For personal storage, I prefer external hard-drives. CDs and DVDs are better for passing the files along to others, simply due to price and portability. The way we do it, we have two 2-T external hard-drives; once each month, I transfer the past months accumulation of files onto the second hard-drive. When it is evident that these two drives will soon be full, we will get another two. Any image files we wish to pass along to someone else get copied onto a DVD. As for scanning slides and negatives, I have been looking at the purpose-made slide/negative scanning devices described on Amazon; my understanding is they are actually a digital camera with slide and negative holders made into the "lens" tube, complete with SD memory card; reviews claim this type of scanner is preferable to a flat-bed for scanning slides and negatives.  |

I want to clarify my previous statement concerning scanner "DPI" (dots per inch) and image viewing "PPI" (pixels per inch) When I stated that they were the same thing, my meaning was for the purposes being discussed of scanning images to digital. I can only speak for my poor man's scanner. When I select "scan" and "as a photographic image", the only resolution option it gives me is a choice of x-many DPI (dots per inch). However, whatever DPI I select, when I get the image loaded in the Elements "editor", it recognizes the scanner's DPI as the exact same number of PPI; so, whatever number of DPI I select at the scanner, results in the exact same number of PPI in Elements. In my own experience, scanning at 600 DPI is about ideal; scanning at a higher number doesn't seem to add any more quality and only results in a bigger file. I can, however, see the difference in loss of image quality with each subsequent step less than 600 DPI. What this all means is that, if I scan say a 5x7 photo at 300 DPI, I can print a 5x7 of equal quality; if I scan that same 5x7 photo at 600 DPI, I can get away with making a 10x14 print. These are just my own experiences and someone who actually knows what they are doing and with better equipment will do things differently. I hope this is helpful; thanks for reading. |
