Exporting from LR Classic - Quality and Limit File Size to

[photofan731]

Hi,

Using Lightroom Classic 7.2 and Mac High Sierra 10.13.6

I have not unpdated Lightroom Classic as there were too many issues with it

7.2 has been working fine on export until today

I usually export my original files at full size -5760 x 3840 pixels

Under File Settings - Quality is 80 an Limit File Size to 100 K

Today this does not work, my files end up pixelated

Any suggestions welcome

Chris

If you set limit file size to 100k for full size images, you will always end up with extremely pixelated images because the jpeg algorithm will have to drop the quality tremendously to be able to do this and you will see very bad jpeg compression artifacts that will look like pixellation. 100k is way too small.

Thanks for quick reply

Sorry I made a mistake, after working on the original file I export it as a 'JPG' sometimes cropped slightly or

not cropped at all.

I have never had this problem before today exporting at quality 80 and Limit File size to 100K

What should I set the 'Limit File size to'  when I need to send an image which has  be at least 3 megapixels in size and no larger than 256 megapixels?

As you see I am not good at technology !

The best thing is to NOT use the "limit file size to" setting at all and

just use the quality setting. Quality 80 will always give good results. You

will get bigger file sizes for larger images this way as you should.

has  be at least 3 megapixels in size and no larger than 256 megapixels?

To clarify- 100K is  0.1megapixel.  (1000K = 1 megapixel,  3000K = 3 mP)

So follow the advice from Jao vdL​
