EOS R50 w/ 10-18mm Lens - Vignetting in RAW but not in JPG

germo11 — Fri, 13 Dec 2024 21:17:26 GMT

Having an issue with Vignetting when shooting on 10mm. Viewing it as a Raw file it has the Vignetting, viewing as a jpeg, no Vignetting. How do you view the Raw image and show the actual image without Vignetting?

Shooting on Canon R50 with the appropriate lens hood.

10-18mm lens (this only happens at 10mm)

Viewing on a Mac

Lens hood is sitting correctly on the lens as well.

Does NOT show the ring through the cameras viewfinder or screen.

I have been having to open all the photos in Lightroom and save them as JPEG from RAW to get rid of it, but this just takes so much longer and don’t even have the “raw” photo in the end.

Is there any way to just view it as a JPEG on Mac without changing the file? Once saved as a JPEG it’s fine though. OR is it just a setting on my Mac/camera that is messed up? Thanks in advance!

Do you have lens correction turned on. A lot of RF and RF-S lenses shoot a little wider than there stated focal lengths.

Peripheral illum corr is ON

Digital Lens Optimizer is set to Standard.

I tried changing all of these around as well with no luck.

Are you pulling up the RAW images in Lightroom. If so then you’ll need to apply lens corrections there. Canon’s DPP automatically applies as long as the lens correction profile is loaded on there.

Pulling the photos up in Preview just to cull through them, before I send them off to my editor. But I need to see the actual image to check composition etc. beforehand.

Lens correction isn’t being applied in the preview. That’s why you’re seeing the vignetting. Once lens corrections are applied it will go away. Also how bad is the vignetting post a sample picture in the forum. RAW images don’t apply lens corrections but JPEG images do by the camera.

Is there a way to apply lens correction in Preview? Here is one of the examples. It varies slightly.

I’m not sure if you can in Lightroom.

The camera applies lens corrections to remove the vignetting when it creates a JPG image. The same corrections are not applied to a RAW image. When you view the RAW image in Apple Preview it does not have the ability to apply lens corrections, so the RAW image will show the vignetting.

If you need to see the RAW image with the lens corrections applied on the computer, then you need to use a software that will do the lens corrections. Canon Digital Photo Professional is one free option, but Lightroom, Photoshop and several other applications will also do the same.

You could choose to set the camera to RAW + JPG mode so that it saves a RAW and a JPG image to the card each time you press the shutter. The JPG would have the lens corrections applied.
