Hello. I need some guidance here. I'm getting into photography and am using Lightroom. I'm a little confused about sharpness when it comes to zooming in on an image. In order to get large prints from my photos and still have them look sharp at a large size printed out, how far zoomed in in Lightroom does my image still need to appear sharp to me? I hope this makes sense. I see in Lightroom that you can zoom in 1:1, 1:2, 1:3, 1:4, 2:1, 3:1, 4:1, 8:1 and 11:1. At what point is it ok for an image to NOT look sharp when you're REALLY zoomed in a lot and still know the print will look sharp when printed large? Thank you!!
