[Gimp-user] Howto composite over- and under-exposed images

2005-11-20 Thread Milan Knizek
Hello,

is there an easy way to to take shadows from over-exposed image and highlights 
of under-exposed image and composite them together? (Assuming the two images 
are exactly the same, e.g. take from tripod or in a quick bracketing 
sequence.)

I know I could use manual masking of affected areas of one image, however, I 
would prefer to have GIMP create a mask for 'highlights' automatically (with 
soft transition to shadows) or even manually on a basis of a transition 
curve.

Thanks,
Milan

 You can do it with layer masks:

 ..or you can use an automated tool to build up a high dynamic
 range composite:

 Cinepaint 0.20 has a plugin that does a similar thing.

Thanks for the extensive answer, I have been using cinepaint but was not aware 
about the new plugin.

[Gimp-user] Transform selection, lock layers

2005-11-20 Thread Remus Boara

Hi everybody,

I would be a very happy GIMP user only if you could let me know how can 
be transformed an image selection or other object's selection.


Also, some quick questions: cannot find anywhere info about how a GIMP 
layer can be locked or if the layers can be organized into directories 
or some other way?


Thanks a lot.

thanks a lot for the answer, very appreciated.
regarding the selection transforming was actually referring on how to 
edit / modify / adjust a selection?

what would you like to transform the selection into? There are  
possibilities to transform them into masks and paths in GIMP??

As far as I know there is no way to organize layers in a tree  
structure neither can you lock them in GIMP right now.


But may be I'm wrong?

Thanks a lot.

Once a selection is made it is treated internally as raster data - 
that means it is impossible to, say, increase an elliptical selection 
radius after it is ready (but people are working out a way tot hat 
with rectangular selections).

But all transform tools (move, scale, rotate, perspective, etc...) 
have mmodes to operate on the selection.  Just select one of the 
transform tools, and on the tool options dialog, pick the work on 
selection (second icon on the top of the dialog).

With most tools, the work on selection mode can also be achieved by 
holding ALT while clicking -  but ALT + click is normally used by 
Window Managers, so the combination often  doesn't work.

[Gimp-user] GIMP single instance

2005-11-20 Thread Remus Boara

Hi,

How can I have only a single GIMP instance?
If I have GIMP already open and I double click on some xcf file or other 
this is opening me up a new GIMP instance. I would like to have opened a 
new window on the same session.


Thanks.

 thanks a lot... i downloaded the manual it should be fine.
 I'm really sorry for my persistence but just found another thing
 that worries me:

 if i have a group of graphics, how can i move them across the
 canvas all together? i'm talking about lots of layers that needs to
 be located on some other place on the same window without merging
 them into a single one.


Although there are no layer groups or trees in the GIMP, you can have 
a single layer group, formed by linked layers. To link a layer, you 
just click on the layer dialog next to the visibility ?(eye) icon - a 
chain link will appear to indicate it is linked. Whenever you perform 
a transform - move, scale, etc..., it is performed in all linked 
layers. 

To move another group of layers, you have to unlink all the previous, 
and link all layers of the set you want to move.

[Gimp-user] file types

2005-11-20 Thread Cliff Hanley
Since I installed Gimp, all my image files on desktop are IDed as Gimp files instead of JPG, BMP,TIFF etc. It would be useful to see these IDs before clicking on the files. Is there an option forrestoring them?

Install the program that created these identifications, or restore
your mime-types from a backup.  (You do have a backup, don't you? ;)

Maybe also installing another program might overwrite GIMPs type
settings with it's own, which are then used thereafter -- if the
program restores the JPG/BMP/TIFF/etc types, then you should be fine.

It depends on the type of desktop - IIRC, different ones (GNOME, XFCE,
MS Windows) use different ways of identifying file types and showing
them to you.
