Color-Correcting images inside Moho?

Post by DrNibbert »

Hello,

i want to re-use the same image-file multiple times but recolor it slightly for each instance. Is there a way to achieve this inside Moho? The idea is, that i don't have to create multiple image-files, but do the color-correction inside Moho and just work with one image file.
Is that possible somehow?
The only idea i came up with is using a instance of the image with a color-overlay (Colorize Layer) set the blending mode to Hue/Color?

Thanks for ideas?

I did this with black-and-white images and an overlay set to multiply, both in a group, the image serving as mask for the colour layer.

Other than that Moho doesn't offer any colour changing operations on bitmaps.

what I've often done is to make a greyscale image with highlights around xD0D0D0 and shadows around x303030 (and neutral at x808080), then have a colour layer with blend mode overlay over that. You can use the greyscale as a clipping mask as slowtiger says. Combine more than one set of colour-overlay/greyscale clipping mask groups to get what you want. Animate the colour fill if you wish. Most of the textured / animated colours in this are done that way: https://www.youtube.com/watch?v=iN-tXtQi-Yg e.g. the opening title; the terrain; the star showers...

so, to answer your question - assuming you want an Andy Warhol effect -- what I'd try is:
> greyscale the image;
> create "region" masks either by "element" (e.g. hair, eyes, nose ..) and/or by (e.g.) posterizing (to separate out shadows, highlights etc) to create a complementary breakdown of the whole;
> have a set of colour overlays that cover the whole image - typically single colour for Warhol but there's no real restriction;

Colour Set 1
>Region Group 1 - masking hide all
>> colour 1 - blend mode overlay - mask this layer
>> greyscale image - mask this layer
>> region 1 mask - add to invisibly to mask

> Region Groups 2 onwards - same construction for each separate region...

Colour Set 2 -- same again but change the fill colour layers.

A little thought will allow extensive use of "copy by reference"

Hope that's useful .. if not please say.

Thanks a lot for those great ideas! :-)

This Greyscale + Color-Layer technique is exactly what i was looking for, perfect :-)

But how is it possible to use an image-file (with alpha) as clipping mask for a vector-layer? I tried the same way as i would with 2 Vector-Layers (both in a group, group set to 'Hide all', the image set to 'add to mask', the vector to 'mask this layer') but i just see a rectangular mask instead of the outline of the Alpha?

Edit: Aah, i just realised that this is once again the "GPU Acceleration ON/OFF"-Problem, when i turn off GPU it is displayed correctly :-)

glad to help! (and yeah - I almost always keep GPU off too!)
