So the problem with giving away 90% discounts, esp regularly, is that people then treat the discount price as the "normal" price. Stores that run constant or very regular discounts find that they make almost no sales during off-months and only sales during discount months. So basically the discount price is your base price.
Now people do like to make a saving, but 90% is basically everything of what you're selling. So either you're insanely high on price and 90% off brings it into normal numbers or you're basically devaluing your own product way too much.
When it comes to photography today sale of images as art is not totally dead, but its insanely hard to get into now. There's a VAST wealth of photos out there. It means a lot of legwork marketing to make any sales. The areas where there is still work is having people pay you to take photos - events, weddings, portraits and so forth. Basically when they pay you to perform a service with the output being photos.
ive had no sales in a year which is why, once my site/business really kicks off, i will take the discount down
i do photography cause i love it, im not tryna be one of those people who always charges blah blah.... cause Im not one of those, I just want to see how good photography can be for income, and making the site was genuianly fun af, and it gvve me someting to do

i agree with the last paragraph

, especially wildlife, its soooo hard to get views on insta, or anywhere else that is. Its jsut that the new gen(gen z/me) are always on their phones and tiktok(i dont have socials, my insta is on moms phone, and she doesnt let me go on her phone... and no snapchat), so really no genz/gen a ever see how beautiful the world is, thats my I do this, and thats why i keep coral and wanna do marine biology, to preserve this world, or help to at least. and I think thats why wildlife/nature photography is so important and how it should be cherished!!
i had an old friend, I introduced him to photography(bear in mind this was in the beginning of september 24') I told him what camera to buy. I taught him everything, and after a couple of weeks(he uses reddit) he started saying i was wrong, he used shutter speed as iso, he didnt use iso, apueture, yeah, thats stupid, i will not buy a lens unless it has f/0.4. He did not trust me anymore, he stopped doing photography around me, and he thought he was better than me. his church started letting him do photos(for free) and his church let him help take photos(he got an $100 tip the one time he did it), so he though, WOWOWW!! i can just go around asking people for money! this was when I stopped being friends with him: in about october/november, he went to a little car meet, took some mediocre af photos, and proceeded to give the guys his email and tell them to pay or he wont send them!!!! waaatt.... thats crazy!! I take photos for my fencing club, and they have never paid me, on their insta, no credit is given... and Idc... thats the real thing driving the hobby down to ground imo. kids thinking they are better than everyone and DEMANDING payment!!
bear in mind, he also thinks iphones are better than film cameras, and its specs on paper over sensor size....
