Good morning /p/!

I am not a photographer, but I have a problem and need to learn about distortion/angles and stuff.

I am an ex-fatty and i make progress shots of my body from time to time and something about that bothers me. When i make a shot I put my phone straight between two books or something and activate the timer. The thing is, the closer I am to the camera, the weirder my body looks. When i am 10 feet away, i think I start too look good, when I am like 6 feet away, my hips look incredible wide compared to my upper body. That really bothers me tho, thats why I am asking you people, who hopefully know your stuff for help. Thanks in advance!!!

Your phone is a wide angle lens... the numbers that describe it's focallength will be down near 5-20mm or so
You need some perspective compression, you get this from longer focallenghts.
Obviously a longer focallenght means the camera neds to be further away to fit youin frame too.
Try either a different camera, mounted at half your height and looking almost perfectly horizontally at you (not on an angle looking up or down).
Or try some of those novelty lenses you can get for phone cameras that add some form of telephoto lens by clipping over the phones lens. Those might generally be a little too extreme to be practical though.
If your phone zooms you could also do that, but the resolution will suffer.

Dude, I love you, for your explanation!

Could it also have something to do, that on the particular place, where I put the camera and look the worst, my upper body is completely in the lower half of the pic? Another thing is, that it seems, when I put the phone completely straight, like 90 degrees it automatically broadens the lower part of the picture, like youre photographing a building? Sometimes it seems like that.

Thank you dude!!

Here's a little picture to help you with wide angle lenses. You most certainly have seen pictures taken with a fisheye lens before, they are a extreme version of a wide angle lens and as you know they cause a lot of distortion.
Like >>2606844 said, your phone has a wide angle lens as well, not as wide as a fish eye, but still wide enough to cause distortion.

Look at 35mm and 16mm in this picture, these are the results you get from a phone camera when pointed to a face or any other close object like your body. Depending on the angle of your phone, other parts of the picture get distorted, for example the lower part of your body. Exactly like photographing a building, you are right.

I take progress pics with a portrait lens, you don't have to buy a new camera for that kind of stuf though, just listen to >>2606844

Good luck with your progress bro, we're all gonna make it

Try to take your progress pics in the same light brudi. Soft defused natural light from a window works best

Light is a big part of photography, to emphasize muscles you usually use a harsh top light to create more shadows. If you use different light every time you take a progress pic, you will have a much harder time to make up your actual progress

yeah, light
make it reproducable or your progress photos won't really show what you want them to.
Considering the images you showed I'd just try zooming in a bit.. the bit of resoulution you lose won't be any great loss unless you want to start tracking the movement of skin moles or something.
Also the focallenght of the lens AND the size of the sensor is what will determine your distortion.Around 120mm at 35mmEquiv is what I'd aim for if I was looking to take the ideal forensic body shot. That's a guess mind you, but I'm pretty sure it would be sufficient perspective compression and still not put the camera so far away as to be impractical.

But again.. put the camera at almost exactly half of your height, and pointing as close to horizontal as you can.
