There's probably other ways to do this, as everyone seems to develop their own unique ways of doing tasks inside of photoshop, but this is how i do it. The concept is simple, but the process is tedious & a bit time intensive, which is interesting in that i am overall a very impatient person, except when it comes to doing something like this.
Get your photos
i set up my tripod; removed all, but one stool/chair.
Luckily my husband was in a good mood & played along. ;-)
Make each photo a separate layer in Photoshop
- Set Transparency @ ~50% to view the bottom layer.
- i had to "nudge" a couple photos a pixel or 2 this way or that way, since my tripod isn't perfectly stable.
- Rectangle tool to remove large areas
- Eraser tool to move in closer, gradually decreasing brush size as you get to the fine details.
That's basically it in a nutshell. Just put transparency back 100% for all layers (obviously). Lastly, i cropped the image to remove excess empty space at the top.
i didn't really plan this out too much. Hubby was already sitting at the table with his laptop. i grabbed dishes from the cupboard & the newspaper as we moved him & the stool around the table.
