| HI:
|
| I have about 20 photos (tripod mounted) that I'd like to blend. I'm
| running Linux Mint 19.1 and I know that my laptop, having only 4gb ram
| at the moment, is rather weak but let's just go with that.
|
| I have tried something similar in the past and it failed so I moved on.
| I was exporting from darktable into PNG format and then importing as
| multiple layers but I'm wondering if, because JPG files are smaller (not
| as good quality as TIFF or PNG even tho I set export quality to 100%),
| would my system handle these images better in JPG format?
|
| Alternatively, if I have 20 images, could I blend 4 groups of 5 at a
| time, then blend the 4 groups into one image, would that be a suitable
| compromise. Yes, more steps than blending once but if the result is
| similar, for the sake of my system's limitations, might this be a
| reasonable alternative method?

if you're using any transparency, as "blend" implies, you'll need to use 
png -- jpegs don't do transparency. also, png is or can be lossless, 
unlike jpeg.
