Hard to tell without seeing a screen shot of the Export dialog window and knowing what size and file type you were exporting to before.
Drop the Quality down to 80%.
What size, in MBs, were the exports before you made the change?
Also it is best to show the whole, complete, dialog box with all the sections expanded, except the Video section (that is unless you are exporting a video), and the dialog box filling the whole screen top top bottom.
Yeah you had the quality dialed in lower or the option to Resize the image down to less pixels, "Image Sizing" section, or the "Limit File Size To:" part of the "File Settings" section set to reduce the size in MBs.
IIRC neither of them are checked by default with a fresh install of LR and the Export dialog windows being opened for the first time.
The size in MBs is also dependent on what is actually in the image, the sense. An all white image would be much smaller in MBs than one that had tons of activity in it.
Hi guys, I had a similar problem exporting made my files to the lower end of 2mb was very low.
I noticed in my case if I removed the original file it was exporting at lower mb but putting original file back it then exported at the higher mb.
For instance file img_1.cr2 raw size 22.4mb exported without original file = 2.3Mb
but with the original, it was exporting it to 11.5mb just with that it was already a big difference
hope it helps
Exporting any file in LR creates a separate, New, Other, file from the original and does not change the original file in any way.
So just Export it again with a higher Quality Setting.
