Focusstacking with Raw

[Christoph O.]

Hi Guys,
I've tried several times now to process Affinity Photo Raw files into a Focusstack. 
First, the program always showed that my memory (16GB) is too small and now 
the program crashes right in the middle without comment.
Otherwise everything works, but that is annoying.
Please, someone has an idea what I have to hire, so it runs around?

A few questions:

How many images are you trying to stack? Loading large numbers of raw files may be straining your system resources.

Have you tried developing the imges first and saving as jpegs, then loading these into the focus stack? This would put less strain on your memory. At least one major focus stacking program relies only on jpegs.

At which point did it crash?

Did it load all your files? Did you get any progress information?

What is your operating system?

How much memory do you have? (It helps to put this information as a footline to your postings.)

What kind of raw files are they?

What camera did you use?

Hello John,
Thank you for your answer.
I tried different numbers of raw files. There were also 300 times. Maybe that was too much. Currently I had tried it with 34 shots. 
There was also the first time the commentless crash of Affinity.The crash always occurs after a few minutes. In the case of the 300
pieces stack it might be 10-15 minutes. At 34, it was 3-4 minutes.
The used camera was an Olympus Pen-F. In addition, I use the Lumix FZ1000.
My PC has a 16GB of memory and an I7 processor of the 3rd generation. I use Win7 64.

I would guess that you are pushing your resources too far, even with 16Gb.  One thing you could try is to monitor your memory usage as the stacking proceeds. Use the Task Manager.  If it approaches your memory limit, it would also indicate you are pushing it too far

It is worth trying to stack jpeg images. If this works, then that would probably confirm it is a memory issue.

Could I ask ask you to reduce the length of your lines in your postings. Your long lines are difficult to read, and I need to scroll sideways.

Hello John, 
I thought Affinty can handle raw files as well. 
Okay, if that's not the case, I'll probably have to do it again with Jpeg. 
I have discovered that there is a super fine jpeg setting on the pen-f (LSF),with a very low compression, which I will use from now on.

In this forum, structuring a post is quite difficult. Excuse me!

Thanks a lot for your Help!

Yes, Affinity can handle raw files, but in moderation. I have had no problems with loading a dozen or more raw files into a stack, but I do acknowledge that there are some situations (such as macro- and micro-photography) where you need to stack many more. You need to acknowledge that the images from the raw files cannot be stacked until they have been developed, and this is probably one reason why it is taking so long.

The scroll bars in your message helped, but could you possibly just insert some return/enter keys after around 100 characters or so?

Hello John,
Since my first post I wrote the lyrics so that I did not have to scroll on my monitor. 
We could finish the topic. I will continue to stack with Affinity with Jpeg. 
If that's not enough for me, I'll probably have to save on Zerene Stacker or Helicon Focus. From the former I know that it can stack Tiff.
Thanks for your help, see you!
