Light Writing/Drawing! :)

So my next tutorial is on its way and it's all about light writing and light drawing. It's a fun thing to do but I am no pro so here's a look at what I did tonight for the tutorial.

I'm sure that over time this gets easier and you get a better judgement of space and time but for me it's just a bit of fun. I have done this in the past, again just for fun but wanted to share with you how it's done. I hope you enjoy light writing if you haven't tried it before!

The Canon Powershot Sx40 HS only allows a 15sec shutter at the lowest so there is a time restriction. I am considering using the CHDK(Canon Hack Development Kit) in the future but wanted to demo this to those who may not use the software. The software will allow a longer shutter speed I believe.

Happy light writing!

    hi
    in your canon sx40 hs tutorial step four on filters you talked about a 58 mm adapter ring which i can not find here in India. is that a 67mm to 58mm conversion ring or a 58 mm ring?
    the guy at the shop told me that 58 mm ring does not fit on the outer side of the lens barrel.so he tried to sell me a 52 mm uv filter which fits on the thread that is in the inside part of the barrel. is that safe?
    pls help

    I have read a few things about this issue. I ascertained that the "threads" in the barrel of the camera's lens are not tapped or milled threads. They are, instead, a series of concentric circles.

    I think the filter simply cut it's own paths into those circles, in effect, making its own set of threads.

    As a result, one runs the risk of either wearing out the end of the lens such that the filter no longer fits tightly, or eventually getting the filter stuck.

    I do not have my SX40 available to verify my assertions, but I plan on checking it out as soon as I have it in hand.

      You're probably right or at least close enough, the threads are definitely not well build either way. I'm gonna stick with the adapter myself!

      I did check out my SX40. To my eyes, the rings inside the front end of the lens barrel are indeed concentric. They are not helical threads. Thus, I believe an adaptor attached to the bayonet mount is required to use a threaded lens filter.

    Just saw you video unboxing if the SX70, and just like I mentioned above about the SX40, you will need an adapter for a filter.

    Also, one option, instead of a cable to transfer your shots to a computer, is to use an EyeFi card. I have a 64 GB Toshiba FlashAir W-04 in my SX40. It's great, as it transfers the pictures/videos to my Android device wirelessly as soon as they are saved to the card. It will also do so to a computer. It uses Wi-Fi to do so.

    The FlashAir acts as a WiFi access point, so, if you normally use Wi-Fi to connect your computer to the internet, instead of pointing your computer to the SSID of Wi-Fi router in your home, your used the SSID of the FlashAir. You'll need the FlashAir software on the computer.

    It's pretty convenient. I like it.
