Canon SX500IS Camera and lens profiles

The Canon Powershot SX500 IS camera does not seem to be supported in Rawtherapee.
I am currently using the settings for the SX510HS model.
I suspect that it is not 100% compatible and probably needs manual tweaking to produce the correct image alignment.
I have the latest CHDK firmware installed on the camera memory module.

I’m a newbie with this software so any advice would be most welcome.

Thanks,

John.

Which “settings” are you referng to? Which version of RawTherapee are you using?

Thanks for the prompt reply!
I have latest Rawtherapee version. ( 5.3 )
The settings I’m referring to are the Profiled lens corrections in the Crop section of the tools. ( Camera, Lens )

@johnnymcg you probably need to follow this:
http://lensfun.sourceforge.net/calibration/
First check whether your lens isn’t already supported by the latest development version of lensfun.

Thanks for the suggestion Morgan.
Unfortunately the Canon Powershot SX500IS is not in the Lensfun latest version either.
The Powershot SX510HS is there though.

That page has instructions on how to proceed.

Thanks, Morgan.
I sent off a request for support of the Canon Powershot SX500IS camera/lens.

@johnnymcg If you don’t sent the pictures it’s almost unuseful…

Here you can find instructions for distorsion calibration that i think is the most important part:

http://wilson.bronger.org/calibration

Once you’ve got the raw images, you can upload them there.

For ca with that camera you can use autocorrection, for vignetting you need a white plexiglass that doesn’t exceed 3mm thickness, and a a lamp. You surely can find how to proceed on lensfun page, it’s really really ultraeasy.

Thanks for the helpful instructions. I’ll see what I can do regarding getting the images uploaded.
