I think the IR-pictures are a little bit
underexposed.
Colors:
without filter (WB: cloudy):
with RG715 (WB Auto):
with RG715 (WB manual):
comment: Typical purple
shift of Sony's 5 MP 1/1,8" sensor. With manual white balance good
colors. The IR-effect is not very strong, but visible.
Picture Quality:
The following pictures are 1:1 crops of the original images. Saved in
Photoshop with quality level '7'.
without IR-Filter:
with Heliopan RG715 (WB manual):
The crops are taken near the border
of the image. The details are great for IR, much better than many other 5
MP digicams.
After post processing you will get some noise, especially in the sky.
Noise is not very strong, perfect conditions for Neat Image. The IXUS
500 can produce high-quality IR-pictures.
