This was my first time using a service to scan some older negatives from back when I was shooting film. I have been a professional photographer for over 30 years and all my negatives are in very good condition. My project had 18 medium format negatives and two 4x5 negatives to be scanned.. They were requested to be scanned at their highest resolution, 4000 dpi.. The files I received are quite low in resolution. In addition, all the images have been severely cropped. Only about 50-60% of each negative appears in the image. At 4000 dpi I would figure these files should be much larger. One of the 4x5 negatives files is also 8MB and one is 21MB. Why the difference? None of the files I received are usable. They are low resolution and severely cropped. I have tried contacting customer service a number of times by both email and phone but have only received one call back. The agent said she would look into my problem and get back to me the next day. That was 4 days ago. I have left another message on their customer support line but no answer. I have spent over $240 for 20 unusable files and zero customer support.
