Linear colour space (SG_CCFilter)

phile_forum · Post by **phile_forum** » Mon Jun 09, 2008 5:21 pm

Got a recurring problem with SG_CCFilter plugin. I know this isn't really the right place to ask but I thought I'd start here cos I know a few people are using this plugin.

Sometimes when I apply the input & output profiles to an image, the image goes completely black. Any idea why? Does anyone else see this?

Cheers,

Phil

Check You texture: when Your texture is dark - after SG_CCFilter received it very dark (but this is normaly).
When render and received too dark texture You can use brightnes under Image Editor (sometimes I make it, but maybe this is no phisical)
Maybe You have bad icc profiles?
I use only sRGB:

Thanks for the profiles. I'll give 'em a try.

I know what you mean about the images going darker when you apply the linear profile. I'm used to seeing that happen now, so that's not the problem. The thing is that sometimes they go flat black - every pixel to r,g,b 0,0,0 - when they quite definitely should not.

Restarting LW seems to help sometimes.

I guess it could also be something to do with running 32-bit LW9.3.1 on 64-bit Windows. Maybe.

Could You show any image?

I'm not sure that would help really - the problem is not consistent. The same image might be Ok one time but go black another time. It's more likely to be something wrong with my system I suspect. I take it you're not seeing this problem, JQ?

No
Sometimes when change brightnes or gamma in Image Editor - I receive bad image (in render I see horizontal lines on texture)

it's a bug in SG_CCFilter. Sebastian said he's trying to fix it but it's giving him some troubles.
