How do I grab a jpeg from a layer and open it in its own PSD document, so that I can crop and save how I want? In the attached image, I would like to have the jpeg in the highlighted layer (without the clipping mask) in its own document so that I can edit it as need be.
If you want to keep the layer linked to your current document:
Use Smart Objects. Right click your layer and click Convert to Smart Object. Double clicking the Smart Object layer will open the image in a new tab for you to edit and automatically update the layer in the original file.
If you actually want to save it to a new document separate from the original:
With your layer selected, right click the layer or click the dropdown of the layers panel and select Duplicate Layer...
In the Duplicate Layer dialog select New under 'Document':
- Method 1: Smart object
Right-click the layer and choose 'Convert to smart object'. Now double click the layer and it will open in a new doc. Any edits you make and save will be visible in your original doc.
- Method 2: Duplicate
Right-click the layer and choose 'Duplicate...'. In the dialogue box that appears choose 'New document'. Voila.
PS: doing this from memory but I think it's right.
