Raw Files

Hi Peter,

There should be color in the stack created by APP. Try to load the stack with saturation enabled (on the right side below the histogram) and set the saturation slider (SAT) to 0.20-0.25.

Maybe you can show a screenshot of the integration/stack made by APP?

Kind regards,

Mabula

Hi Mabula

Thanks for the quick reply, I tried saturation as suggested, didn't make any difference, I have attached to files, one of the original frames and one of the final output.

In my test I didn't change any of the settings, just left them as the default settings

Peter

Hi Peter,

You're most welcome.

So the left one is one of the original frames? And the right frame is the final output?

Both images are not black and white, in the first image I see purple and green, but it doesn't look correct, I agree.

But If the left one is one of the original frames, maybe a wrong CFA pattern is used, did you alter the CFA pattern in 0)RAW/FITS to RGGB instead of default possibly? Try setting it to GBRG (which is the correct pattern for a Canon 600D, DSS uses dcraw and dcraw needs a RGGB pattern for the 600D).

Maybe you can send me one of your CR2 files, so I can have a look myself?

Kind regards,

Mabula

Hi Mabula

No the lefthand frame is the final stacked output (9 frames) from APP the right hand one is the original CS2 File converted to JPG and reduced to make it easier to upload as I have a very slow internet conection here in Tenerife.

I'll have a look at the settings to ensure that it is on GBRG and give it another go

Thanks for the help

Peter

Hi Peter,

Any improvement? If not, please try to send me just one of your light frames, so I can have a good look.

Kind regards,

Mabula

Hi Mabula

I've sent you an email as the files are to big for this site

Hi Peter,

Your camera is designated as a: "EOS Kiss X5", this indeed is the same camera as the EOS 600D, and the EOS REBEL T3I.

This camera model is a tag in the metadata of the camera, and this is the first time I encounter your camera designation (with the Kiss). APP wasn't setup yet to automatically apply the correct debayer pattern for your camera. It now is ;-), so in 1.054 you can leave the debayer pattern on "supported" and it will be correct.

I have all EOS camera's and their Rebel partners implemented, but the Kiss camera's not yet, so I'll try to get them all fixed as soon as possible.

This is now what I see in APP when I load your CR2 file with saturation and the linear image viewer mode (and CFA pattern on supported):

This is similar what you sent me using the GBRG pattern.

We can also check how the data looks like similar to how a Canon camera or software would show it when it interprets the data as a normal photography image. That means that the data is converted to the non-linear sRGB space using a log conversion (s-curve) and we also enable camera white balance. Then this converted data is again shown stretched using the preview filter. I guess this image has more or less the same colors as you were expecting? Or not?

This is normal behaviour. The color calibration after integration should help you in getting correct colors in the end.

Let me know if this clarifies it for you 😉

Hi Mabula

Thanks for that I will have a play around with it and see what happens, when will 1.054 be available for download.

Hi Mabula

Another question, would you process RAW files before stacking or after.

Peter

Hi Peter,

1.054 is out !

You need the raw files for stacking to have the best results 😉 Processing only after integration is the best way to go I think.

Cheers,

Mabula
