Yes you can do this. The only issue is at a portfolio showing to a client and if they say “was this a job for Hugo Boss” you obviously can’t say yes. You would say its a test shoot. I actually got a job with a fashion brand by doing this, i got some high end clothing / footwear from some friends shot it on various backgrounds at home to fill out my portfolio with more product images - so it can work!
Photography
A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
yeah, you should be good as long as it's for personal use and not for commercial gain. plenty of photographers do personal projects with brands and products they like. just make sure not to use it for commercial purposes and you should be fine.
A lot of photographers do it, I don't think it's a big deal for big brands as long as you keep it clean, but it can come off as disingenuous, I wouldn't focus to much on brands, but more on what you are capable of doing creatively.
Imagine you did a shoot with anyone. They are surely going to be wearing branded clothing. You would have to blur out the brands for every shoot you did. That would be crazy.
