Gimp is yet to achieve feature parity with Photoshop 5. not CS5 - just 5.
from 1999. And most pro users will not use anything missing features from
around CS2. 

Krita has most or all of them, by the way, and possibly some featues
photoshop doesn't even have, I'm not sure. If it's not a photoshop-killer
already it's certainly on its way. 

Gimp *could* re-brand itself as a simpler solution for amateurs, but for
that it would have to work on simplicity and even lose some features.

As a user, I believe this is a good idea. Certainly the "pencil" tool should
be eliminated and turned to a "anti-aliased" checkbox in the brush tool that
can be turned off. The airbrush... maybe call it "cumulative" - again, can be
just a setting. 
As for the ink tool... well - I think all of its functionality has been 
replicated by the current brush engine. It was useful when the brush engine
was primitive but it's very impressive now. Perhaps the ink tool can be
simply retired, pending community approval. 

Now, this is just my feelings, based on my own use patterns. I know I
basically only use the brush tool and very occasionally want to use the 
pencil tool. I NEVER use the airbrush or ink tools. So it would be best to
see what other users do with them before deciding.

I'm just a user but I would love to see this change so that the move tool 
could move a selection content. 
Another related issue though is moving a selection outside (partly or fully)
 the layer boundary. currently the selection content simply disappears. 
It would be nice if this somehow enlarged the boundary.

The problem is that there are two related dialogs, scale image and
print size. One only concerns pixel size, the other concerns print size.

It is true that sometimes you want to change both at the same time - for
example, when you edit pictures for print, you sometime want to scale them 
to a certain print size AND a certain resolution.

The best solution is unifying them to a single dialog, with Pixel size, 
print size and resolution controls. There should be a lock icon next to each
 and the three locks should work like a radio button, only one control can be
locked at any given time. So, you lock one, modify the second, and the third
changes accordingly.

Actually, there's no such problem. Google Play accepts GPL apps. Android 
itself is licensed under the Apache software license. Not only that but you
can also legally distribute apps without going through the app store - the
users have to change some default settings, but there's no need to jailbreak

That still leaves the problem of diverting valuable developer time into a

livensing and distribution are not the problem.

I'll be brief though:
What you think are UI issues are actually code issues. The boundaries and

You know, when you have a system that's probably 12 years old, it's good form
to start by saying that you have one instead of complaining that an application
developed in 2012 is "prohibitively slow". For example, you could use the

I knew what GEGL is, but I thought that was just the engine and that you'd put 
some sort of layer-based facade on it so people could, like, actually use it.
But it's your project, do what you feel right. Personally I hate node based
compositing, but perhaps you have a target audience for it, somewhere among
the 3d shader specialists.

It depends on what features this version will have. Gimp will have to go far
to attain the level of non-destructiveness Photoshop currently has. My bet
is, whatever feature you can think of in terms of non-destructiveness,
Photoshop already has it.

That reminds me - it would be great if the "save" feature also supported PSD
(As opposed to export). I can think of only one showstopper: text layers,
which are currently always converted to raster, and a further complication of
how to preserve the text data on a text layer that has been modified using 
another tool.

The reason is that some 3D and video editing programs support PSD natively
and even allow importing specific layers, so in some workflows, it is not
enough to just have a layered formats - it has to be PSD specifically.

Those are good reasons to do something, but I believe the problem is with the
selected solution and not with the idea of attempting to solve the problem. 
Photoshop Has a similar "protect user from destructive saving" system, 
annoying in its own way, which only lets you save to the original as long 
as no new layers have been added. Once you add layers, choosing "Save" opens 
a dialog letting you asve as PSD and you have to manually select JPG/PNG in
order to save. There is also a warning inside the dialog that data will be lost.

I can see that certain usage patterns will be easier using the new system but
perhaps allowances could be made in some cases. For example, if the image is 
kept
as a single layer, it should allow saving to all full-color, non-lossy formats.
If an image is saved to a lossy format, it could be decided that the first time
you attempt to do this, an alert will explain to you that repeated saving to JPG
corrupts the image. A checkbox in the dialog will enable you to prevent it
from showing again.

pixlr. It's a web app, not a standalone app. But it's pretty awesome.
It may not have ALL the features Gimp has, but it also has some it doesn't,
such as layer styles or some basic shape drawing options.
You can work with masks, layers, color corrections, all the things you'd expect.

Here's the problem - overwrite only works once. Then it becomes export.
And you can't assign the same keyboard shortcut to both.
You'll have to assign two shortcuts, and remember to use one shortcut the
first time, and the other shortcut the second, third etc.
That is indeed a strange behavior - a command that only works once per file.

Say what you will about save vs. export but this has to be fixed.

And what about making life easier for Linux users? There's a PPA that Ubuntu

It's also worth explicitly adding the "Mint" name there along with Ubuntu -

Another doomed effort to convince the team to rename Gimp.

This time there's a concrete suggestion for a new name ("Imagine")

[Gimp-developer] Retinex color operation

2012-04-25 Thread Michael Grosberg
I'd like to Discuss Retinex. I decided to do it here before submitting a
bug report.

In theory the retinex operation is very useful in fixing badly lit images.
In practice, I've had little success with it. So I decided to fiddle around
with it. My test picture was a Chinese temple on a background of blue sky
(I can upload the XCF on request). usually you want to just brighten up
some darker areas or bring detail in an area that's too brightly lit,
without changing the rest of the image. In my test case, The sky's color
was ruined when retinex was applied and most of the well-lit areas lost
most of their color.

I'll break down what happened:

1. The properties that can be changed by the sliders in the retinex dialog
are not clear at all. The documentation doesn't explain the first two in
terms understandable to a non-mathematician. Whatever it is they are doing,
they are not helping in correcting images. If it is opssible to give them
more descriptive names this would be great.

2. The result is too strong. I find I have to do a "fade" every time I use
it. My suggestion: add a multiplier slider that would do an internal fade.
The default should be about 0.5.

3. The algorithm is indiscriminate: it is used to fix bad lighting but it
also works on well-lit areas. I believe it should have less effect on
pixels (or areas) whose average luminosity value is closer to 0.5, and more
effect on pixels with values closer to 0 or 1.

I managed to achieve a selective retinex using the following method:
1. copy the layer
2. paste into quick mask
3. blur the mask using gaussian blur (8.0 radius)
4. invert the colors (only if you want to affect just the darker areas).
now your light areas are masked out.
5. use levels to also mask out the mid values: in the input scale, push the
black triangle to about midpoint. This part may require a different setting
for each image.
6. go back from quick mask to image and perform Retinex.
7. Fade the result

The above procedure can probably be turned into an integral part of retinex
so that retinex only works on those parts. Perhaps adding another slider
that emulates what I did with the levels operation, to choose how much you
want to affect midtones in the image.

Lastly a comparison to photoshop:
Photoshop's "shadow/highlight" operation (basically retinex) has two
sliders in its basic settings. One for choosing the strength of the effect
on lighter parts of the image, and one for choosing the strength of the
effect on darker parts of the image. So basically it's like doing what I
did with masks twice, one for dark areas and one for light, and combining
the result. There are also dual extended options, one set for dark areas
and one for light areas. In it there is a "tonal width" slider which
according to the help file does pretty much what I did with the levels
operation.
