I want to get some prints done but initially at a modest size of 16x12 inches. The lab I used last time I printed (way before the Merrill) require JPGs at 402 dpi. So, I need to save TIFFs from SPP, then export from LR as a JPEG to the required size. I assume that all I have to do is go to the Export menu and in Image Sizing, set the resolution, then tick Resize to fit and set the long edge to 16in, having already cropped the image to the appropriate ratio. This effectively up-samples the file and it doesn't look great at 100% but I guess no need to worry about that?
Also, any hints on output sharpening? If I have left sharpening at the default in SPP, what should I set in the export menu in LR? I think I have used 'sharpen for glossy paper/standard' in the past for prints from other cameras.
Just wondering if anyone else is using LR to create JPEGs for labs to print and if they can share experiences on how to create the export file.
