Brightness and color adjustments?

Post by Reindeer »

To my surprise I find (or am not capable of finding) there is no way to adjust brightness or color adjustments of a layer in Moho. I was needing to simply lower the brightness of a background and find no direct or workaround way to do this. I find this bizarre, especially since the layer settings offer a bunch of more sophisticated options like pixellating, threshold, auto-shading, noise, different types of shadows, Toon settings and what not.

Moho is not made for that, such corrections usually would be done later in compositing/video editing.

But for some very basic corrections you can do this:
- put layer in group and activate masking
- create layer with black shape
- make your darkended layer the mask, set the black layer to multiply and some value of transparency.

True, but Moho does so many things – and it does them so well – that the lack of some basic brightness and colour adjustment (as can be done quite nicely in Animate) to my mind kind of stands out. Thanks for the workaround!

a variant on SlowTiger's suggestion that will also add some (VERY) rudimentary colour correction is, rather than black with varying transparency - any colour with varying tone will achieve this: pure white leaves the colours unchanged; pure black darkens everything to black; anywhere in between on the pure grey scale will darken, but if you have (e.g.) xff0000 that will leave all the red as red and all the other colours will be black e.g. magenta xff00ff multiplied by red gives red.

Continuing the variation, the mask need not be a uniform colour -- obviously depending on your actual moho file, you can make different areas of the mask (say) in the blue spectrum to accentuate blue in the sky and grey where there shadows.

Next, rather than masking, it could be possible to make a copy by ref of layers in your scene and then: set the copies to multiply; use colorize layer (animatable) to selectively reduce the brightness and make colour adjustments to the target layer. If, alternatively, the desire is to lighten, then use blend mode screen.

As a further variant, blend mode overlay (a combination of screen and multiply) can be used, but this changes the paradigm. The target layer is masked by the adjustment layer and is set to overlay; The adjustment layer is colorized -- mid-grey x808080 leaves colours unchanged; pure white makes everything white; pure black makes black; and all points in between.

Finally, it's worth remembering that you're not restricted to just one adjustment layer per "base" layer. e.g. you can have a "lighten with red tint", a "darken with blue tone" and a "no change" on the same base by using (animatable) masks to define areas of influence of the adjustments.

I usually make some color adjustment by just adding a new layer above all other layers then creating a dark or light colored shape covering the scene and a little margin outside the camera frame. Then I use the layer settings blend modes and adjust opacity of the layer in layer settings or the opacity of the shape itself with the fill color opacity. You can create fade out effect by applying heavy blur to the layer and moving the shape in the scene. You can also mask the effect to certain objects only in the scene. I also do some post color adjustment in a video editor. In the end it's definitly possible to get good colors with only moho.
