Does my SharpCap .tif file contain colour information?

[Jim Smith]

I have been experimenting with SharpCap and my Altair gpcam3 178c camera.

I captured a .tif file but I am not sure if it contains any colour information. It is attached along with the settings file.

If it does contain information how can I debayer it?

If it doesn't, then how do I capture one that does?

Thanks, Jim

Hi Jim,

           Yes it does, if you zoom in you can see the bayer pattern. The problem you might be having is that you are using compression and some programs ( pipp for instance ) cannot debayer compressed tiffs. I am sure someone with better knowledge on software can help

You can use PIPP to debayer your images from Sharpcap if you had SharpCap set to use RAW 8 or RAW16.

PIPP gives me the attached error. It was set to RAW14.

In sharpcap settings ( general ) have you ticked compress tiff files ? if so, best to untick until you find a software that can debayer compressed files. The image files will be bigger of course but at least you can debayer them

I have now unticked it! PIPP can now read my tif files. Thank you!

RGGB matrix seems to work best. Now I just need to work out why the images have a green cast.

[barkingsteve]

Good to hear 👍  all your pics will have a green cast due to the bayer pattern ( 2 green to one blue and red ) you can use a program like siril ( free )  to remove the green cast or just balance the colour in post processing ( gimp, photoshop, etc. )

Yes. It works. I have used Affinity Photo's white balance adjustment layer. I leave the white balance control alone and set the tint control all the way into the red. Then, I duplicate the layer and the colours now look right.

All I need now is a clear sky to try it out in anger!

Thanks again. Jim
