Hello, I've run some test shots through a number of different printing services (matte prints only), and I've been largely appalled by the poor quality from Shutterfly and WalMart in comparison to London Drugs, despite claims to the contrary. I sent full-res photos to all print services, and LD came out crystal clear with good contrast and good colours (albeit very slightly warm and red-heavy), while the others came out somewhat washed out and blurry (I imagine the lack of contrast comes from slightly more matte paper). The obvious answer is "use LD", but the prints are *more than twice the price*. LD has gotten ridiculous with pricing at $0.55 per print *if you print over 50 photos*. That doesn't sound like much, but a batch of 100 costs $55+ vs Shutterfly's $29 and similar. I called Shutterfly and had the stereotypical 2025 lobotomized customer service conversation where they want to know where I lived 10 years ago and what my mother's maiden name is, and then proceed to not know what is already on their website. A few questions: \-Are the poor results potentially due to downsampling? Are there resolutions that provide better results? The Shutterfly site doesn't mention downsampling at certain resolutions and seem to recommend "best quality available" although saying that you "don't need anything bigger than 1024x768 for 4x6" (not true from a quality perspective). \-Is Black's better? I could always reorder for testing purposes but I'm tired of waiting on shipping, and am hoping to be more informed before trying more prints. Shooting on an A7Rii and editing in Lightroom. Thanks!
