moiré and false color test



Next moiré and false color test. Honestly, cost me a lot of energy to do the test. Initially considered simply shooting those rules Founder lines objects can appearPhotography Equipment moiré beginning facing window screens only took a few, but no moiré and false color. Went on to do the test with a cloth, nylon cloth, winter Photography Accessoriesjacket try, but somehow, the phenomenon of moiré and false color are difficult to appear in front of these materials above, the last in the lining of a jacket artificial cotton barely take a pseudo color photos.
In accordance with my
camera tripodown ideas, because everyone shooting objects and different shooting conditions, bad generalize judge moiré and false color camera phenomenon Camera Accessoriesseverity for general photography, too high a resolution may Camera Equipment
be unnecessary. But for me, if you want no moiré pseudo-color and high resolution at low resolution to choose between, I will choose high resolution.
Combination of tests with different lenses
Earlier chat with several Pentax engineers have filed:

First to introduce this lens. The lens was listed in 1958, is Pentax's first return to long-range wide-angle lens, and is also the first in the history of

Lighting Studio of the imaginary phenomenon has begun to emerge, looks a bit unnatural. Since the outset, stressed imaging resolution sacrificed focus imaging effect of slightly reducing the sharpness should be improved.
