I am new to Lightroom, and with windows ten, it is difficult to find features. I have a trial versi9n of light room, and I think I found my photos, that I would like to send to a print company, I did not see any where how to do this, or is this not a feature of light room. Thank You
Use the Export feature in the Library Module. In the Export dialog, choose JPEG and sRGB color or another if your print company specifies something else. Export to a folder on your computer hard drive. From there go outside of Lightroom to your Internet Browser and send the JPEG files to your printer company.
If you do not understand all the options in the Export dialog, come back with specific questions. I suggest you spend some time watching the videos on Adobe Lightroom tutorials | Learn how to use Lightroom CC or elsewhere on the Internet to better understand how Lightroom works.
