Hello! I am still fairly new to wedding photography. I have never had any issues until now. I have a couple I delivered them there digital negatives to and have had for over a week without saying a word until now. Today I received an email from the groom stating, "We have received our USB drive with all of our photos, however these photos are only 1200x800 resolution. We would like some of these pictures with a large resolution. Is this the native file size? If not, could you please send us the higher definition files?". I am still learning Adobe Lightroom and what, when and how basically to export images. I have never had anyone ask for larger images before. They typically just want images to put up on facebook, etc. So my questions are, A.) Where is the best place to go to learn more about Lightroom and exporting properly and B.) What is the best way to respond to this customer? In the part of the contract when it states what they will receive it just stated edited wedding images on a USB drive (as told them on the phone it would be color corrected, etc.) I never stated they would receive high res images. Thank you for the help in advance and happy holidays!
