"absurdres" at the dimensions it specifies would more suitably be "veryhighres"
a proper 4k tag might be useful (for those with limited search terms).
"incredibly absurdres" would more appropriately be "printing res". it's only "absurd" if it's useless, but resolutions that high are actually needed for good printing.
...and it'd be nice to see low quality large images (scanner noise, blurry etc unprocessed scans) tagged as such so they can be excluded from searches!
