Making a map bigger in PS, need help

[Ghorgor Cram]

Hi all,

A little while ago I made a regional map using PS4. I still have all the layers in my .psd document. The map is about 2*2 letter sheets.

I want to make a bigger map using this map as a base. IN other words, the map actually covers sheets 1,2,3,4 and I want to add to the PS 4 document blank sheets 5 to 16 so that my larger continental map will be an exact fit with my smaller regional map. Is this possible at all?

5 6 1 2
7 8 3 4
9 10 13 14
11 12 15 16

Thanks

Marc

go to images>canvas size - click on the top right square where the arrows are. Then double the numbers in both height and widht - presto !

Lol presto indeed, deceptively simple when you know about it.

Thank you much
