I wanted to isolate this lesson by itself because it’s so important and gets people every time. Before you begin any project in Photoshop, be sure to create a new document by going to “File” and selecting “New.” Set your length and height to whatever dimension and units you want it to be. But the next step is the most important:
Resolution for print projects is 300 dots per inch (dpi).
Resolution for web projects is 72 dots per inch (dpi).
The explanation behind these numbers get pretty technical, so just know these numbers for now. Aside from that, I recommending working in the RGB color mode, which should be the default for new Photoshop documents.
So, in summary, these are the steps:
- Set your output length (the length of the printed document or web image) and set your units (pixels, inches, etc.)
- Set your output height (the height of the printed document or web image) and set your units (pixels, inches, etc.)
- Set your resolution
- Set your color space (usually RGB)
