Everytime I take a picture with my r72 the image is red no matter if i set my white balance to the green grass or not! i tried to follow these insturctions http://home.comcast.net/~vicpinto/IRPostProcessTutorial-1.htm but they are worthless because i can not even get close to his colors someone please help! thanks
sounds like the custom white balance hasn't worked to me..... What camera do you have?........ are they all red in the camera preview screen?
If I hear anyone say that digital IR is as good as or better than real IR, I'm going to run around the city breaking every DSLR I see. Interesting conversation though....carry on.
um ok..... digital IR can be as good as as film (if you mean film by saying 'real IR')..... you best get smashing Hmmm.... they should be blueish/brown in the preview screen..... try retaking the white balence..... it took a few attempts for me to get a good one..... Make sure its taken from a sunny area of grass and that the camera excepts it as a custom WB.
ok, This is a long winded response, be prepared...... Here is the deal. 1 Film IR is better than digital IR because it does capture more detail and it is more sensitive to the IR spectrum. However, to the layperson (not a photographer), a digital image and a film image held up next to each other, they will not be able to see the difference without it being pointed out to them. End of that argument. The shots with digital camera will come out red out of the camera. Best thing to do is shoot in raw and apply a software custom white balance. That is MY OPINION...don't argue with it, it is not a statement of fact, it is the best method I have found. Other ways are to shoot a custom white balance and use that for all your shots, however do to the movement of the sun, refraction of the atomsphere and about a billion other factors the white balance will need to be reshot throughout a day of shooting as the color of the light from the sun will change dramatically throughout the day. I use a software white balance that I set in my camera raw software during processing, YMMV, Use your own best method. once your white balance is set in raw software then your image will look more like IR. I personally don't typically shoot IR in jpg mode, (ok, I have never shot IR in jpg mode) because I don't know of a way to change the white balance and therefore the shot will be red because the r72 filter I use filters everything above the red spectrum and most of visible red as well. Just realized you stated you had a D70s. Shoot in RAW, you will be much happier with the results. They will be red coming out of the camera. You have to process them on your computer before they will look like film IR. The D50 and the D70s both use the exact same sensor. with Digital IR you have the option of processing the photo to B&W IR or what is refferred to as False Colour IR. I personally prefer false colour, as does a friend of mine whose gallery is here. Cheers,
OK its still not working Iv'e tried to use custom green wb's like 20 times and they still all come out blood red, any other suggestions?
What program do you use to adjust the white balance in RAW photos? I have Raw Essentials (I think that's the name... I could be off though) and it gives an eyedropper to adjust the white balance. I'm guessing it figures the white balance by me clicking on 50% grey but I'm totally guessing. Could you give some more info on how to figure out what the white balance should be when editing in software? Thanks.
yes, in Rawshooter Essentials..... you select the custom white balance tool (the wb eyedropper).... and click on any part of green grass or tree area. Thats basically it..... you should now have a blue/brown image which you should export as a tiff...... Once in ps..... you can then choose to adjust the levels/contrast as it is..... or if you want to make the sky blue again, (often known as IR false colour) you can swap the colour channels...... here's a link which can help you do this..... http://home.comcast.net/~vicpinto/IRPostProcessTutorial-1.htm photyo, if you cant get the custom WB to work, just shoot with auto WB..... then use the steps i'v discribed above in your RAW converter software..... but you cant use Photoshops own RAW converter because it has problems with the temperature gauge....... try a free RAW converter or Nikons own converter.
I prefer setting the WB with raw software, as mentioned above. If all else fails, convert to black and white.
