Interesting macro photography done with Nikon DSLR camera:

Microsculpture is a unique visual experience. A 10mm insect is shown as a 3 meter print, revealing minute detail and allowing the viewer to take in the structure of the insect in its entirety. The beautifully lit, high magnification portraiture of Levon Biss captures the microscopic form of these animals in striking high-resolution detail.

    People took that film festival more seriously that I expected, 550 short films! and some of them very creative. This alone should change Nikon strategy about video.

    • Patrick O’Connor

      I rarely shoot video so excuse my ignorance but what are they doing wrong? Perhaps they’re not using the newest, coolest tech. but from a pragmatic POV, what isn’t possible given their current offerings?

      • Eric Calabros

        – no aperture control in live view for entry level DX bodies.
        – lack of video friendly AF lenses. They released new AF-P version of 18-55, but its only one lens, and not available yet.
        – lack of on-sensor PDAF that eliminate or at least decrease the haunting issue.
        – no log profile. You dont get maximum DR of your sensor in video, while its best of the world in “still”. they recently add ADL for video in D500, which lift the shadows and let you underexpose to save the highlight, but Its only available in 1080p.
        – no focus peaking or any focus aid except %100 zoom, and that zoom is not among the best implementations.
        – 3 min limit because of outdated FAT filesystem.
        – h.264 is a consumer codec

          …which only serves to underscore my ignorance regarding video! 🙂

    I’ve got the B&W UV Pro. I personally can’t confirm it works as I don’t have a totally control environment. Perhaps I can shine it on some moldy bread and see if it does anything.

    What I can say though are the following:

    1. It packs extremely nice. A lot better than I expected.
    2. Safety features are great
    3. It doesn’t feel cheap in hand

    I haven’t tried to shine the UV ray directly to the sensor. I really don’t think it is a good idea. If you shine it when the mirror is down then there is no problem. Just make sure you don’t look through the view finder while you’re doing it.

    Anyone in NR want to donate a camera and let me try to shine it directly to the sensor? 😉

    • Elky Asno

      The amount of UV light produced by that tiny toy can’t be anywhere near the UV coming from the sun. And people take pictures in broad daylight all the time, even locking the mirror up to blow out the dust quickly while in direct sunlight!

      I doubt there would be any danger at all in shining that thing direct into the sensor.

      • PabloNY

        So if you get more UV light from daylight, this product does nothing for you?
        I don’t understand why I would need one.

        • I’m guessing that the device works by shining UV light into the lens when it’s in storage, which is when the fungus would ordinarily be growing.

          • PabloNY

            That’s what I thought until I saw it only takes 2 minutes.

          • Espen4u

            Hmm. Don’t forget to remove the UV-filter then. Sounds a bit like snakeoil to me. A good fresh cobalt-60 source would also do the trick, by the way 😉

            • Jim Huang

              From what I know, these product are quite popular in Asia, which can be quite humid and we don’t have a lot of space. Most of us don’t have a garden to put our lenses outside for hours. We don’t have a lot of room inside neither. Anyways, I’ll do some experiments to see if the product actually works.

            • spocky77

              Some of the older nikon lenses are slightly radioactive (Google it). It would be interesting to see if they ever had a fungus problem.

      • Piooof

        Wrong. The glass elements of the lens filter out most of the UV light. If you want to do UV imaging you need specialized quartz lenses like the UV-Nikkor 105 mm.
        So in ordinary operation both the rear lens and the sensor are shielded from that 300 nm UV.

        The same goes for the light coming through windows: don’t expect to tan behind a window, and to kill fungi on your lenses by removing the dust cap at home.

        And no, I wouldn’t shine 300 nm UV on a sensor, it may well bleach the Bayer array. As far as I understand, the idea here is to stop fungi developing on the focusing screen.

        • Jim Huang

          I’m not a scientists, but from I know normal glass only blocks UVB rays and UVA ray can go much deeper. I guess this is what it is using.

          • Piooof

            Their UV-LED emits 300 nm UVB. I doubt it’ll go very deep. Hopefully it offers some way of stopping fungi on the most exposed elements, if enough light reaches the inside of the rear/front lens.

            • Jim Huang

              According to the menu, it uses UVC, which has shorter wave length. I am not sure how much penetration it gives as most of it don’t it (if any) even reach to earth’s surface.
              It guess it helps that you can shine it from both ends.

            • Piooof

              You’re right; I read too quickly the blurb about light wavelength which is *under* 300 nm. It also says UVC so if it is close to 200 nm the glass will filter it out less (but I doubt it is < 250 nm though). Anyway if you leave it there for days you'll finally get some effect, at least on the visible elements. But it won't kill the spores that sit inside your lens patiently waiting for humidity and temperature to rise again to higher levels. I'd rather invest in a dry box if I were shooting under tropical conditions.

  • David Weinehall

    Those macro photos of insects?! Woooooh!

    • Patrick O’Connor

      Now I have to figure out a way to finance a trip to England to see the exhibit. 🙂

      • doge

        I hope that becomes a traveling exhibit.

    • whisky

      while macro-stacking illustrates a perspective people wouldn’t normally see, what caught my eye most about those photos was the author’s use of light.

  • CERO

    The Pro Mold thing seems to be only for Canon.
    Also, why the hell is so overpriced on amazon? its more than double the price of the ebay one.

    • New Yoko

      because I bought the last Nikon version for $144 on ebay. i shoot in green house conservatory and summer in japan which can be tropically humid. i just received it. nicely packaged and well made. will write up a review soon after testing

      • CERO

        I still have no idea what your comment has to do with mine.

  • Captain Megaton

    I keep my lenses in a drybox. Recharge the silica gel 2-3 times a year, though if you are less of a cheapskate than I am you can get one with a plug-in dessicator that never needs to be recharged.

    An UV LED fungus killer seems like an awfully convoluted solution to a problem which already has a simple answer.

    Maybe if you had a lens with fungus in it already that you wanted killed?

    My only concern is the UV light damages the glue and composites holding the lens elements together. It seems unlikely, but you’d not know until its too late.

    Made by P.T. Barnum

  • outkasted

    OMG! Bermuda Photographers will love this as many are plagued with fungus problems often spending yearly costs to send equipment offshore for cleaning etc…

  • I got the Sigma 150-600 Contemporary for $600 from craigslist last week. Pristine condition, boxed w/everything plus he threw in the docking station, cheap UV filter, and a Wimberley plate. He paid the same $989 current sale price in December. I’m so stoked. Too bad it’s been cloudy here for a week and no sunshine forecasted until Sunday. :/
