been searching a while now and no joy with an answer.
So I want to know 2 things.
Is there an option on LR to export 2 different extensions at once?
So a JPG at say 5mb and one at 500k?
Also would I 'resize to' 1024x768 if I was going to use for web?
Hope you can help.
If you do this all the time you can create a couple export presets, one for the 5mb and one for the 500k, with the setting you use all the time and it will just take a couple more mouse clicks to do what you want.
Do some NEF/RAW files not operate if taking below 500k?
I just batch exported about 45 RAW to 500k but only 5 exported saying there was an error?
Is this common?
It is possible to pick a desired file size that is too small for the image's pixel dimensions. Where that line is drawn will depend on the individual image.
Normally if you are picking a max file size, you are also resizing the file to be smaller, like your 1024x768 example above. This size would easily be under 500 kb.
