Resize Document Before Editing or After is Ok

[artofmtl]

Hi everyone, I want to resize my picture by making the document a little bigger. So my question is « Is it better to resize the document before adding layers or it does not matter if you do it after development ». I have done after all the settings and everything looks good but I would like to have your opinion. Thank you

I always resize, if needed, as one of the very last steps prior to final export. The only "later' step would be a slight sharped if resizing killed the sharpness.

It depends on many factors, mainly the

• use case for the resulting image (large photo print, web, …)
• the quality of source image
• the type of edits you make (e.g. adding layers, what layer types).

if you are ok with the results from your current workflow, go for it.

Otherwise, just give us an example ane exppain what you want to achieve or improve

Enlarging raster images via software will always result in loss of image quality. Sometimes it will not be noticed if you are only enlarging by a small amount. That being said, you will want to do the enlarging of the picture. Then make any edits, additions, etc. If you do the edits first, then you will also lose quality of the edits as well as the initial image you started with If you enlarge at the end.

I don't understand what you mean by, "I want to resize my picture by making the document a little bigger". 

A lot depends on what your final product is and how much enlarging is done. I am speaking from a background of high-quality, four-to-6-color offset lithography where enlarging photos is always frowned upon. When ever I was forced to do this, I would always get a knot in my stomach. To meet deadlines you sometimes have to do what you have to do.
