Affinity Photo - Raw image lens auto correction

Recommended Posts

Hey guys,

I have been shooting photo with Sony A6500 with two lens which is supported with SerifLabs RAW engine. I am using Affinity photo 1.6.7 on my Mac.

When I open the raw file within Affinity photo, it appears the application did not perform auto lens correction, but the application can read camera and lens info correctly. As you can see from the images below:

Very new to this forum, if I missed about a solution which provided by others before (I searched for it but couldn't find any), please guide me to the right direction :)

 

Cheers,

Alex

Hi Gabe,

Thanks for the reply and the beta version, I have tried it with photo taken from Sony A6500 with Sony 18-135mm f/3.5-5.6 lens, unfortunately it doesn't work as expected :(, as shown below:

I have just downloaded this image and tried it with the Beta. I applied the distortion corrections and it seems to have straightened the verticals at the expense of imposing a pincushion shape. However the image is too bright, especially the foreground:

I thought I would try a Levels Adjustmentbut the histogram was well spread out so it had no effect. I then tried Nik HDR on the single image:

This certainly improved the range, but the histogram gave scope for Levels Adjustment:

An improvement, but there is a curious blue colour cast in the vignetted areas.

Conclusion: Affinity does not automatically correct the lens barrel distortion and there seems to be problems with the highlights.

Hi all,

I think the reason why we do not do lens correction is the actual name: On our list, we have it as Sony DT 18-135mm f/3.5-5.6 SAM, and yours is Sony DT 18-135mm f/3.5-5.6 OSS . AS far as I can tell, there is a difference between OSS and SAM, but I could not find any difference between the 2 lenses. They seem to be the same lens ?! Correct me if I'm wrong 

However, if you change the RAW engine to Apple RAW in Develop Assistant, they perform the auto-correction :)

They are not the same. The one with OSS is much newer than the other and they fit different mounts.

That solves it then. Thanks :)

This inspire me to use Apple embedded software - Photo, this software perform auto-correction and I can do some basic adjustment as well :0
