<p>Are you giving them 300 dpi from the digital camera? For a 5x7 that would be the largest size – 2048 x 1536 pixels on a 3.2 megapixel camera.</p>
<p>Also, you have to use the SuperFine setting – minimum JPEG compression – if you want to rival film. The medium JPEG is noticeably lossy on some textures. The standard “max compression” setting is very noticeably lossy, even on a computer screen. </p>
<p>Neither of these is a standard setting because the file sizes are quite large: about 1.5 meg per photo. The pro stuff lets you save uncompressed TIF files, which is the optimum. But, a 4x5 is a 5 meg file.</p>
<p>No question that film is better when doing traditional custom-print developing. But, two cameras with comparable optics, being developed on the same machine one digital and the other digital scans of film negatives, should not look different at those small sizes. I’ve used both for four-color brochure work with the film stuff coming from 4x5 large format transparencies on a drum scanner and, frankly, the digitally shot stuff is more consistent and predictable. If it’s going to end up as pixels, it might as well start out as pixels.</p>
<p>One thing to keep in mind is that the scanner in the one-hour foto lab machine is doing sharpening, white point, black point, and gamma adjustments on your negs automatically. I’m not sure that is being done on your digital files unless you do it at home or on their little kiosk.</p>
