Light Impressions was for years a very reputable and well-run company in Rochester NY, specializing in darkroom, framing/matting and similar supplies. I lived close enough that I bought directly from their retail storefront for years, since I could actually see and handle the merchandise.
When the business was sold I feared the worst, and apparently the mail order experience has not been good.
On the other hand, Light Impressions' founder and some of the original retail staff reconstituted at the same location as Lumiere Photo, emphasizing direct retail sales, custom mounting/framing and service bureau-type large format inkjet printing. They now also do mail order stuff through their website. The manager Bob Alles is a genuinely great guy, and they've always provided excellent service. They mount my large panoramics for me and do a consistently fine job. They just moved about 8 blocks into a much larger industrial space, and appear to be expanding the range of services they offer.
