ha try that for regular size

yep, irfranview does the trick, most scenery shots can get around 70-80% on the slider, and aircraft get 85-90%.
but doing a sunset with a colorful jet (eg, zip air, or the Spirit MD80 10th aniv.) leaving chicago, takes a nice toll on the picture, the slider was at 20%. the picture basically isn't worth it if you've gone below 60%. lines and discoloration appear, destroying the picture.
