Photoshop: Finding the rule of thirds every time.

This is a short action tutorial for drawing guides in Photoshop that display a rule of thirds grid no matter what the resolution of the picture.

It can be really useful when cropping in Photoshop saving you the hassle of opening the image in something like Lightroom just to crop.

- Open Photoshop (CS2 ,3 and 4)

- Make a new image 800×600 pixels (you could just open an existing photo)

- Press ‘Ctrl+R’ to display your rulers.

- Right click on the ruler and select ‘percent’

- Go to your actions tab and create a new action – Call it ‘Rule of Thirds’ and assign a hot key.

- Go to the menu ‘View\Delete guides’ (this removes any existing guides)

- Now you action is recording select the menu ‘View\New Guides’

- Leave it selected as ‘Vertical’ and type in ‘33%’ then click ‘Ok’

- Create another new guide ‘Vertical’ at ‘66%’

- Create two more ‘Horizontal’ guides (one at 33% and one at 66%)

- Stop the action from recording.

- Right click on the ruler and select pixels (or your preferred measurement)

That is it! Every time you use your hot key or just run the action it will clear the existing lines and create new ones. Because you made the lines in percent, when you crop or resize it will always redraw the correct rule of thirds grid

    This is very helpful.

    I wanted to crop certain images and at least have rule of thirds followed in those :-)
