Fixing a Photo

[Vince_B]

I have a photo of an instrument I designed.  Unfortunately, the person taking the photo didn't tell me that my clean room mask was cattywampus.  This was a significant event in my career and I have tried to fix it myself without success.  I can fill in the background hidden by the bulge, but cannot create a believable fixed mask.  I imagine that there are those here who could easily fix it.  If anyone would like to try, you would have my sincere thanks.

I can provide details on the instrument if anyone is curious.

You could try making a selection of the left side of the face as we view it, copying it (Ctrl+J) then flipping it and aligning to the right. After that a bit of painting on the mask to blend the two and a touch of cloning.

....and yes I'm intrigued by the instrument

I am curious too.

Davescm, thank you.  That was very helpful.

The photo is of the OVIRS instrument. It is a wide band spectrometer, one of the principle instruments on the OSIRIS-REx Asteroid Sample & Return Mission. OSIRIS-REx is currently on it's way back to Earth after picking up a sample from the surface of the asteroid Bennu (aka RQ-36). The dark area surrounded by gold colored stuff on the near side of the instrument is where the MLI (multi-layer insulation) is pulled back from the region where the instrument attaches to its electronic box (not shown). The flat white plates on top are radiative coolers. There are white in the visible, so they won't be heated too much by the Sun. They are very black in the infrared so they can radiate heat from the instrument into cold space.

The part closest to me is a solar calibrator.  Viewing the Sun (which we measure every day) gives us a known flux that we can use to correct for any changes in the sensitivity of our instrument.  Since it was not possible to verify the functioning of the calibrator until we were in space, I gained a few more gray hairs until I heard back that it was working as planned.

Vince,

That's cool. Thanks for explaining.

[davescm]

Thanks for the explanation it was very interesting. That sounds a clever design of the radiators being able to both efficiently reflect and radiate heat. I can imagine the tension waiting to see if the instrument worked!

I've just watched the film clip on asteroid Bennu. Truly fascinating and I love the names given to the formations!

I think the way forward is to take another photograph of your face and replace it – something like this:

That's the way I'd go about it Derek.  We tend to think in terms of 'face replacement' when fixing groupd photographs.  There are multiple tutorials and even some automatic plugins.  Duplicate the lighting angles etc. and take another picture of the face.
