Noise photos?

Deforges

A lot of tuts for texturing have been giving the helpful advice to use natural noise as opposed to photoshop filter generated. I've googled and searched to my wits end and I can't find any photos or anything. Does anyone have something to help me out?

Got a scanner? Scan anything with a flat plastic surface such as a lunchbox. You get a great image (especially with high DPI scanners) with loads of believable scratch detail. And if you don't wipe it down first fingerprints (maybe/maybe not useful?)

Snader

Go to something like CGtextures and grab some images of various materials that feel similar to the surface you're working on. For example, this is a simple flat red overlayed with a texture from CGtextures and with photoshop noise. Because of the specific plaster-texture in the source image, it immediately feels like a wall, and not a filtered undefinable object.



So what you wanna look for is "[nameofwhatyou'reworkingon] textures" and not "natural noise texture".

I use nukex noise profiles for "film noise", but if you need some raw random noise, here is a folder with some noise samples in .exr that might help you:

Those definitely helped! They're great. Thank you very much

Also google image for sand textures. They convert to greyscale 'natural' noise quite well.

A neat trick I use for noise is to grab a metal, concrete, or wall texture and use the Photoshop high pass filter to remove most of the major variances and to zero it in closer to %50 brightness. Then you can overlay this on top of your textures and work with it from there.


I think Racer covered this in a tutorial of his. Most noise from Photoshop looks unnatural because it has no structure, and our eyes look for it. So if you can use something that has a bit of structure (even if it doesn't match the material you're trying to achieve or is unrealistic) then you should have something at least close to believable.
