    Out of boredom, I decided to put 3 B/W filters and stack them onto my 19-35mm just for fun :D

    I was pretty pleased with the results, but I had to use lightroom to drop the RED levels down to about -20 because I used a Red and Yellow-Orange filter. LR over blew the red to about 70-ish. Not sure.

    My NEX has a higher DR than my Canon so I thought how much DR can I get from stacking 3 BW (Red, Y/O, GRN) I wasn't really trying to be scientific for this test. I do wish there was more clouds in the sky though.

    First Photo post here btw :D

    Two things, Synomis192: 1) Why did you shoot all these at f/22? That's well beyond the point where diffraction starts to degrade your image. You'll get much better results if you keep it at f/8 or less. And 2) you'll generally get more responses here if you post images directly into the thread, rather than make us click on links. It's very easy with Flickr, just click on the little box/arrow at the bottom of your photo, and then copy and paste the code that appears when you click on "Grab the HTML/BBCode."

    Edit: D'oh! Never mind. I see that you did that. :rolleyes:

    Great Questions:
    1). I wanted to test this at it's limits, lowest ISO, slowest shutter speed, and smallest aperture. If I were to do this again (which I will) , I'd do a lot of different combos. This was taken about 15mins before posting haha.
    2). I fixed that already haha, thanks for letting me know though. Took me a while to figure it out. :D

    Care to explain about diffraction and why shooting at such small apertures causes that?

    I usually shoot landscapes at f/8-f/11 but again, I shot this to try to push the equipment.

    Well, I could try. But this explains it much better than I could: ;)

    Well, I took 2 quick shots at f/8, work better for you WoodWorks? haha both were handheld though.

    EDIT: Same LR PP (B/W Filter, -20 Red, Sharpness +100)

    ISO 800 - 1/20 @ f/8 - 19mm

    Can't say that I see any difference. :p

    But they're different sizes, so...

    I usually post at either 800 or 1024 px on the long edge, depending.
