Minolta 2300 @ISO85 (rounded to ISO80)
Filter: Heliopan RG715
without IR Filter
time: around 14:30 o clock MET
date: 03 June
weather: nearly blue sky
It's very sensitive to
IR-Light. So you can use it without tripod most times. It is comfortable to hold, if you use the viewfinder, you get sharp shots down to
around 1/8 sec (because you have always a 38 mm lens).
A real problem is the LCD, it's much too dark. You couldn't use it
outdoors, even in the shade you see nearly nothing. So you compose
with the viewfinder and your eye something, you can't see. In a
way, this makes great fun.
The control layout of the
camera is the worst, I ever used.
without filter (WB: auto):
with RG715 (WB, Auto):
The camera uses the tungsten
white balance, because of the red cast.
image is much to red. You can correct this, it's getting a
little bit noisy, for that you have Neat Image.
Another problem is the vignetting. You see it even at the
with-out-filter-picture in the upper edges. In IR-pictures it gets worse.
After a little bit Photoshop (Auto Levels) the
colors look nice, noise is low. The wood
effect is very strong.
But the pictures have always one problem. Even if you print them to 9
cm photos, do not expect much of detail. A C-2020 captures more!
Be fair, the camera costs only around 30 €, you need only a very small
filter (30 mm are enough), and its very sensitive. For the price it's a
really great fun.
If you are going to capture real art (with big print sizes), you better
look for a good IR-camera with 4 MP or more.
The sharpness is good in the middle of the image. The edges are a bit
soft, but for the price it's OK.
What is the right
With the RG715 it gets to much red. The red channel is sometimes near
overexposure, the blue and green channel were dark. But I think the
RG715 does a good job. The Hoya R720 can be a bit better.
If possible buy a Olympus
C-2020. It's more expensive, but the control layout is much better. It
captures also more details, and you get better color-IRs. ;)
