I'm just getting into photoshop and photography and I needed some help. In photoshop how can I addd the lines and shapes over a picture as seen in the following images below?
I moved your post to the tutorials thread In the future if you have any PS questions, please post them here. You can also find quite a few tutorials on the first page.
As for your question, I would do it with the pen tool (although if you are a beginner it may be easier to use the brush tool). If using the brush tool I would create a new layer over the picture layer and just draw the lines. If you need more precise instructions I can make a little tutorial for you in a few days
