Color Menu Analysis

Auto

These aren't professionally tools for photographers. None of them has a dialog box with parameters giving control over the effect. However the results are often very good for enhancing small images used for creative art and web design.

Components

Channel Mixer

• it should stay in core GIMP with enhancements, it works particularly well when converting to monochrome
• values should be in percent
• changing output channels should have better UI solution
• 'save' option should be developed to enable easy access to different pre-sets ('personal filters'). User should not worry about the files. GIMP should store it in the right place and add pre-sets to a popup menu. User could manage pre-sets (delete etc.) via this popup menu. Other tools could work in a similar way.

Compose

• could be combined with Recompose
• better solution for unavailable options could be implemented

Decompose

Should stay in core GIMP. Simple and quick

Recompose

• could be combined with Compose
• problem: if original image is closed, it doesn't work

Map

Adjust Foreground and Background

It should be removed form the core GIMP. It does not work as expected at the moment. Other tools can achieve similar effect in a better way.

Alien Map

it should be possible to: - reset values - save parameters - experiment easily with better sliders (better default setting, maningful names, better behaviour of parameters), no check-boxes (modes should be changed in different way)

Color Exchange

- default threshold setting should be above zero, so that the changes at visible - improvement of color selecting (etc.)

Color Range Mapping

The hue direction (cw, ccw) of how the color changes from the first range to the second should be presented, to have better control over the effect.

Gradient Map

nice and quick

Palette Map

nice and quick, might become even more powerful when implementing 'blobs of paint' concept

Info

Histogram

It should be combined with other filters. It seems not to work as a stand alone dialog. After setting levels further judgement is more artistic (done by eyes), rather than technological wise.

Border Average

This should be done in a better way. Implementing color picker, that would enable to get an average color from selected area, will be a better solution, than choosing only border average.

Colorcube Analysis

Part of the functionality of this tool should be implemented in other dialog (like saving file), when given information is really important.

Draw HSV Graph

crushes, no description on docs.gimp.org

Smooth Palette

Creating a palette from the image colors should be done within palettes. This dialog should disappear and become a kind of palette feature. However then better parameters should be implemented.

Other

Color to Alpha

User control over this filter should be improved. Color picker should be as powerful as the one in the toolbox. see [effect]

Colorify

It should have a good color picker instead of few old-fashioned colors. Doesn’t seem to meet the goals of artists. see [effect]

Filter Pack

• Not relevant, other tools support its goals better.
• No-concept and not coherent UI.
• Should probable stay out of core GIMP.

Hot

"It identifies and modifies pixels which might cause problem when displayed onto PAL or NTSC TV screen."

• is it being used?

Maximum RGB

direct enough see [effect]

Retinex

• Should stay in core GIMP - good for original intent and experiments.
• Needs goal oriented UI.
• Better parameters needed, not too technical and with more meaningful names.
• There should be possibility to save the parameters.
