Batch converting frames in Linux

[spaceman_spiff]

Hi SGLers,

I thought I would share my little batch conversion programme for converting raw frames into jpgs using ufraw-batch. This is useful if you have large lunar/solar frames and want to pass them through Registax (tiff files were just too large!). Just put the programme into the folder containing your raw frames and make a new folder for the processed images, then add the path to that folder into the programme (after --out-path=).

Here it is...

#!/bin/bash

for f in *.CR2;
do
        ufraw-batch \
                --out-type=jpeg \
                --compression=95 \
                --exposure=2 \
                --overwrite \
                --out-path=/path_to_processed_images/ \
                $f
done

Anyway, hope someone finds it useful.

Dan.

JPG is a lossy format and you'll be throwing away image quality. Try PNG instead. The files are bigger but not as big as a tif.

Thanks, I'm not sure if pngs will work in Registax but I'll give it a go anyway.

Wow, png conversion takes ages!
