Hello, when downloading images there is no choice of size or resolution; I have downloaded images that I have to enlarge to 2 meters but those downloaded have 300dpi but dimensions of 20-30-40 cm and once enlarged are grainy.
If you are downloading small images from various Internet sites and scaling them to 2 meters (78.74 inches), then they will be pixelated. Scaling an image does not change the number of pixels. Changing the ppi (pixels per inch) from a lower number to a higher number does not give you better pixels, just more pixels.
What you are describing is expected behavior.
Downloaded images = Adobe stock as a product?
Adobe stock provides images in the best available resolution. There is no choice of a resolution, because you are always at the best.
40cm at 300ppi = 4724 pixels. Current cameras have higher resolution, so there should be pictures around with higher marks. Those 4700 pixels at 2m will have a density of 60ppx which is not much, but with some post-processing you could get around 100 ppx, which will be enough for 2m prints.
You should describe how you enlarge your pictures.
lionellob97383248 posted to Forum Comments and the post was moved. Do we know the downloading is from Adobe Stock?
No, only guesswork based on "Downloading pictures, no choice of resolution, 300dpi, 20-30-40 cm". When the OP states a different product/program to use, it can be moved further.
Thanks — I didn’t see that, but you might be right!
Good morning, the photos purchased on Adobe stock n ° AdobeStock_260110730 of kb 3537, AdobeStock_210528371 of kb 10068, AdobeStock_82229383 of kb 3003 must be suitable to be printed with a height of cm. 200 and will be viewed from a distance of 50 cm., The site does not give the choice due to the size and size / resolution of these photos are not suitable.
I don't have the possibility to adapt them.
This is the best possible resolution of this file:
That is the best available resolution. If you need mere, you need to enlarge the picture, which is not a trivial task if you want to keep the quality. I do not know about your printing technique but I would assume that 200% enlargement and a pixel density of 100ppi should work if done correctly.
Nb: For a perfect resolution at a viewing distance of 50cm you would need about 175ppi. 50cm for a 2m poster is very near. If you go to an event or a showroom and you see those big posters, you will see that most of the time the resolutions are much less.
If you need higher resolution pictures, you need to select different files with a big enough file size: 13780 pixels in height @175ppi.
