Issues with resolution help!

[radki1088]

I have been using a canon rebel sl2 to take my photos and I use Lightroom classic for editing. I recently did an engagement shoot for a couple and while my photos look beautiful in light room and I exported with 100% quality and 300 ppi when I or the couple have downloaded the images the resolution on several (not all) are so low. I used enhance to super resolution and I am going to attempt to export them again, but is there a way I can avoid this in the future? This is so stressful! Is it how I'm shooting the image? How I'm editing? I hardly cropped anything in the photos while editing. Is there a different setting on my camera or in Lightroom I should change? Please help!

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.

Show us a screen capture of this. Please use the "Insert Photo" icon, do not attach files.

300 dpi does not mean anything in terms of quality. The total number of pixels is what counts. Did you crop these images? Did you resize them in the export dialog?

There is zero difference in a document that is 1000x1000 pixels (as an example) at 72 dpi (PPI) or 720 dpi (PPI) or any such value including 300 PPI. All are 1000x1000 pixels and the dpi/ppi is simply a metadata tag. 
This very, very old primer on resolution still seems necessary to post, this may help in understanding the importance of working in total pixels (WxH):

Two things will help us figure this out:

1. A screen shot of the Export dialog box settings you used in Lightroom Classic, specifically the Image Sizing section.

2. The pixel dimensions (height and width in pixels) of the exported files.

It is true that 300 ppi alone doesn’t tell us enough, that’s why I’m curious about the two things above. For example, if an image is 300 ppi but it was exported at only 900 pixels wide by 600 pixels tall, then its maximum print size at 300 pixels per inch would be 3 by 2 inches. So we need to make sure the Export settings weren’t set up to limit the pixel dimensions in some way.

Where are you downloading from? (or visa vera's, where did you upload to?)

How are you downloading?
