Hi all,<br>
<br>
today I spent some time with digikam's new raw importer in 0.9.5svn and can<br>
confirm once again that it has improved a lot over the previous versions.<br>
Nontheless, I would like to ask some unrelated questions about it.<br>
<br>
<br>
1) white balance.<br>
Do the settings "default D65", "camera", "automatic" just correspond to fixing<br>
some value of the temperature? </blockquote><div><br>Use SHIFT F1 over the settings to have explainations.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Or are there some more internal settings<br>
involved? If it's only the temperature (and green tint, maybe), it would be<br>
helpful if the chosen temperature would be indicated on the slider, with<br>
dragging the slider changing whitebalance to manual mode.</blockquote><div><br>i like the idea.<br></div><div> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
2) black and white.<br>
I don't understand these settings very well, but that's probably due to my<br>
limited photography knowledge ;-) My guess is that with these sliders, you can<br>
cut off the spectrum at the left or right hand side. Is that correct? </blockquote><div><br>yes. it's the black point and white point.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
If yes,<br>
it would be great if this cut off could be visualized in the spectrum depicted<br>
in the importer. Or how can I see what value is appropriate?</blockquote><div><br>this is that i would to do but with dcraw it's impossible. The histogram to cut is an internal one used during the demosaiced process.<br>
<br>i will trying to see if libraw will be better for that<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br>
<br>
3) luminosity curve.<br>
For consistency with the rest of digikam, maybe for "reset to linear" the same<br>
button as for all the other reset buttons could be used. The micro button<br>
which is used right now can actually easily be overlooked.</blockquote><div><br>planed.<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
<br>
4) workflow for imported images.<br>
After the raw image is imported, usually some more adjustments like crop,<br>
sharpen, etc are made. What is the intended workflow here?<br>
I started out with importing the raw image, save it to something non-raw, and<br>
then do further adjustments. Or can the tools in the image editor work<br>
directly on the raw data? </blockquote><div><br>no. editor use a demosaiced image converted to RGB color space. <br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Well, when I save the imported X.raw to, say, X.jpg<br>
and then do some more changes, I have the problem that saving after these<br>
changes does not work - digikam refuses to overwrite X.jpg with the changed<br>
X.jpg, and I am forced to pick a new file name. So I usually import, save to<br>
jpg, close the image editor, open the jpg again and then do the other<br>
adjustments.</blockquote><div><br>I don't recommend to use JPG in your workflow. Use PNG instead.<br><br>your problem to overwrite an existing image is new for me. Somebody can reproduce it ?</div></div><br>best<br><br>
