Odd Magenta in Shadows & Lens Data in Exif
« Reply #231 on: 19 / September / 2009, 01:21:26 »
Hi,

first of all: thanks to everyone involved to the CHDK Port for the 870is and the CHDK team in general. I was going mad about the lack of Detail especially in the shadows of the JPG's produced by the little camera. Raw support fixed this.

In the Wiki it said something about the colors being slightly off in DNG and i can confirm that. Basically it only affects Reds and Magenta to what i have seen and even the color tone itself seems ok. The thing is that the DNG image somehow treats the red shadow tones quite strange.

I put together a cropped part of an image that i took in China and if you look at the boys jacket on the right, even after combining jpg and dng into one image and exporting as jpg, its quite obvious what i mean. The jpg (left right side) is much closer to the "real" red tone... I dont know what to do about it and if it is a question of calibrating the raw import differently, but as all the other colors seem to be quite accurate, it seems as if something in the included LUT is a bit off...

Another question:
I saw that the JPG's include Lens Metadata, whereas the DNG doesnt have these. But also the JPG only includes the Lens in General (5-20mm) and not the actual focal length when zoomed in. Especially for auto correcting lens distortion, it would come quite handy to have this data in EXIF. Is it possible to access and save the actual focal length to the EXIF Data? Or, even more advanced, could the Auto Lens Correction Data (which the camera applies when saving the JPG's) somehow be added to EXIF Data - i know there is probably no program that could handle this but i guess from the amount of Lens Correction Software that exists, some friendly programmer could add code to handle this...

Cheers,
Till

Hello,

First, i would like to thank you for your work on this port.

In the CHDK manual i can see a "override aperture" entry in the "alt" menu:will this entry be available anytime soon or aperture setting is not possible with this camera?

Regards

no ixus/elph camera so far has been equipped with an iris diaphragm - they use a
neutral density filter instead, so all you have in 'extra photo operations' is 'ND filter state'
(Off = let Canon handle it, In/Out = force ND filter on/off)

Is there any reason to leave the beta tag on this port ? It seems it supports all the normal CHDK functionality ?
Don't forget what the H stands for.

I guess not really. If you need me to do anything to make this happen, just let me know.

B.t.w., I did just notice that the latest patch (remote synch fix, issue 289) hasn't been applied, likely because the actual patch wasn't uploaded. I've uploaded it now.
