Hello community, could anyone please help to answer why these photos were not accepted by technical issues. I am the beginner of Adobe Stock and still learning about all of this. Thanks for your help.

Best Regards,

Ricky

photo 1: artifacts. look at the photo at 400%. you will see the artifacts.

photo 2: not level, underexposed shadows and overexposed highlights.

picture no. 3 - I'm not sure, is there a logo on the train? Then it has to be removed.

picture no. 4 is perspective distorted, the highlights are blown out, noise in the darker areas.

Creo que Adobe no admite fotos de 72 pixel por pulgada

I see. Thanks for your reply and help.

It doesn't matter how many pixels per inch, the main thing is that the number of pixels is correct. 4000 x 3000 as in these photos are definitely sufficient.
