Just a word for this brilliant accessory for Diana+/Diana F+: SUPERB. Just imagine a wonderful moment that not only you can capture but you can share it instantly.
When I used the Diana Instant Back+ the first time, I found it quite difficult to estimate the exposure time (using bulb-mode) especially in low light condition, but somehow I manage to learn it by referring to Diana F+ Exposure Chart from Indian Hill Imageworks.
What can I tell you this accessory not only produce instant photos by using your Diana+/Diana F+ but also will help you to enhance your imagination. You can play with a lot of new techniques and also you can pair it with other lenses for Diana F+ (in this case, I chose to use the Diana Instant Back+ with the Diana+ Fisheye Lens and Diana+ Superwide 38mm lens), and what I should say, this is brilliant.
The Diana Instant Back+ gives you freedom to make multi-exposure photos and long-exposure since you can control it manually.
You also can some nice and dreamy look photos instantly and make your friends feel jealous.
So what’s the point here? You should get Diana Instant Back+ since you get some new excitement using this accessory and help you to have some fun. Easy, right? Never regret to have blurry and blank images since it will give you some experience to handle this accessory.
