Qpcard is a self-adhesive multi-function
reference card for digital images shot by digital cameras or scanned from
negatives or slides (shown on the right over the model's eye). The 18% gray
field is used for gray balance and exposure adjusment. The white and black
fields are used for white-point and black-point settings. The card also has a
millimeter scale for size reference.
The size of the card is 142 x 40 mm and it is delivered in pads weighing
35grams with 15 cards in each pad. Each pad is packed in a resealable
light-proof foil package.
Winter days leave us with a shortage of daylight hours for photography but you don't have to venture far to photograph birds during this season, making them a perfect subject choice.
