I'm still fairly new to Affinity but I have looked through every menu and have been unable to find it. Please forgive me if this is already built in. Otherwise:
Please add the ability to create fake lens flairs (similar to Photoshops: filter-render-lens flair). I'm sure this feature has been requested before but hopefully it can be implemented soon. I know that generally in photography, lens flair is looked down upon and is usually not desired. In fact a lot of photographers probably use Affinity to remove lens flair but of course Affinity is used by more than just photographers.
I work in the architectural visualization field and the main objective of my job is creating renderings that look as realistic as possible. Part of that realism is being able to make the rendered image look like it was shot with a camera which means adding depth of field and lens flairs where appropriate.
I'm sure there are others in need of this feature. It would be awesome if this could be built right into Affinity and we could have a selection of lens flairs and be able to control their brightness and location in a non destructive way.
Good job on the program. Keep up the good work.
