By losing data,slgr... i meant losing the original data...
Editing adds other data.. in the form of more pixels... more color... file info... all xtrapolated/interpolated/manipulated from the original means... so u lose the original data... no movin backward...
It's like selling ur W800i(which u purchased 4 17000/- 1year back) & buying a new N9* for 22000 (No hard feelins
nokianz

). U actually invested 5000 more for a not-the-same thing. [
Take camera=image & cost=size here]
Quality is a perceptive trait. What i find kool.. may not b 2 ur likin... so... u might have actually enhanced or improved ur image... (and mayb added more kbs

) but u r losin data.
I would always advice to maintain a backup.. @least as cds/dvds.
