Working with the new computer

[janestarz]

Now that my PC has been upgraded, updated, and upthingummied, I'm trying it out on training wheels. NoKey took care to install the programs I need and that's lovely, because my day-to-day use of the PC is marginally affected.

He's also bought me a Bibble 5 Pro license, which is awesome. I'm still learning how to use it, but so far I'm loving it.

Using the program gave me a big scare today though. I opened up the pictures from last night's "Nieuwjaarsborrel" (drinkies for the new year) and saved a couple. Checked them in Gwenview and then the colours wer horribly green! Oh noes!
Well, let's check if there's any settings while I save, it could just be that.

I couldn't find anything at first so I did the smart thing and uploaded one to Flickr to see if it really was the photograph, or perhaps something else. The picture turned out just lovely on Flickr, so Bibble was showing me the correct colours. It couldn't be my monitor's settings, or everything would be as green as that. So guess what!? It's Gwenview! Making a mess of my lovely pictures, shame on it.



The left half is Bibble, the right half Gwenview. I just glued two screenshots together with the GIMP. Gwenview is messing up he colours! I'm not saying Bibble has got the right stuff, but Gwenview makes the picture look different than it actually is! I know that TL lighting is not my friend, but this is ridiculous!

Bad Gwenview. Now to fix it...this could get interesting!
To be honest, I never really liked Gwenview and preferred Kuickshow, but Gwenview is the default when clicking on a picture. Boo.

I think the default can be changed. It will take some doing though.

Was it really that red in there? The shirt on the Gwenview at least looks white, as I suppose it is, but on Bibble it looks pink. The hands do look a bit healthier on Bibble, but I don't find the colors of Gwenview weird.
However, if a thrid party (Flickr) tells you how it should look and you can choose which is the real one... I trust you. ;-)

It was quite a shock to see such a green image after the pinkish red thing I'd been editing in Bibble. I thought Bibble was broken!

Gheheh :)

Welcome to the world of color profiles and color management!

My guess would be that Bibble 5 is saving in Adobe RGB, which (theoretically) has a wider color range, instead of sRGB, which is the default for many. Flickr and other color profile aware applications handles Adobe RGB just fine. Gwenview apparently does not, the difference you show above is a typical result for left being shown naturally and right being shown in the wrong color space without any color conversion happening. That green cast is a typical telltale of an AdobeRGB profile being shown without conversions.

I'd suggest setting the working space of Bibble to sRGB for the moment until you find out what this all means. You can do this by either setting the working space profile to sRGB ( File->Preferences->Color Management) or by changing the output queue "JPEG Full Size" to include a conversion to that format. Pictures with the sRGB profile will still look good in programs that do not do color profiling, and this is what you've been using up to now.

I browsed by the colour settings of my camera earlier today, and I can choose between sRGB and AdobeRGB in there as well.

[aroka.livejournal.com]

Correct, keep that at sRGB. However, I believe Bibble 5 changes it to Adobe RGB by default when converting from RAW files, you want to change that for now. (I'm using sRGB too at the moment, least amount of hassle)

[janestarz.livejournal.com]

Actually, Bibble is set to sRGB. Now I wonder what's wrong with Gwenview....

[aroka.livejournal.com]

Try setting an explicit conversion to output color space to sRGB anyway (in the settings of the output queue JPEG Full Size, you can find it in the Output tab on the left, just to see if it helps. Oh and get a linux tool to check which color profile an image is in because I still believe there's nothing wrong with gwenview except that it's not rendering the AdobeRGB color profile correctly, (don't know a name by heart though, I'll try and lookup a tool later!)
