i've spent the last few months making some spray cans as props for a scene im working on.
the labels were captured using photogrammetry.
the metal parts of the cans I manually retopologied. so I've got a pretty good work flow now.
a few of these were cans I found floating in my local river while kayaking.
3 of them were done by someone sending me a turntable video of the can being rotated and then I took screenshots from the video, with only point of perspective, it wasnt the most ideal stuff for photogrammetry, but I found that its better to use 700 screenshots instead of just 40 etc. and I got a pretty good quality scan of the label which is the only important bit I needed.
one of the cans a professional friend photographed for me in his studio last year and I had already modelled it, but I re did it in my new work flow and improved it compared to my previous model and I was able to see limitations in the photos they sent me.
finally a friend has given me 2 bags of vintage spray paint ,stuff 'obtained' back in the 1980s, for exmaple one of those cans of Marabu paint still has a Deutschmark price tag on it! if you are into spray paint you will be impressed at that.
so if the weather is ideal for photgrammetry, a bit cloudy, from around 2pm I can take photos at the rear of my house and get a good diffused northerly light which perfect for photogrammetry, I use a bit of white card for an infinite background and as the can is circular its pretty easy to just manually rotate the can instead of using a turntable or a 'lazy susan', if I dont have enough photos and the model is coming out looking 'a bit crap' I just take notes of what bits are looking shit and I take more photos, of that area, maybe another 50-80 photos.

that time I manually draw the labels using Inkscape, it took a while but ask i wanted stuff which looked really neat and spotlessly clean and photogrammetry cant quite do that.

today we had the right sort of weather/ambient light but I was feeling shit so i did some more photography, 150 photos of one can, and it came out shit, so that was a waste of time!<br>
(sadly) i think they painted over it, smh it was really amazing and an achievement that was beyond impressive to me.
Just wanted to share that and maybe it gives people who work in games with trains and tunnels some amazing ideas for some kids playing their games, to make them feel in that moment as i felt in my younger years. Anyway congrats, look forward to more.
