Inadvertent Oversize Web Graphics look GREAT on a Retina Display
My favorite lighting systems are those from Lupine Lighting systems, sold here in the USA by GretnaBikes.com.
See my extensive reviews of flashlights, head lamps and bike lights.
The GretnaBikes.com has long been a bandwidth-wasting site by using much too large graphics that are drawn at a small size on screen. BUT now with the MacBook Pro Retina display, all of the product images look GREAT, because they provided plenty of resolution on the MacBook Pro with Retina display.
The image below of the Lupine Betty II lamphead is drawn so that it fully utilizes the Retina display resolution.
