Being able to set a custom white balance, or at least being able to set white balance to "cloudy" or "sunny" or other options is a real advantage. If you can understand white balance, and how to set it properly for the lighting conditions - it will take you a long way to beautiful photos of any subject. On a point and shoot type (not a more expensive digital SLR) I also like having "scene" settings like "beach" - that works well for me for taking photos of daylilies in bright sun, especially yellows.
Different cameras "see" flower colors differently. While one camera may take the blue of a delphinium perfectly - it won't even see the "purple" of a daylily at all correct.
Cameras and daylilies are very frustrating. When I bought my Nikon Coolpix, they were not nearly as inexpensive as they are now. I think it was $700. I bought it at a regular camera store. I went to a florist, and bought a mixed bouquet of flowers. They didn't have daylilies - this was a couple months before daylily season. The camera store people took the cameras out in the parking lot in "real sunlight" and we took photos of the flowers laying in their hedges, then took them inside an looked at them on the computers. I bought the one that had the most natural looking colors over the broadest range. Over the next couple months, I was taking all kinds of photos - and I loved the photos it took. Then daylilies started blooming. That thing takes the worst red and purple daylily photos! I could not even fix them in Photoshop. I ended up going back and buying the Canon Digital Rebel -- and now I wish I had waited a little longer and spent just a few more hundred dollars on a Nikon D70. The Canon has an overall yellow/orange cast on most shots of daylilies. Not on other images, just daylilies, and all colors. Easy enough to take out in Photoshop, but I'd sure prefer not to have to fuss with all my images!
However, between the Nikon point and shoot, and the Canon SLR, I can get shots of most everything I want. Still not perfect daylily shots, but I'm not convinced there is a perfect camera for daylilies. The Nikon D70 is the closest I have seen, and I don't think they are selling them anymore.
Dave really is a genius, and he sure is trying to please everyone.
