How to develop photos smaller than 13x9, 15x11...

| The fork is just there to indicate the size of the photos |
Important: The shell script shown below does not touch the original files (it copies and rotates them). However, I don't give any warranty that you don't lose or ruin your original files, so make sure to have a backup!
Prerequisites
- A set of JPEG images (optimally the same aspect ratio in order to get a seamless montage)
- An installation of ImageMagick (the executables have to be in the
$PATH) - A bash-terminal
How to do it
- Move all the JPG files in a directory
cdinto this directory and create an executable script with the content from below- Execute the script and wait
- After that, the subdirectory
generatedcontains the files you might want to upload to your online photo service
#!/bin/bash g=generated t=$g/tmp mkdir -p $t ### STEP 1 - cloning/rotating the file to 'portrait' ### into the temporary subdirectory(0.jpg, 1.jpg, etc.) i=0 IFS=$'\n' for file in `find . -type f -iname "*.jp*g"` do echo "rotating file $file into $t/$i.jpg" convert "$file" -rotate '90>' $t/$i.jpg let i=i+1 done ### STEP 2 - take 4 JPG files at a time ### and compile them into new 2x2-images i=0 nroffiles=`ls $t/*.jpg | wc -w` let nrofiterations=nroffiles/4 while [ $i -lt $nrofiterations ] do ## helper variables to access file names let f=i*4 let a=f+0 let b=f+1 let c=f+2 let d=f+3 echo "creating a$i.jpg ($a.jpg $b.jpg $c.jpg $d.jpg)" ## compile the 4 separate images into a 2x2-grid. ## please change the parameter 768x1024 if you ## don't have a 3:4 aspect ratio montage $t/$a.jpg $t/$b.jpg $t/$c.jpg $t/$d.jpg -tile 2x2 -geometry 768x1024 $g/a$i.jpg let i=i+1 done ### remove the tmp directory rm -rf $t
The images created by this script look somewhat like this one (individual pictures taken from http://www.freeimages.co.uk/)
Not very advanced stuff, I know, but I think it's a nice combination of some handy tools to make a nice present.
P.S. 1: I know that there are more elegant ways to write the shell-script, but for my purposes and skills this was the quickest way to go.
P.S. 2: I think the 7.5x5.5cm format is optimal for a flip book. Wouldn't it be easy and fun to create your own flip book story with the continuous shooting mode of your digital camera?
