Adobe Photoshop Tutorials -hints, tips and tricks

Adding depth and a range of lighting...

--------------------
To create more depth and range of lighting in the image, go to image > adjustments > levels and adjust the sliders accordingly. 
Or, to create a separate 'levels' layer to ensure that the original image is not harmed, click the 'create new adjustment layer' button (half moon icon) and click levels.

A separate levels layer can be adjusted and re-adjusted without changing the original image.  Certain elements of this layer can be removed using the eraser tool to reveal the original image underneath.
... or added back in with the brush tool.

What the levels adjust panel looks like. 

--------------------

Getting started...


Ideally, you want your measurements to be in mm or cm if you're working for print, and pixels if for screen/web.
--------------------

RGB colour is for when you are working onscreen, so for web this is ideal. But if you are working for print, you must work in CMYK because this is the same colour mode as the printer. Documents printed in RGB will look a lot duller and inaccurate to the colours onscreen.
--------------------

If the resolution is set high then your document can be printed at many sizes bigger than onscreen without getting pixelated.
--------------------

RGB to CMYK...

This image was taken with a digital camera in RGB mode. This means that the image too, is in RGB mode and so will not look like this when printed. To see what it will look like when printed, go to image > mode > CMYK Color:

Viewing the Gamut warning reveals all the colours that CMYK mode cannot show.

This is what the image will look like when printed.

Adjusting lighting using curves...
