I think the IR-pictures are a little bit underexposed.

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.
