If you are going to use being a photographer as a method to isolate women, you are going to need to know how to do that, and have equipment that makes you look like a photographer. Like at least one SLR camera, several lenses, a tripod, and lights.
I'm guessing you do not have any of this now. However, you can start on for free it by learning how to take good pictures. I'm assuming that you have a cell phone with a camera on it. Phone cameras are quite good these days. A friend takes incredible picture on his Samsung phone, but he is a skilled photographer. Phones have fixed lenses and automatically set aperture and shutter speed, which makes it easy to take pictures and reduces complexity. You can use a phone to master two of the vital elements in photography, composition and lighting. Composition is deciding what to include and exclude from a photo and where to place the subject. Lighting should not need explanation, other than learning about how it works and why it will improve the photos you take.
This is the age of the Internet, every book in the world is at your fingertips. YouTube likely has tons of videos on composition and lighting. Make learning the basics of photography your new hobby.
Cameras lose value quickly after they are new. Look around and find out where you can buy used equipment. A place that lets you bring it back within a few days if you are unhappy with the purchase is as important as a low price. As a beginner, an honest business is worth a bit higher price. Nikon and Canon are the best brands. Their equipment lasts and is advanced enough that 3-4 year old hardware, if it is in good condition, is still excellent and should last for many years.
And keep learning seduction; the camera is just an excuse to interact with her. You still have to seduce the girl.
