Glass distortion

[sam3]

Does anyone have a solution for removing the stress patterns that show up in toughened glass doors?

[Alfred]

A regular pattern can be removed with the 'FFT Denoise' filter in Affinity Photo, but that may not be appropriate here. If you attach an example we'll have a better idea of what you're working with.

Hi Alfred,

 

I will try your suggestion later, but in the meantime,

please find attached photo in question.

Not sure if the  'FFT Denoise' filter could handle this so you may want to try a composite or some heavy duty window cleaner.

To me, that photo seems like it was taken with a polarizing filter on the camera. One solution might be to reshoot without that filter

You could take a series of images with the polarizer rotated through various angles, from the same viewpoint (with a tripod if possible); then load them into a stack. Tweaking the options could give you an optimum solution. I would stsrt with minimum.

LOL.

It may well not be possible for the OP to reshoot, in which case something like Carl’s composite is obviously the way to go.

So Carl, what have you done to produce this version?

[carl123]

Well, in brief...

I selected just the island and copied it to it's own layer

Then select all the glass panes and delete them from the original background layer

Find an image of blue sky on the internet and put it as your bottom layer

Find an image of the sea and put just above the Sky layer and drag it down until it is level with the island

Tweak and refine as necessary

PS Once the glass panes are deleted you can add virtually any image you want

The right-hand pane needs tweaking a little to reflect (sorry!) what’s happening in the original picture, but that’s probably quite easy to fix.

Thank you Carl, I will do. It your way.

I downloaded the image and selected just the window onto a separate layer. Applying the FFT filter to this made absolutely no difference.

Thanks, John. I suggested FFT Denoise as a possibility before I had seen the photo in question, but having seen it I’m not at all surprised that the FFT filter doesn’t do anything!
