How many platforms there are That I can sell photos taken by me. (30$) Hello! Thank you for having interest in this topic. Personally I like taking picture of landscape. And also video if I have a chance. and as I know, Every pictures in online, that posted, have copyright on their own. And in some cases you can even sell it to certain websites. And I'm pretty sure some people have gone through the same difficult process questioning. So here I'm asking a few questions. Question 0. Have you ever made any money or succeeded to monetize your pictures/videos? :) Question 1. How to claim the picture that you've taken is yours? What's the way to claim your own right on your own picture? Question 2. There are many many pictures in online, If someone just copy and paste or Save it in their hard drive and re-share it to somewhere, It's pretty hard to claim my right and It's picture orginated from me. How do you prove that the picture you've taken is sheerly derived from you when such cases happen? Question 3. If I sell my pictures to an online platform, and they pay me, How do they exploit my picture to monetize it? Question 4. in which and which websites/service/platform can I sell the pictures I've taken by myself? Question 5. What's the general preparation to 'monetize' your own righted Pictures and Videos that you've taken? Question 6. If you have any experience monetizing such contents by you. How much was its monthly income and in order to achieve such income, how many quantity have you sold your picture ? Question 7. If pictures/videos could be priced, What kind of picture/video get valued the most? and which type of one get valued lowest? Eseential Note 1. I know that for now, the budget is quite low. for this one project, but only if you prove what you've experienced and your knowledge thoroughly, we will have much bigger project to follow up. Remember this is only about concept questioning and more about discussion with someone with same scope and observe. (It's pretty rare to find someone observing the same ground) Note --- It's not enough just by your text explanation, This is oriented in-depth discussion with someone who has ACTUAL EXPERIENCE. and since its question if quite abstract, I respect the real-experienced knowledge even more. So please don't think about tossing a few simple, soulless words without any thinking or knowledge or experiences. So far I've seen So many of people trying to just toss things that they don't even know or understand, It's so easy to spot if you've got real professionality or not. In here I need actual deep discussion and advice. if you're introducing something valid fact, then please screencap real-existing examples of your response :) Thank you for reading! Have a good day and bid me if you think you can complete it. Anytime ! And I am willing to respond very quickly to explain more what I exactly need. also, if you can really make it out well this time in this project, I will promise to carry out further projects with you. Thanks alot.
