I can sum up my impressions of the FLD-A046 Cokin filter in one sentence. The blacks improve but at the expense of the whites.
Here are some test details:
* Plan A *
My plan was to take before and after shots with a canon G1 digital camera. I also was going to take a shot of my 27" toshiba for additional comparison. I had set up an account at www.photopoint.com
to share the photos.
I should start by saying that I am a complete novice at photography so it is very possible that my results are due to user error. But after 3 hours of fiddling with the camera, I found the color accuracy so poor, I have opted to tell my tale in words rather than present false visual data. No matter what I did, the G1 tended toward blue.
* Plan B *
My test was run with the VE test patterns and montage of images movie. I started with the settings of black level and contrast. No change was required to brightness or contrast, but the black level was noticeably blacker.
At the same time the top white box in the contrast pattern tended toward gray. This was more noticeable when I switched to the SMPTE color bar pattern.
I then went through the montage of images 3 times. On every image I would manually raise the filter and then lower it. The dark scenes were improved in my opinion. But the light scenes looked hazy like every day was overcast.
As far as color correction goes, there really wasn't any color shift. Bright colors went duller in light scenes and dark colors went darker in dark scenes due to the added "haze".
It comes down to personal preference whether one will like the FLD filter tweak or not. I wasn't thrilled with the compromise I had to make with my whites. But I'm not picky about my blacks anyway. It's all about relativity to me and when I watch a movie the blacks look black.
It has me wondering about my incoming grayhawk, though. Same compromise? We'll see.
I'm going to try a different digital camera. If it is any better, I'll post photos.
ps. Those who have been trying to get ahold of me, my e-mail address has changed. I am now a northpoint refugee, riding the 36k highway and using hotmail until my new DSL line is installed and my e-mail server is back on line.
