Question about focus stacking - I'm new to Photoshop

[wm17959]

Hello,

Yesterday I was experimenting with Focus Stacking after watching a video on YouTube. As far as Photoshop goes, I followed the directions as best as possible, but I still have problems. Please see image and notice the blurring around each screw. I'd like to know how to fix this. If you can help I would appreciate it.

Hello.

Are you talking about focus stacking? I don't see any blurring around the screws and they all seem to be in sharp focus. The ruler is a bit out of focus on the upper end. Perhaps you could point out the problem area.

Hello Sam. Yes, I meant to say focus stacking. When I open this image on my iMac the blurring around each screw is more noticeable. You can see it on the ruler behind the screw. I'm wondering if there is a way to correct this with the use of masking layers, but as I said I'm new to this and I have not yet looked into how to use masking layers.

Ahh yes, I now see it when opened in Ps. I was also looking more at the bases of each screw and it's at the top.



If you used Photomerge for alignment and autoblend, your going to have some areas that the algorithm can't deal with..........it's not perfect. The output of the autoblend should have created layer masks on all the image layers. You will have to use the Brush Tool on each layer mask and clean up the "out of focus" areas around the screws points.

I appreciate that Sam. As I said, I'm still rather new to all this but I will look into layer masks and how to use them. This is just a practice exercise. My plan is to use this technique to do architectural photography and other kinds of product shots. Thanks again!
