  Q. Digital Infrared

Asked by Megan Forbes    (K=4617) on 4/11/2003 
My Sony F707 has an infrared setting. Not like a filter, but rather, this can be used for taking still photo's, or video clips, at night in "no-light" conditions. I have some nice footage of lions and elephants at night in a game reserve, where flashes would have upset them.

The camera does come with a warning about not using the IR in brightly lit area's as it could *potentially* damage the camera. I was wondering - have any of you used this or a similar setting in daylight? Obviously I am not planning on pointing it at the sun. Any advice? Perhaps I should just get an IR filter and use that instead of the built in setting.

Thanks for any ideas :)

I would suggest trying your camera two different ways...
1) camera set to the infrared mode with the addition of an IR filter
2)camera set to B/W mode with an IR filter
Good luck and have fun...

Thanks Tess for the advice :)

I'll see if I can get an IR filter to use with it. For some wierd reason the F707 has IR, Sepia and Solarise, but no B&W.

Megan, I also have the F717 and have been taking IR pictures in daylight. Yes you're going to need an IR filter, I have a Hoya R72. I also use a ND filter to reduce tha amount of light, I have the Sony ND filter. I have some IR pics in my port if you want to take a look at the results.





 Megan Forbes   (K=4617) - Comment Date 4/19/2003
Thanks Martin,

It was actually your stock exchange bull that inspired me to ask about this :) I see the IR setting on the camera takes in far too much light (obviously necessary for the night photography it was built for), so an IR filter is officially on my "wish list".

Hi Megan, I have the 707. Yes, you will need an IR-filter (I use a Heliopan 715) and a dark greyfilter, otherwise the pictures will be overexposed.
You might have to change between manual focus and automatic focus. Sometimes automatic seems not to work correct.
Taking IR shots in regular (color) mode is pretty hard. The pictures are very grainy and deep red. Therefore you need to have a very bright IR-filter, tripod and long time exposing.

Hi Megan,

I just saw this old post, and thought I would reply. I have an F707, and use it quite extensively to shoot IR. First, you are definately going to want an IR filter, regardless of if you are shooting in Manual Mode or Nightshot mode. I use the Hoya R72, which is fairly cheap and gives great results. You can get it online at http://www.2filter.com for a pretty good price. Next, if you are shooting in Nightshot mode, you will normally need to use at least one ND filter to avoid the scene from being overexposed. When using Nightshot mode, the camera will lock into F2.0 at 1/60. I normally use my R72 with an ND4 and an ND8 filter (3 stops total) when shooting in Nightshot mode.

I prefer to use Nightshot over manual. Manual exposures need to be at least around 2 or 3 seconds to give good results. I like the flexibility of taking handheld nightshot mode pictures.

One suggestion I have for shooting in Nightshot is to set the EV compensation to -2. This will darken the frame somewhat. I normally use Auto focus, and it seems to work pretty well.

If you are interested, you can check out my IR galleries at http://www.pbase.com/jamesl/infrared

Take care,

James

Can i Do infrared photography using my Nikon CoolPix 4500. I have not seen anything on Infrared. I am assuming if i can do panaromic stitching, which is not an option on Sony F707, and its equivalent counterpart in price/features as Canon G3, it must exist.. can anyone tell me if it is an available feature?


- thanks
