The latest entry in my iDevBlogADay Photoshop for Devs series, I’ve crammed in as many tips as I could about using layers in Photoshop.

Helping iPhone developers hate using Photoshop a little less with simple tricks that make workflows more efficient. View the rest of the screencasts in the “Photoshop for Devs” series.

• What am I clicking on? (or: why double-clicking on a layer seems to do something different every time)
• Create a new layer
• Move & select layers
• Transform layers
• Group layers
• Duplicate layers
• Duplicate layer effects
• Merge layers
• Fill layers with a colour
• Lock layers
• Layer opacity
• Layer blend modes

Recorded, edited and uploaded with Screenflow.
