Hi Folks,
I thought for today I’d leave you with a really easy Photoshop Quick Tip that I use almost every time I’m putting together a composite image…

When I’m adding in a new background I like to make sure that it measures the exact same dimensions as what it’s going to be placed into; this way I don’t have to start resizing it later and as a consequence affecting how sharp it is etc…

Doing this is really easy and takes just two simple steps as you can see in this example:

Canvas Size
Ok, so in Photoshop here I have my image of model Steve Lewington that I’m going to work on and this measures 4256 pixels x 2832 pixels:

So, for me to now make up a background that fits exactly these dimensions all I need to do in Photoshop is:

Step 1: From the File Menu, select … New

Step 2: From within the New dialog box, click in the box next to the word Preset and from with the options that appear select the name of the file that you already have open; in this case “STEVE_LEWINGTON” and click OK.

And that is all there is to it! The new document that now opens up in Photoshop will measure exactly the same dimensions; see…told you it was a Quick 🙂

    Also useful to note that it applies the same color profile, which could be kind of important.

    The Cmd-A, Cmd-C, Cmd-N, shortcut does not apply the same profile, and only works if the image being copied is either flattened or has pixel data in all corners, otherwise the dimension will be based on the maximum area required to encompass all pixels on the active layer.

    Since we’re offering alternates:
    Image>Duplicate… (Tick Duplicate Merged Layers Only)
    And at that point, why not simply make it an action. 🙂
