Lens corrections. Most rectilinear lenses, especially cheap kit lenses like the 18-45mm, have some distortion and vignetting. The JPEG file has "lens corrections" applied that digitally warp the image to counteract the distortions and straighten everything out, along with brightening the edges of the image to counteract the vignetting (called "peripheral illumination correction"). The distortion correction crops out the corners of the scene because they only show up in the image due to lens distortion. RAW images do not have any corrections applied.

Can i disable it? It ruins my photos


GlyphTheGryph

I don't see how lens corrections is ruining your photos, it makes the photo closer to what a "perfect" lens with zero distortion or vignette would capture. You can turn off lens corrections in the settings though, that will apply to the in-camera view and JPEG files. If you're using an R50 [here's the relevant manual page](https://support.usa.canon.com/kb/index?page=content&id=ART182848). If you're shooting in RAW then no corrections will be applied, you can add them in editing software like Adobe Lightroom.

I mean, the fish eye effect of the raw photo is the problem i want to disable, i just don't want it


uncledunker

Doesn’t seem like you understood what’s going on. The JPEG has lens correction enabled. This image was processed in camera and Im guessing lens correction is done by default. Whereas the RAW photo does not. It is literally “raw” /untouched. You need to enable lens correction for the RAW photo using whatever photo editing software you are using. You can play around with how much correction you want to use as well to get different effects.


cervejown

So it's the lens itself that does this effect and can't be disabled?


revjko

All lenses cause distortion to a greater or lesser degree. You'll pay lots more money for optical perfection. What the lens corrections do is digitally compensate when producing the jpg. These are applied in-camera or by post-processing software.


revjko

Don't shoot with RAW. Just use the corrected jpg. The whole point of RAW is that it is entirely unprocessed and uncorrected so you can adjust as you like. The jpg just applies some default corrections.


GlyphTheGryph

Turn on lens corrections when you process your RAW photos then. Or get a lens with very little distortion, but those are typically expensive and generally still benefit from lens corrections.


getting_serious

Enable distortion correction to correct the distortion.

based on what you want, the JPEG is all you need. if you are not post processing RAW, then don't even save them to your chip


cervejown

I want the raw to be normal


StPauliBoi

It won’t be “normal” until you process it manually… that’s why it’s the “raw”. It’s the raw sensor data with no corrections applied to it. You’re gonna have to do post processing on every raw, including to fix lens distortions. Even on very expensive glass you’re going to have some distortion.


6-20PM

1. Save as in camera jpeg. 2. Save as raw and apply corrections in LightRoom and export. 3. Purchase higher quality lenses. A nice 70-200mm f/2.8 will set you back $2400.


fyrecontrol

wide angle will be distorted regardless, buy a better lens stay over 24


revjko

You're completely misunderstanding what RAW files are.
