Raw Samples Wanted


(ಚಿರಾಗ್ ನಟರಾಜ್) #44

Yeah, that agrees with what the manual says. Also, certain camera makers (cough Panasonic, Sony) actually crop the RAW file?! Like, Canon does it for the JPEGs (makes sense), but they don’t touch the RAW (just verified this by shooting a photo in 1:1). Good on Canon for being sane about this.

Don’t know about sony, but they do even worse thing - apply lens corrections (vignetting, maybe CA) to the raw.

Hmmm. Just shot an image and pressed Info while looking at it. I think Canon does this as well (by default, anyway) - I just took a look at my camera settings. I don’t know if they apply it only to JPEG or if they apply it to RAW as well (the manual isn’t clear). Okay, looks like they’re doing it to the JPEG but not to the RAW. Cool, they’re sane about this as well.


FYI, https://raw.pixls.us is currently inaccessible, at least from the guest hospital WIFI network…

Works here. You can use http://downforeveryoneorjustme.com/ to check if it is just you or down for everyone.

Works for me.


Carry on then. I forgot to check as @Tobias mentioned. Makes me unable to verify SL2 support for the other thread.


Want to upload the new A7iii files but the raw.pixls.us is not reachable via https. I can ping it though.

Thank you for your (future) contribution! We’ve opened an issue with our sysadmin to rectify the problem. Thanks for reporting! Please try again later. :smiley:

Sorry about that, was traveling a bit. It should al be in working order again.

Ok, great.

But I do have a few questions.
I own some cameras, therefore one to help the the software I like so much.
What kinda of pictures are yall looking for? Is there any ISO, Lens or anything like that to be used?

(Tobias) #55

Have a look at https://raw.pixls.us/ :

We are looking for shots that are:

* Lens mounted on the camera, cap off
* Image in focus and properly exposed
* Landscape orientation

We are NOT looking for:

* Series of images with different ISO, aperture, shutter, wb, lighting, or different lenses
* DNG files created with Adobe DNG Converter
* Photographs of people, for legal reasons.

It would be easier to discuss this on case-by-case basis.
(i.e which cameras?)

I think i have explained that in the first post.
Just some normal landscape-type image - low iso, normal exposure, no people in the frame.
If there are multiple samples, they should have the same content - taken via tripod.

I have an EOS 80D, an EOS 5D Mark 4 and a Powershot G7X Mark 2. I do not have a color target. I’m still not clear on what sort of files will help you. If there’s something I can help with with my gear, let me know.

(Mica) #58

Does the G7X shoot raw files? There are already samples for the other two camera you have.


Yes it does. See: https://www.usa.canon.com/internet/portal/us/home/products/details/cameras/point-and-shoot/advanced-cameras/powershot-g7-x-mark-ii.

(Roman Lebedev) #60

Thank you, but we already have the full sample sets for all these cameras. So no new samples are needed.

(Stampede) #61

Alright. I saw 4 samples listed for the G7X, but only one listed for G7X Mark 2, so I thought you may be missing some from the Mark 2.

Any specification?

Yes, read https://raw.pixls.us, all the information is there, or further up in this thread:
