Having used DSS for over twelve months without a problem, why oh why is it not playing ball now?

Over the past couple of weeks I have tried stacking varies sets of pictures with and without darks, bias and flats, the result is always the same (see below for example)

 Have uninstalled DSS and reinstalled, I have gone back to version 3.3.2 nothing changes!!!!

QUICKLY PREPARED EXAMPLE, default settings.

This is a stack of just 10 light frames with no darks etc. just to give an example but the results are are always the same shape regardless of quantity of images or reference frames. The Autosaved TIFF file is no different. 

1) an original frame (Canon CR2 RAW) converted to JPG for display here

2) The result

All ideas and suggestions would be appreciated.

I had these results and started running 3.3.3 beta 47 which fixed things but as you have been using dss for a while without issues, I'm at a loss. It hasn't auto updated or anything has it?

Edit. forgot to say, mine is the 1100d

That is an odd one ! I've never had owt like that ( I'm still using 3.2.2 ) which is not a lot of help to you !! However, I wonder what will happen if you use the sliders in the RGB tab to bring your peaks back ( to the left) into the start of the 'curve' of the adjustment line. It might then show some detail of what is being crushed out to whitish in the grey and white patches.

You say "This is a stack of just 10 light frames"

but the heading in the result says 8, so two have either not been found or are corrupted, it would be interesting to see what the report is after you do the "Register checked pictures", is it finding the right number of stars like what you used to get ? and why it didnt like 2 frames.

Dont laugh at my next bit :-  The raws out of my camera are given very cryptic names and it is not unknown for me to load and tick some pics to be stacked from the wrong folder ! (DSS  having been looking in a previously used folder) !!!

So, is it picking up a rogue frame from somewhere ?

What does it produce if you tick only one known good frame to be stacked, like your single example frame.

Hope I am not teaching eggs ! Just a few random thoughts to be going on with :)

What camera are you using? I know some of the earlier versions had problems with certain cameras and not others. As for the 8/10, I'm guessing that Dave has it set for "best 80%"?

I know when I was having issues, it was only the raws that failed. if I stacked the jpg they came out fine.

Was set to 80% so only stacked 8 sorry my mistake. Definitely using right images, that is why I carefully selected 10 for example. haven,t tried ticking one, trying converting to TIFF first. Thanks for your suggestions.

Camera =  Canon 600D. Correct on the 80%.

Thanks

As above trying TIFFS to see i that resolves.

I had a similar issue with RAW files from a Canon 1100D - from memory the cure was to uncheck the 'set black point' in the RAW/FITs DDP settings tab - I hadnt checked it but somehow it had become checked.

Thanks I will give that a try.

As a test covert the raws to tiffs using DPP  and try stacking them...

Not much wrong with this. Autosave file OK too.

Conversion of 10 CR2's to TIFF in DDP as suggested. Stacked (80% so 8).

Obviously does not like my RAW files.

At least I now have one solution.

Thanks Peter.

Well it's an improvement colourwise but still not the right orientation or content.

This is the same files that were used in conversion to TIFF above.

Thanks again for suggestion. Looks if I am stuck with converting to TIFF.

Or finding the  rar files for a beta version that works...   DO you have anywhere you can upload a couple of the raw files to for people to try with their installs perhaps?

Good thought, See what I can do.

That is good news !

but why does it not now like the raws when once it did, is the next question and cause of lack of hair !! :)

Have you still got the original raws in a folder for those that you did ok once upon a time ?

Before my camera was supported correctly by DSS I used to use DCRAW to convert, it gives you a lot of options/control over how they are converted, beware tho it is one of those cryptic command line thingies !

Thanks. No idea what has changed, certainly not the camera or any other equipment I am using. It started happening just before I updated to 3.3.4 which is why I tried the beta. Would have difficulty in remembering which RAW files I used as they are not kept in sets.

OK I am trying to upload the same files as used in tests above to Google Drive, when they have been uploaded (may be somewhile) I will post a link to the folder and you can download and play with if you have time.

Thanks to all.
