    Interesting filter use

    I ordered another CPL filter the other day. Because the three filter set with case was only $2.00 more, I ordered that one. I received the CPL, a UV and an FL-D (fluorescent.)

    While reading the interesting comments about using the filters on the website, I noticed that the FL-D was recommended for sunset and sunrise. hmmmmmm

    So, having never thought of using a fluorescent filter for daylight shots I thought I'd try it out. The two shots following were not shot to showcase my photographic ability nor for art, but strictly to see what effect the filter would have on a sunset. Straight from the camera, no PP at all.

    With the filter:

    A few seconds later, without the filter:

    D40 f:5.6 1/125th

    I just thought this might interest some of you.

    What a dramtic effect that had, I think the top one is far better, it gives it a real warm glow.

    But hey, what do i know, im just a novice

    Hi Pops,

    I notice from EXIF there is a slightly different focal length and also the framing isn't the same, plus the filter will have blocked some wavelengths of light more than others, so the pattern/multi-segment auto exposure will have come up with a different answer, but you seem to have compensated and got the same ss, f stop and iso on both, I can't help feeling that is contributing to the effect.

    OK that's what you wanted to show, but I suspect stopping down the non filtered shot might have had some similar effects and an alternate WB done the rest.

    The counter argument is that if you hadn't compensated with framing and angle of view to get same ss/f-stop/iso and just let the meter take the shot, it might not have looked so different.

    Or am I being daft?

    I'm NOT agunna touch that one.

    If I had set the tripod up and gone to full manual, I could have done a better job of true comparison. However, the sunset would have been gone by that time. I just wanted to see if there would be a noticable effect, so set the D40 on P, installed the filter and shot 4 rounds, removed the filter and shot 4 more. The "with" is the last shot of the series and the "without" is the first shot of that series. (I think I remember that properly.)

    I was not expecting the dramitic difference. I'll do some more work in the future to get a more scientific evaluation of the technique.

    Ah, but then I wouldn't have to think about it.

    Re: Interesting filter use

    Being an old film guy, I still have a selection of filters from those days which I do use occasionally when I shoot digitally. However, I usually prefer to shoot without filters (CPL, ND, and very occasionally a GND being the exception) because virtually any other effect can be duplicated in post processing.

    Re: Interesting filter use

    Wouldn't you get the same effect by changing the White Balance on the camera to fluorescent?

    Re: Interesting filter use

    I have seen sunset taken with the camera set to Flourescent and it is not the same. That is why I wanted to try it. The results I got were enough different that I thought I'd bring it to your attention.
