Think about what equipment you have at your disposal. Thankfully, mobile phones and their cameras are getting better each year and can now deliver visuals close to regular camera quality.
In case you are using your phone, you don’t need to worry much about settings. Instead, focus is key!
Remember to press on the part of the screen where you need the focus to be. By doing so, you will be able to use the basic functions of the camera settings.
And remember, depending on the part of the photo you choose to be the focus, the camera will adjust the light in the picture accordingly. You can try around with this a couple of times until you get it right.
You may even have a family camera you bought several years ago for vacation photos and never got to use it. Bring it to the salon and start creating!
Depending on the camera, you can usually use the automated settings as a start and, with time, incorporate more manual settings.
If you feel devoted to photo taking, you can opt for a simple camera purchase. A lot of the conventional camera brands have simple, hobby photography solution that is enough for your needs, without it feeling like a huge investment.
