Photography is light
& composition.

A frozen moment in time.

If you can get your head around that, then you will take great photos.

Photography by edgetas
Image information
Generally, photos off the internet are too low in resolution to be used for print purposes. A screen resolution of 72dpi is used for the internet, where as magazine images require 300dpi. Newspapers generally require 240dpi for colour and 180dpi for mono photos.
For optimum results the original file should be supplied.

Photoshop is the 'industry standard' image editor but it is also very expensive. A great open source image editor is gimp. It has many of the same features of Photoshop at the best price possible - FREE!

BASIC ADJUST A PHOTO FOR ONLINE REPRODUCTION
using Photoshop.


Open file -  leave as is (don't colour manage) [OK]

Image[menu]/Mode/RGB Colour

[Ctrl L] for levels

Select  Channel: RGB  from pull down
Adjust  Middle slider so blacks are still black in pic
Adjust seperate R G  & B Channels in same way if in a colour hue on the photo. for example:
To reduce the yellow in your photos, open levels (ctrl + l),
select the blue channel from the pulldown arrow (default RGB) at the top, drag the middle arrow under the graph to the left, but not too far or it will be too blue. You can adjust the end arrows for shadows - to the left and highlights at right.

You can then revert back to the RGB channel to adjust the overall balance.
Generally for RGB, each end should be near the start of where the graph begins, and then adjust the middle arrow, so the blacks are just black, and there's white highlights but still detail.

Intensify colours by increasing saturation [Ctrl U].

Image[menu]/Image size (or use crop tool)

Save as  JPEG      uncheck  ICC Profile:  [OK]
