IR Experts need alil help
« on: October 19, 2007, 04:35:04 PM »
hi to all, I need alil help from IR people here coz i tried my filter for the very 1st time...im not really fond of sceneries n such but theres something about IR that fascinates me. Anyway the other day while waiting i tried it out. Its late afternoon (430) on cloudy day so there isnt so much sun,but for the heck of it i still tried it. What i did is focus on something then set it to MF then installed the filter used a tripod anyway. I also tried playing with WB. I did 6 shots in total with diff ISO, shutter speed etc. Please dont mind the composition since i didnt bother frame it right coz i wanna see the IR effect 1st. These images are straight from cam just resized it,gurus please tell me what i did wrong...i believe i didnt achieve the IR look i need to know the technics of basic things to do. I know the time of day is really wrong but how do u guys achieve those effects? my shots are red or orangegy which is wacked :-\ TIA guys

not an expert.

nagkaroon ng ir effect if that is the question.  :)

exposure lang ang nakita ko na me kulang. watch for the histogram and check that the peak is  in the 2/3 position (more or less) and the valley doesn't hit the right wall.

hope that helped.

i searched the internet...  here is what i got...

-----------------------------

1. First, test your digicam. point your TV(or any Infrared) remote controller at your digicam, press the remote(any button), view through your LCD preview or snap a image if you use DSLR. If you can see your remote's bulb lighted(usually in light pink), then your digicam is able to do IR shoot.

2. Buy a Hoya R72 filter that fits your camera lens filter thread, screw on in front of your camera's lens, or in some case, your digicam's adaptor tube.

3. Wait for a sunny day, go to a park or anywhere that have trees(its everywhere lah) with your camera and tripod. Before you start, do a custom white balance for your digicam WITH your R72 filter on. Either on a bright patch of greens or the blue sky, results will differ slightly.

4. After you do your custom WB, set your digicam to custom WB.

5. Attach your camera to your tripod, camera's setting is as per your preference. Shoot to your preferred composition.

6. Go home to your computer after the shoot, load your images to your computer. Open images in Photoshop. Do a auto contrast if your images are underexposed due to the filter. Select Channel Mixer, select Red Channel in Channel Mixer, slide your Red percentage to 0% and Blue to 100%. Now select Blue Channel in Channel Mixer, slide your Blue percentage to 0% and Red to 100%. The basic process is DONE!!!

7.Of course you can still further tweak your colours to your preference.

Just a reminder, IR Photography is an effect, you should always remember to compose your image and have a subject or theme to make your image interesting. DON'T be blinded by the IR effect!

Custom White Balance Setting for D70s

----------------------------

Setting CWB for Nikon D70
Procedure is the same for D50 and D70s

1. Camera set to "P" mode. Fit filter (R72) onto lens. Zoom to max, on the kit lens or any lens you may use. This ensures colour reference for CWB will fill up the frame.

2. Press WB button at back of camera and turn command dial to change WB to "PRE". View this on the top LCD.

3. Press and hold WB button at back of camera. You will notice "PRE" flashing at top LCD.

4. Point camera at a bright sunlit patch of grass, press shutter as in taking a shot. Make sure you fill the whole view frame with the patch of grass.

5. If CWB is recorded in the camera's buffer, "GOOD" will show at the top LCD.

6. You're done. CWB is set for IR shooting.

There is a timer in the camera when "PRE" stops flashing in step 3. Repeat the step again by pressing and holding the WB button to get "PRE" flashing again.

So everytime you want to shoot IR, just change your WB to PRE. Once set the CWB can be used indefinitely, unless you find the colors strange and want to reset it.

again from the internet...

-------------------------------------


CWB for Canon EOS 300D, this one is easy
Screw on the IR filter(R72 or your preference) onto your lens before starting.

1. Make sure your White Balance is on Auto (AWB)

2. Point at some brightly lit green leaves or grass or the blue sky.

3. Take a picture!

4. Select MENU.

5. In Menu, under the "CAMERA" Icon, select "CUSTOM WB".

6. In "CUSTOM WB", Select that image of green leaves/grass or blue sky you
just took. Press "SET"

7. Now select your White Balance Selection and select the ICON for "CUSTOM WHITE BALANCE" which is that "rectangle floating above 2 triangle" icon.

follow the instructions of vernes. he is a master of IR!

usually the problems arise in two areas:
1. creating hte custom white balance
2. getting the right explosure.

no, you will not get a monochrome shot as you were expecting. the colors depend on the custom white balance you create and the intensity of the IR in the subjects you took. the best time to do this is on a sunny day and from 10 am to 2 pm. your time of shooting will not create good IR shots, IMHO.
