The LB color intensifier creates a more saturated color environment. The LB warming polarizer is two filters in one...a warming filter and a polarizer. The LB combo is the LB warming polarizer and the color intensifier all in one (three in one).

Ken and rh89 are correct...you can simulate the results of these three filters using post production techniques. I've found that especially true with the color intensifiers...they are easy to duplicate by just increasing your saturation a bit.

That being said, it is also best to do as much as you can in front of the lens versus doing it on the computer. It will give you better image quality in the long run. While programs such as Photoshop and Lightroom (I love them to death!) are awesome and are getting better every day, there is still a bit better quality image achieved from a filter...such as better color rendition with less chance of degradation. There is always the chance of degrading your image when you post-process...even if it is only slightly. By using a filter, you are modifying the original light, not the captured pixels after-the-fact, thus giving you a better chance of high quality results.

I don't own any of the filters you mentioned, though as you know, I own quite a few Singh Ray filters. But I do know colleagues who do and they love them and swear by them. There is a lot here that boils down to personal taste and work flow. I personally prefer to stay as close to natural as I can and use post-production simply to sharpen, crop, and adjust slight saturation. I feel this increases my chances of getting more keepers and sellers.
