The issue with Prisma (and the other commodity ML style transfer apps AFAIK) is that they generate low resolution output. It’s disappointing because I like some of the results but they are more fun quality than production quality. I have printed Prisma output as big as 12"x12" on canvas after some photoshop post processing and that was pushing it for sure. IMO canvas works pretty well with low res images and the laser is likely to be less forgiving on wood.
I’m planning to deploy my own tensorflow. Style transfer examples are pretty widely available and it will be interesting to use my own training images.
I like what Dan did to that pic in Photoshop. The Prisma filter, not so much. That made it look like someone tried to make a lithograph while on acid, though in fairness, Dan obviously knows a lot more about what works in a GF than I do. My own $.02 as a photographer would be that if you followed Dan’s steps in Photoshop using the original image, you might get better results. I assume that what we see here is a reduced image, and that your original is in much higher resolution. You’d get less .JPG artifacts that way, and some selective application of the blur tool would help reduce the ones that remain.
Although I haven’t received my GF yet, I do have experience converting photos for use in laser engraving on both wood and glass. The operative word is always contrast, contrast, contrast! Subtle gradients and fine detail tend to fall by the wayside. You’re facing an uphill battle with this particular image, because as Shop already pointed out, the beauty in that pic is from color. It doesn’t have a lot of inherent contrast, so adding some is essential, but brings its own set of problems as well. I think JBManning is right. I have a gut feeling this will end up looking better on slate or glass as opposed to wood. But I look forward to seeing it one way or the other.
I was just watching a video about using laser engravers for cutting/ablating heat transfer vinyl (NOT PVC) and they demonstrated using 1-Touch Laser Photo for simply converting a full color photo into something ready to be laser engraved. It’s from Universal Laser but they said it can work with any laser. The following site shows examples of it used on a number of substrates including wood, leather, and stone.
I haven’t seen a price for it but there is a 30 day free trial.
Here’s the video that I learned about it from. The whole video is interesting if you are considering using your Glowforge to make t-shirts. The first mention of the 1-Touch software is around 21:00. Some of the better examples of what it can do are at 22:25 and 27:45.
Thanks Dan, that is a nice little tutorial and I can’t wait to try.
Also thanks to the other advice and ideas offered.
Unfortunately I found out just yesterday my forge got a little rattled or something so they are sending a replacement. What is funny is the stuff I have already done looks amazing so I am excited to see what better then amazing is
I know it isn’t a great pic, trying to get better at it, but here are two 4 inch across tests. Wanted to see what the difference light and dark engraves would do on the edit I had on the photo so far. Still have to dial in some things to try and get the weather, but trees look great at least heh.
Depending on the size of the print, the interface might not be able to handle it at the default resolution. (LPI). There is currently a limitation due to buffer size.
You can lower the resolution of the photo, (that helps) and lower the number of LPI that the machine is using to process it to about 195 LPI. That is generally good enough for an excellent render. It sometimes also helps to reduce the physical size that you are printing.
Take the leap and post a new topic on this. We’ll help troubleshoot the issue. @Jules has pointed out the most obvious issue and solution.
Just curious, how much have you been keeping up on the forum and the continuing saga of first prints and such?
I’m still wondering what is the most effective method to get some type of best practices, pitfalls and perils, checklist for design to every new user. It seems that the information provided in setup and first prints is not enough for folks to have more successes than failures.
i try to keep up with the forums, but it’s just full of people who actually have units already. I just received mine and it’s been hard to find a beginner series of videos to get me started. I’ve been in my garage for over an hour and haven’t printed a single thing yet.
Thanks for the support everyone! I just wanted to print out a family photo for my grandma tomorrow, but i think i’m going to have to do some more image work tomorrow. I ran a test on a logo I designed and it’s a few minutes away from finishing. Stupid mistake - i tore off the sticker on the wood.
btw - i totally didn’t read the user manual. I’m a dude. I’m stupid. now i’m looking for videos, so i don’t have to read! haha
