Photography has come a long way in 70-plus years and, apparently, so has advertising. While flipping through the Popular Photography archive, we couldn't help but be mesmerized by some of the old advertisements that once graced our pages. Some of them are interesting and some of them are downright comical by today's standards. But, ultimately, they provide a fun look back at the progression of the photographic equipment we love so much. One day, we'll laugh when we see an old advertisement for a DSLR with 23 measly megapixels. Then we'll head off to shoot some images with the gigapixel cameras that are implanted directly into our eyeballs. But, until then, use this gallery of old ads to take a trip down photography's memory lane.
