Perspective Corrections

[mariner]

I am using v2.1.1 on a Mac book pro

Perspective corrections under LENS

For some reason, in DEVELOP PERSONA, when I select VERTICAL the photo moves Horizontally and when I move HORIZONTAL the photo moves Vertically.

What Lens profile are you using? Is it the automatically detected one (if there is one) or one you have chosen from the list?

[mariner]

I am not using any lens profile at all

Is your file a RAW format file that you must develop or something else? If RAW, which format is it (cr2, raf, etc.)?

It is a 3mb jpg file

Well, without being able to test that file for myself, all I can say is I do not have this issue with any of the JPEGs I have that I have tested.

However, it just occured to me that maybe you have rotated the file before entering the Develop persona & that is why you get this. Is that possible?

[mariner]

Very odd

Have just run half a dozen other photos through AF and some react normally whilst others don't.

Anyway I appreciate your help so I will persevere. Knowing how to deal with it is half the answer 😱😄

Thanks again

Have any been rotated, skewed, or otherwise transformed before entering the Develop persona?

Can you post one of your JPEGs that doesn't react normally? Maybe someone can figure out something from that....

OK here is one

Works normally for me in AP 2.1.1 on my Mac.

Hi @mariner,

Sorry to hear you're having trouble!

I suspect this may be due to the metadata / orientation of certain JPEG files you are editing, though when uploading these directly to the Forums, this metadata is likely being list and the orientation reset - hence myself and R C-R are unable to replicate this issue currently.

Can you please try attaching a copy of one (or multiple) or the images that exhibit this behaviour within a .zip folder, such that the metadata will remain untouched during the upload process?

It may also help for us to see your exact workflow when this issue occurs, so a short screen recording displaying your steps would also be appreciated.

If you're unsure how to take a screen recording, please check out our FAQ linked below - 

Many thanks in advance

OK thanks - here is the zip file

Incidentally both photos were taken with the same mobile phone - Samsung Z3 Flip

Many thanks for providing those for me!

I can confirm this is due to the EXIF rotation for the image - the plaque image shows that the EXIF Orientation is Right Top:

Whereas the ship image uses the expected Top Left for the same EXIF value.

I believe that the Affinity app should be automatically accounting for this difference in the Develop Persona when using Lens Correction, therefore I'm getting this logged as a bug with our developers now.

In the meantime, if you right click on the layer after opening the image in Affinity and select Rasterise, this will reset the EXIF rotation information. If you then enter the Develop Persona, you should find the sliders work as expected.

I hope this helps

That's great - another mystery solved.

Appreciate your help as I wouldn't have known that.

Many thanks again 😄😄

FWIW, for the SM-F711B camera file, on my Mac in AP V2 in the Metadata panel's "Detail" section I see "Orientation" listed as "Horizontal (normal)." (see below)

There is no orientation info listed in the EXIF section of the Metadata panel.

OTOH, XnViewMP on my Mac in Properties > EXIFTool tab > EXIF lists "Orientation" as Rotate 90 CW" & in the EXIF tab as "right-top (6)."

So ... 3 different displayed values for the Orientation metadata key & while the 2 from XnViewMP are essentially saying it is the same orientation, I suspect AP V2 is not reading the value for the Orientation key correctly (or at all?) in part because the ship JPG shows the same Horizontal (normal) value & it behaves normally.

So maybe this is the source of the bug in AP?

EDIT: BTW, as best as I can tell in AP V2 every one of the JPEG files on my Mac that include a metadata Orientation key list it in Details as Horizontal (normal) so I think AP 2 just ignores that key....

I'm not particularly au fait with metadata, however I think your understanding is correct - it appears as though this is not being correctly interpreted by Affinity causing the issue OP reported.
I think the value is being read to some degree however, as if it was totally ignored I would not expect the develop lens options to be flipped or changed at all, based on the EXIF of the image.

In either case, the issue has been logged and I'm sure our developers can pinpoint the exact reasoning behind this
