i would recommend NUMBER_TOKEN but in all honesty i find i get my best results  at about NUMBER_TOKEN to NUMBER_TOKEN photos for something that i can hold in my hands NUMBER_TOKEN to NUMBER_TOKEN for something  about the size of the average adult and just go crazy for anything bigger the overall rule is that it's better to overshoot and not use images than undershoot and wish you took more now yes i know that is a lot of photos but trust me it goes a lot faster than you think and i only go into the hundreds because i really like to keep the details in my photogrammetries with time you'll learn the level of detail that you're happy with and start to see the correlation between the number of photos that you take and the detail that you get out lastly as long as you keep the computer mindset while taking your photos there are no real rules to what distance you should stay at you can even take close-ups of parts that you would like to have extra definition and if you really want to push the envelope and risk it a little you can even use multiple different cameras and lenses but this might affect the overall color of the final texture if you care about that as you can see i usually work my way around in full circles changing my angle of capture after every full circle once i've gone around a few times i then focus on the detail and the awkward to reach spots now if you're interested in following along or you don't have the best weather to do photogrammetry right now down in the description i have a few different photogrammetry image sets free for you to download to get making right now and now that you have a lovely set of photogrammetry images be it provided by me or that you have taken let's look at the program we'll be using which is mesh room by alice vision if you haven't heard about mesh room you're about to be blown away completely free and open source bit of software here that does so much more than just photogrammetry i strongly suggest you go here and check it out we're gonna go to try mesh room now and straight away on their download page you're going to see there isn't a mac version don't worry mac users you can use what i use which is rendero this video sponsor or you can give it a go trying to use google colab now i haven't done this it's quite an involved method it's linked down in the description with that link as well as a video and lastly for everyone you need a nvidia cuda enabled gpu to run this version of mesh room with that said as it's open source someone has created a branch that doesn't need this and that is also linked down in the description now just before you download the version of mushroom that you'll be using hear me out i want to talk about this video sponsor rendero rendero is a cloud computer literally a desktop in the cloud and it's incredible just to give you an idea i'm actually using it right this minute for this video and i have zero lag and i'm in the middle of nowhere in scotland so you can imagine you're gonna have a pretty good connection too they're pushing very hard to creatives because they know that we use a lot of power and we need a scalable workstation and that's exactly what they're providing
