I just downloaded and built rawstudio 1.1 on my Fedora 8 box.  Kudos to
the team for bringing it to life.

I've been using ufraw for ages in combination with gqview.  Its a
painful way to work with raw images because the viewing and manipulating
of the images isn't coordinated.  I've been looking for something better
for a long time.  

I love the way rawstudio mimics Adobe Lightroom.  I've considered buying
Lightroom several times, but it doesn't run on Linux.  And of course it
isn't open source.  But I have always liked the layout and workflow of
it.  Its nice to see that rawstudio incorporated its basic concepts.

Unfortunately, rawstudio doesn't work particularly well for me.   I'm
not sure if I am missing how its supposed to work or if it needs a bit
more development.  Nevertheless, here are my issues:

#1) When an image is selected and placed in the main editing window, it
needs a lot of adjustment to get near the final product.   

In ufraw one can select between using the camera settings for the
parameters or one can save a set of parameters and they get applied to
every image that is worked on.  I don't see how to do that with
rawstudio and thus the images require a lot of adjustment to get to the
final product.

Its interesting that the small images in the library view bar have
pretty good image parameters and are much closer to the final product
and thus would be a good starting point for displaying the image in the
main editing window.

#2) The image adjuster sliders are quite coarse and finicky at least on
my computer with my 40D images.  For example, the tint slider moves from
-2.0 to 2.0.  I question if such a wide range is really needed.   I
don't need anything nearly that wide.

The wide range of adjustment leads to finicky operation of the
sliders.  

A single mouse wheel click on my system is 0.20, which is pretty coarse.
To get finer adjustment than that, I have to use the mouse pointer to
adjust the slider and that is a pretty finicky operation, especially
when it needs to be done for just about every image parameter.  

Between 1) and 2), it just takes too long to get every image adjusted to
the final settings it needs.

I wonder if the parameter numbers on the left of the sliders could be
made into text edit boxes with up/down arrows for fine tuning.  ufraw
does this and it seems to work pretty well.

#3) I need a white balance spot selector.  Ufraw has a good whitebalance
spot selector whereby one can select a spot as gray and then use it to
adjust the white balance for the rest of the image.  I often shoot gray
cards and use them to calibrate the white balance on my images.  I find
that this single adjustment can make the most incredible difference on
an otherwise correctly adjusted image.

I look forward to feedback on my issues.   Please don't take my comments
as negative criticism of rawstudio.  I am very happy and excited to see
what a great application rawstudio will be with just a few tweaks. 

In any event, keep up the good work.  I am available for testing should
the team want my further input during the develop process.

LG
