PhotoShop Basics

Notes

• Back up your work ALWAYS and save as often as possible
• Work in RAW-digital negative (1 GB=1024 MB) (1 MB=1000 KB)
• Always work in pixels per inch
• Default print resolution= 300 DPI
• Default screen resolution=72 DPI
• Work in bibubic automatic
• 'Interpolation'- act of computer adding pixels
• History box-records what you have done to the image (20 stroke limit)
• 'Duplicate layer' or create a new layer and name it appropriately as often as you can
• Do as much as you can in RAW before using Photoshop eg, colour balancing, temperature, contrast, highlights, clarity, lens correction ect. 
• Make sure you open as 'Smart object' so you can go back to Camera RAW if necessary 
• When sizing: Make sure 'Constrain proportions' is ticked
• A3: 42width  |  29.7 height
• SHARPEN SIZE AND SAVE LAST 
• The less you resize the image, the better.
