Photoshop is a raster graphics editor developed by Adobe Systems for MacOS and Windows. It was created in 1988 by Thomas and John Knoll and has become the industry standard for raster graphics editing. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing, and color models like RGB, CMYK, and spot color. This document provides instructions for A Level Photography students on using basic Photoshop techniques like cropping, brightness and contrast adjustments, color balance, and photo filters to subtly edit photographs. It recommends experimenting with these tools on 1-2 photos and creating annotated double page screenshots and enlargements to show the editing.

2. Photoshop is a raster graphics editor
developed and published by Adobe Systems
for MacOS and Windows.
Photoshop was created in 1988 by Thomas
and John Knoll. Since then, it has become the
de facto industry standard in raster graphics
editing, to the point that Photoshop has
become a generic trademark leading to its use
as a verb such as "to Photoshop an image,"
“Photoshopping" and “Photoshop contest",
though Adobe discourages such use.[5] It can
edit and compose raster images in multiple
layers and supports masks, alpha compositing
and several color models including RGB,
CMYK, CIELAB, spot colour and duotone.
For your A Level Photography
understanding how to subtly
edit your photography and be
experimental with your editing
to explore a topic is really
important. This week we are
going to show you basic
Photoshop techniques. If you
are familiar with Lightroom you
can also use this for editing but
this is not vital!

3. DPI stands for ‘Dots Per Inch’ which impacts
the quality of your Photographs printing. In
Photoshop we look at the PPI of the image
which stands for ‘Pixels Per Inch’. Your
Photographs should ideally be 300 PPI and
should be no smaller the 100 PPI. To see what
resolution your Photograph is open your
Photograph in Photoshop. Click the “Image”
menu and choose “Image Size.” Choose
“pixels/inch” from the Resolution drop-down
menu if it is not already displayed by default.
The number in the Resolution box is the PPI of
the photograph.
