneous details, use levels, contrast, and hue & saturation to bump up details and get rid of fake-looking colour casts.
Remind yourself of keys to good textures on this site:
