I am getting ready to do a couple of different printing projects. I am going to try to make a few books documenting different years and update several of my photos around my house and office (from 5x7s up to 16x20s). In the past, I've used either Adoramapix or Mpix for my printing. I was wondering if anyone recommended other printers?

Also, I printed a number of 4x6 photos last year right before Christmas (our typical gift to grandparents are photos documenting the year for the family). In 2013, I started adding more vibrance and color saturation that I had in years past. I waited until too close to Christmas and had to print them at a local Walgreens. I noticed in the prints that the color was extremely saturated, much more than had appeared on my monitor. It is possible Walgreens added their own "color correction" to the prints, but I try to always uncheck that box. So, I was wondering if anyone knew if prints were more sensitive to adding color saturation and vibrance than monitors or if this was just an issue with that batch of prints from Walgreens?

Any other tips for printing images?

Thanks,
Brant
