Whether in the studio or out on location, I have found that I can alway trust my Hoodman memory cards to to perform properly 100% of the time. When shooting Merge to HDR or stitching panoramic images in the field, I would be in trouble if one of the exposures in a series is bad. Shooting tethered in the studio allows me to save a version on the cards as backup, while  letting the client view the incoming images on the computer screen. The firewire RAW card readers transfer images to the computer very quickly to save time at the end of a shooting session. I rely on my equipment to perform when needed and my Hoodman products can alway be counted on.
