Try :
1. In AP, when you want to finally save in jpeg, go to left top FILE>EXPORT to open EXPORT SETTINGS box.
2.First select JPEG. Then in Resample, select Bilinear. Quality 100%.Then click the More box.
3.In ICC Profile, scroll down to bottom and selece SRGB.
4.Now close the box once and then click Export.
Now you will have a big jpeg file.
Go to http://luci.criosweb.ro/riot/?ref=RIOT
use the RIOT utility to resize the created jpeg file to desired size and quality. If you keep quality
to 70 or above, there wont be any significant visual difference. I think facebook allows upto 2048 longer side
and a max of 400K per file. If you go above about 400K or 2048 longer side, FB will again cut the file.
I have noted softness issue in AP JPEG output when quality is kept below 100%.
