3. WHAT IS IMAGE EDITING?
• Image editing refers to modifying or
improving digital or traditional photographic
images using different techniques, tools or
software. Images produced by scanners,
digital cameras or other image-capturing
devices may be good, but not perfect.
Image editing is done to create the best
possible look for the images and also to
improve the overall quality of the image
according to different parameters.

7. SOME SOFTWARES
• ADOBE PHOTOSHOP-There’s no
argument about it — Adobe Photoshop
remains the best photo-editing software on
the market. But unless you’ve
undergone formal training, it’s a difficult
program to master, and an expensive one
to use.

8. • GIMP-Often heralded as the best free
alternative to Photoshop, GIMP (GNU
Image Manipulation Program) is an open-
source application that relies on a
community of volunteer developers who
maintain and improve the product.

9. • PHOTOSCAPE-Apart from basic image
editing, PhotoScape also lets you create
slideshows and animated GIFs, capture
screenshots, and combine and split
images. You can customize your toolbar,
so you can organize the features you use
most, and then revert to the default toolbar
when you want to dig deeper into the
software’s offerings.

10. • NIK COLLECTION-The Nik Collection is
an image-editing suite that comes courtesy
of Google — one that’s now entirely free.
This is one of the most powerful online
tools available, and Google providing it for
free was pretty big news when it broke last
year.

11. • PAINT.NET-Paint.NET features an
intuitive user interface that supports
layers, an “unlimited undo” to back out of
any mistake no matter how disastrous,
various special effects, and other
tools.Paint.NET is able to handle more
advanced photo editing that you’d expect
from Photoshop and other paid programs.

12. • SUMOPAINT-Sumopaint is one of those
“Photoshop lite” image editors that have
sprung up in recent years — but it stands
out by being truly good at what it does.

13. • PICMONKEY- PicMonkey is a favorite
editing tool for amateur photographers
who want to quickly edit their images and
turn them into mini-masterpieces. There
are four primary tools in the PicMonkey
holster: Editing, Touch Up, Design, and
Collage.

14. • PIXLR.COM-Pixlr.com has a tiered
offering that is entirely free. The site
separates its photo editing into Pixlr Editor
(advanced) and Pixlr Express (efficient).
The site also offers a mobile suite so you
can edit photos on a smartphone or tablet
— both iOS and Android versions are
available.
• The Pixlr Editor is more like Photoshop.
It’s a straightforward photo-editing tool that
lets you crop, size, and tweak the image.
