Ok. thank you for the answers . And, i understand all of your point. But, let’s get back to original question.
How much quality loss will happen when 300dpi 2048x 1152 pixel image changed into 72dpi 3000 x 2003 pixel in size. I actually tried it in photoshop. And, i imported in AE. And, the photo quality seems still super sharp in full quality and 100% view. or i would say it’s very acceptable. And very usable quality. What i did was wrong? Please answer yes or no and explain why.

Another question is when 300 dpi image imported in AE. How much scaling is possible without losing full quality? If i imported 72 dpi image i will see the pixelation as soon as i increase scale more than 100%. But, when i import 300dpi image i can increase scale to more than 100% and still doesn’t look pixelated. is there any way i can calculate it when i scaling image that higher than 72 dpi in After effects?
