A problem with the overexposure in the panorama rendering


Recommended Posts

Hi,

Recently I became a fan of the panorama functionality in Affinity Photo. Unfortunately I came across a problem I don't know how to address and it seems to me a problem with the design of the panorama rendering algorithm.

Here is the problem:

I stitch sone drone photos of quite different exposures, please see an example below.

AP does a great job of stitching the images and to align the non-matching exposures. However, during that process it looses a large part of the dynamic range, especially in the bright areas (in the examples below: around the sun). I have no control whatsoever on the levels applied by the rendering process - the image I receive after completing the panorama lacks most of the information in the bright area and the sunrays, clouds etc. seen in the middle picture are gone and I see no way to recover them in the "photo" nor the "develop" personae.

I would expect one of the two:

either

- a set of colorist tools in the panorama "persona", so that color corrections can be done before the panorama is rendered and becomes a "final" object in the photo persona

or

- that the output of the panorama "persona" is not a final image, but a set of appropriately aligned/attributed layers in the photo/develop personae, so that the user can make further corrections to these layers (something similar happens in the "stack" functionality, where the stacked images are actually layers that one could individually modify if desired). 

 

Or perhaps I miss something? This would actually be awesome!

 

Best regards,

 

Pawel

I don't think you miss something. The Panorma stich feature is straightforward but there is no 'Panorma Persona' so to  say.

The only thing I can think of is prepare the three images first (lowering the contrast for example) before 'panorma stitching' them.

Thanks Aad, I was afraid this is the case. It seems my request should go to the "missing features" board then.

By the way, while it is true that there is no switchable "panorama persona", however actually that's what the panorama post-stitching page is called, see the image attached (this window appears when trying to click any persona button while in panorama window).

Hopefully this is a sign that something is in the works :)

The stitching process over exposes my pencil drawings in a similar way. It stitches then I see another process flash by as Affinity blasts the light areas. Both scans have the same exposures. My copy of Photoshop CS6E makes a perfect panorama without any issues at all. Am using version 1.9 for Mac (Mojave) and am unsure if it has a Panorama Persona option. ( not in Help ) This problem needs fixing. Any luck with 1.91?
