Have not shoot anything with 21mm for long time, but this image made me want to do it... the other was rather boring with no far-near dynamics.
Apple Aperture settings
Processing: (little simplified but these would be steps if I would do all manually and skip some file handling relevant issues)
1. Import RAW to Apple Aperture and use same settings as in picture above
2. Export 16-bit TIFF in AdobeRGB
3. PhotoShop -> USM 15%, 40px (adds local contrast)
4. ImageMagick -> downsize to 1280px by command "convert input.tiff -define filter:filter=Lanczos -resize '1280x1280' output.tif"
5. PhotoShop -> change to ICC profile having gamma 1.0 (this is the key, don't do 250% with gamma 2.5 it won't work) and USM 250%, 0.2px and convert to sRGB and turn to 8-bit and save as TIFF
6. ImageMagick -> convert TIFF to JPG by command "convert input.tif -quality 92 output.jpg"
7. restore original EXIF information to image with exiftools command "exiftool -tagsFromFile original_from_aperture.tiff output.jpg"
In order to study what process steps 3 (local contrast) and 5 (minor sharpening of edges) open these 3 images to separate tabs and switch between them:
Added local contrast at full size
minor sharpening to edges at final size
This may sound very complicated and difficult. However by scripting I have made this very easy and fast for myself. Steps 1 and 2 took ~40 seconds. Step 3 and 5 are PhotoShop droplets and takes ~10 seconds. Steps 4,6 and 7 I have automated (I have virtual machine running Linux, in which I have crontab processes monitoring directories and they almost immediately process images coming to the directories) as well taking few seconds each.
So whole process takes roughly 2 minutes when including thinking time involved in the process. Brain usage is needed at:
- step 1 (Apple Aperture settings: wb, recovery, blackpoint, vibrancy are the ones I usually use - this image was so underexposed that had to touch exposure, shadows and mid contrast)
- step 3 (to choose which of the local contrast droplets to select OR no local contrast at all - this is not needed for 90% of photos)
- step 5 (to choose which kind of minor edge sharpening is needed - this is my default but if I don't like results I have few other variants as well)
