Carrie recommends the following next steps:
I think that you can get started with a photography book for more information. I would say that you should just get started on taking images, whether on a device or a DSLR camera. The greatest challenge with photography is finding what you want to do with your photography. Do you want to take pictures of people or places? How do you want to use your photography? To document your life or to make a living? I am a photography hobbyist, but it gives me great joy learning all that I can about photography to improve the photos that I share with others. I also enter various photography contests.
There are classes offered on platforms like LinkedIn Learning, who have wonderful classes that are easy to follow, but the platform has some expense. I am not sure how old you are, but I would recommend a free online class called "A Year with my Camera". You will get weekly emails with tasks. The only expense is if you want to order workbooks which are available from Amazon. The course begins once a quarter and takes you through 52 weeks of assignments, starting with the basics.
I went to school primarily for digital design, but there were several photography students in the same graphic design classes I took; for classes, I would focus on classes in any range of creative expression as those are the ones that will challenge you to learn different mediums. It sounds like a stretch, but the more well-rounded you are in different creative fields, the better you can hone in on one special facet. Good luck!
