Qpcard 101 Review

qpcard 101 Life Pixel Infrared Conversion

B&H Photo - Video - Pro Audio

Introduction


Qpcard is first and foremost a gray balancing calibration paper, You can also use it to make sure you don't blow highlights/shadows. The Qpcard is made out of thin plastic, and painted with accurate white, black and gray. It has a self adhesive strip on the back, so you can stick it to walls etc. It comes in packages of 3, for the 101.

Specifications


Size. 142mm x 40mm

Price: $16.95USD

Positives


  • Easy to use. Although they should have provided information about how you can keep the highlights and shadows from not clipping, when you use the card.

Drawbacks


  • Expensive. I wouldn't have minded the price if the quality of the product was better.
  • Build. The Qpcard scratch easily, all of my samples shows paint dabs on them. Making them less accurate.

Verdict


A very easy to use product, If the product had a better build quality this product would be a winner. That said, my cards are still usable, but for the price paid you want something that last longer and function 100%. On my 3 cards there seem to be the gray part which is the worst. I don't know if the cards I got was a bad sample or not. That said this product is definitely ok, as you can see in the sample pictures below.
