Find a directional source of light
Our eyes are naturally drawn to some things more than others. Big boobs and scantily dressed women are definitely one way to get our attention, but so are bright objects with good contrast.
Proper lighting involves a good quantity and quality of light. Having a good quantity of light means feeding enough information to the camera sensor. A good quality of light refers to having the direction and softness for the desired look.

Dievas Pay attention to the headlights.
What you can try to do is
find a directional source of light and place your subject closer to it. That way, your subject is brighter than most of everything else in the pictures and helps provide subject separation in the photos. Additional points if the light source is bright and large. This will lower the amount of noise in the picture and also provide softer looking light that is aesthetically pleasing on the skin.

Sadly in most apartments or budget hotels, your options for finding good light may be quite limited. With some effort though, you may be able to find a suitable spot. A great way to get this light is from a
window, especially with a sheer curtain that benefits from extra privacy and to soften the light. A table lamp or other household lights may also help provide great directionality to light, but the quantity may be insufficient for most camera phones. If the walls are white or neutral coloured, a small high power torch light can be used to bounce light onto a surface to act as a nice soft light source.
Subject placement
Where we place our subject in the three dimensional world or two dimensional photo plays a huge part as well.

Our eyes naturally gravitate towards the centre of an image. Instead of aiming to capture the whole body in the frame with no goal in mind, try to focus on a point you want to highlight and put it close to the centre of the frame. It can be the boobs, butt, face, skin, jewellery, tattoos, and whatsoever.

shyboiboi Pay attention to the use of leading lines converging to a central point.
When objects are closer to the camera, they appear bigger. So if you want to highlight your session partner’s big breasts, have them lean a bit closer to the camera. What if the subject has a bit of a tummy? Then in order to reduce the size of it, it should be further away. Have your subject turn her belly slightly away from the camera. Every bit helps.
Have fun
Remember there are no rules in photography and art. These are merely guidelines for a better picture. But depending on your intended idea and message, they can be broken for greater effect. Let’s say you have a thing for big tummies, then perhaps bringing the camera lower and closer to it might get you the desired effect even if it is generally not deemed as nice to the general audience. Most importantly, have
fun making memories and enjoying a good bonk.
