HEY FOLKS WITH PHOTOSHOP, LARGE ART, AND AN AVERAGE-SIZED SCANNER: Are you tired of scanning a bunch of tiny chunks and then painstakingly arranging and editing them into a larger image? Plagued by seams? Have you heard the good news of our Lord and Savior, Photomerge?
It’s possible everyone already knows about this, and I was just the last one to find out when I did in 2007 or whenever it was. I don’t really spend a lot of time looking for Photoshop tips and tricks because I often don’t even know what could be useful until I see someone else use it, but I am painfully aware that I’m only using like 30% of this program’s capabilities daily. This particular tool was shown to me in a digital class back in art school and it is an absolute dream.
I’m using Photoshop CS5. I am not sure how far back this function goes. CS5 was the version I learned this trick on, and I can’t remember if I used it on my old CS copy or not, so you may have to Google around to see if any older versions sport this feature.
But here is the deal, it is super easy:
- Scan your image in an obnoxious number of parts. Mine took nine sections, basically three squares across top, middle, and bottom. Make sure you’ve got some overlap.
- Take all those images into Photoshop. I like to reorient the images so they’re all facing the correct way, but if I recall correctly, you don’t even have to do that.
- Cruise on up to File -> Automate -> Photomerge
- A window will pop up with nothing in the list in center. Hit the ‘add open files’ button and a list will populate for you of, predictably, all the files you have open. You can take things off the list if you have a reference image open or something, but Photoshop does so much churning and thinking during this process, I usually make sure that only what I need is open, especially because it’s all usually 300dpi. The other settings I have circled are what pop up on default for me, and they have worked quite well, so if yours come up as something else and you try this and things look wonky, come back and try these ones!
- Click Photomerge and then watch Photoshop go to town. It’ll flash and make wacky layers and put stuff in places it doesn’t belong and then give you several progress bars while it cuts and moves and masks and basically does all that shit that you would breaking your back over for hours, just in like two minutes.
- When the photo carnage is over, if you’ve scanned all your parts well, you’ll have a seamless image! You’ll still have to do a little cleanup - my image was a little titled and I had to clean some areas of shadow from the buckled paper, but I’m so glad that was ALL I had to do.
The last two images show the sort of thing that Photoshop takes care of for you. The first one is shown with the top layer highlighted, showing that the clipping mask for blending is on. With that mask off, in the next image, you can see the shadow where the edge of that part of the scan was. Photoshop automatically picked the image that had the most desirable copy of that section and let it show through in the final assemblage.
All you have to do at this point is clean up and flatten. All your original scans stay intact, so if the image assembles with a missing piece, you know exactly what part you need to go back and scan!
Again, don’t know how many people don’t know about this, but I am always so thankful for it every time I make a large piece, I wanted to talk about it for anyone who might not know!
