Thanks. 😀

Can you please clarify the price that we pay by increasing the JPEG size to match the sensor size?

Maybe the colour values in the extreme edge pixels may be incorrect, but at least you get more FOV. Are you saying that making this change degrades the quality of the remaining more-central pixels?

I did search the forum, but only this post came up when searching "Active Area".

Thanks
Elia

bether, it is not good idea. Increasing active area, you get thin black borders around the image (these borders are blind areas of camera sensors). Increasing Jpeg size (or crop size) you get interpolation artifacts during developing DNG file. Properly crop size serves to avoid interpolation artifacts

heya artden, a few feature suggestions to get you going once you're back from vacation:

1. please catch the "folder not found" message, when at startup your program tries to open last used folder (and this folder was renamed or removed). i get it all the time, because i delete my raw folders after i processed everything to dng. windows plays that damn annoying sound once it detects your error message.

2. add an option to not develop RAW files that dont have corresponding jpg file in folder (perhaps with a checkbox in the mainscreen). i thought i can have a workaround for this by selecting just the raws that i wanted to be converted, but it still converts ALL raws it can find, even those without corresponding jpgs. so perhaps adding this checkbox i mentioned and also the option to "mark" files in the list, so that only these get converted?

3. there is a bug involving *.wav files (RAW files that got the extension WAV from the raw merge/sum feature in chdk). while your program parses the folder fine and shows the wav files and the corresponding jpg, it does NOT convert it if there is a raw file with the same number (but the crw extension). workaround: rename the file to another number, but then there is no corresponding jpg file. you know what i mean?

thanks for working on this fine piece of software!

thanks in advance, PhoX

Hello,

is there any trick only convert the marked pairs of CRWs/JPGs?

Or is this a feature of comming betas?

thanks

perhaps you should have searched the forum/thread for this specific request.

oh wait a minute, maybe you only should have read the post directly above yours 😉
i requested the same thing (maybe i added a little text to it 😁) 😁

Ist easy to search, but difficult to find 😁

"marked" and "selected" didn't show any result 😉

OK - so this will be a comming feature.

Pictures for ixus40 :ixus40_shot.tar.gz

Those values were more or less guessed...

 { // Canon Digital IXUS 40
                        L"Canon DIGITAL IXUS 40", // name checked
                        2400,1720, 12,24,6,12, 2272,1704, 31, 1023, MOSAIC_TYPE1, // ??
                        lsDaylight, {0.652674f,-0.172074f,-0.107575f, -0.139063f,0.594517f,0.060252f, -0.009088f,0.082013f,0.23808f}, //??
                        {1.0f, 1.0f, 1.0f},

                }

For dcraw this opens ixus 40 raws:

Thanks for your work on this, ArtDen!

Here's an image for the SD 450 / IXUS 55: http://www.zshare.net/download/17290644c8fe67e6/

Files with test images for color profile calculation for PowerShot SD 950IS / IXUS 960IS:

Raw: crw_0333.cr2 - 14.91MB
Jpeg: img_0333.jpg - 3.25MB

Reply if you want me to take other shots to make a color profile for this camera model.

Thanks 😀

Alrighty, hopefully this works (CHDK is currently being ported to this cam). It's from the IXUS 80IS/SD1100IS:

zSHARE - 80is_sampleraw.zip

Archive contains JPG/CR2 file.

ArtDen

I'm little busy right now and will process your files later.

Here is another IXUS 80IS/SD1100IS JPG and CRW:

Ok, so after messing around for a couple hours, I finally got a good calculation of my IXUS 80IS/SD1100IS

The matrix is:
0.959050 -0.288102 -0.157138 -0.126103 0.801766 0.014220 -0.019093 0.101675 0.258339

Here is a picture that I took, and tweaked some settings, but left the white balance settings to "As Shot". I also shrank it and made it a jpg. It is the light rail in Charlotte, NC. Incase anybody wondered.

When I did the conversions before, by using the S5 camera setting or something, I could really have to mess with the white balance setting in order to get close to this, because the Darker grays would be purplish or something.

Excellent!

Would also love to see support of IXUS 960IS / SD 950IS.
Tell me if I can assist with more test images than the ones I provided in Reply #293 of this thread.
