Does enhahcing digital photos reduces quality???

[go4saket]

Hi guys!

I have a habit of enhancing my digital photos (jpeg format) in a image editing software. Does this degrade the quality of the photos???

Thank you.

No ! Never ! It just does what you wrote.
It enhances and improves it.However how you enhance it is really important.

conversion of file to jpg(which is a lossy compression format) or enhancing an image no doubt loses data... the only thing is "how good u make ur loss look".... u can try to improve the look of ur image but changing color/hue/quality affects file size & data.

And the more u save as jpg... ie the no of times u keep saving a jpg from another jpg.. the quality just reduces every time as artifacts invisible to the casula eye... try viweing the images original & duplicate side-by-side carefully.. like in Photoshops SAVE AS dialogue... if seen clearly... there'll b a difference in color.. & location & pixels...

If u want to reduce loss of data..
1. Keep a copy of the original file
or @least
2. Save as some uncompressed format like bmp, tiff or even psd.

Use tiff files instead.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
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.
