Batch processing of photos on post-editing

[Stephen Liu]

GIMP 2.10.18 on Ubuntu 20.04 desktop



Hi all,

I have hundreds of film negatives to be converted to digitized files.  I have no problem scanning them and saving them on Smartphone (with/without scan software installed) to negative photos.  After downloading them to computer I run following "mogrify" command lines (ImageMagick command) batch converting them to postive photos.

Code:

$ mogrify -negate *.* (convert negative photos to postive)

$ mogrify -negate -rotate 90 *.* (convert negative photos to postive and rotate 90 deg clockwise)

$ mogrify -negate -rotate -90 *.* (convert negative photos to postive and rotate 90 deg counter-clockwise)

$ mogrify -negate -rotate 180 *.* (convert negative photos to postive and rotate 180 deg)

They work for me seamlessly.  

Regarding Brightness, Contrast, Hue, Color etc. Can they be processed in batch?

ImageMagicks command;

Code:

$ morgify/convert -brightness-contrast 12x34 *.*

12x13 (value of -brightness-contrast, for example)
able to batch converting all photos but there is no preview.

I found BIMP/DBP plugins for GIMP.  They can perform batch process.  

Is there preview provided?
Can they perform batch processing on HUE Color, brightness, contrast, saturation etc. ?

It would be a tedious work to post-editing hundreds of photo, one by one.

OR is there a better solution for me?  Please advise.

Thanks in advance
