CAN I CROP A GODDAMN PICTURE WITHOUT LOSING A TON OF ITS SIZE?
i use the crop tool to crop a tiny bit out of a picture whose original size is 4288x2848.  cropping to 4x6.  seriously, a TINY BIT.  now the picture size is 1728x1142.  wtf?  and ALL OF MY FILES ARE LIKE THIS NOW, everything i've processed. 
please help me.  maybe i need to start cropping to 8x12.  ?
i gotta find me a PS forum.
