Hi,
having almost decided to buy the EI-2000 (or the HP stamped
"version", which is priced now here around 500$), and playing with
it a little, I have some more questions about it.
1) hotshoe flash synch - in which exposure modes does it work? in
manual, sure, but also in Av mode? I often use autoflash on K2 or
similar older cameras in Av mode with exposure compensation to get
both flash and ambient in balance - is it possible with EI2000?
2) what is the iso setting at which there is least noise? Or is
there any difference between 25 and 50 and 100? Is the 400 setting
usable at all?
3) shutter lag - HP 912 sheet says 0.35s lag (it's suprising they
even mention it, most producers want to hide the fact that their
cameras have large shutter lag). Compared to film SLR, e.g. K2 or
LX or SFXn - is that much? How much has e.g. K2 or
SFXn? Is the lag lessened by prefocusing and locking the focus?
4) in B&W mode, is it simple using something akin to Luminance
channel or desaturating in Photoshop, OR does it sample each pixel
directly to B&W?
Sampling directly each pixel regardless of the pixel-colour-filter
would give about 1.5-2x more image detail than in colour! For
superiour B&W photography...
please, somebody try this: Tripod mount your Ei-2000 and make a)
picture in colour b) same pic in B&W mode. Than, desaturate the
first picture in Pshop, and compare it to second, B&W picture. If
they are same (un)sharp, it's the worse approach. If the second,
B&W pic is sharper, it means NO interpolation was used and thus ALL
THE PIXELS of the CCD are used directly, without interpolation.
(this interpolation is often evident in colour pics as colour
shadowing of high-contrast boundaries. simple way to remove it is
change to LAB mode in photoshop and blur with Median or Gauss both
the A and B colour channels -about 2-5 pixel radius median works
well-, leaving the Luminance channel not blurred. Then, combine
channels and look at the result, most colour artifacts should be
gone. This greatly improves pics from ANY digital camera! Only
drawback that sometimes small areas of different colour disappear
or get desaturated)
Thanks!
Good light,
Frantisek Vlcek
