Taking Infrared Photos

Johnny|lucidcomposure · 12 Jan 2008 at 14:44

I rememeber it been a tuffy to do on Nikon cameras. There are two ways of doing it I believe. Took me ages to set my mates up.

well you can set it to use a reference photo for the white balance, or you can just do it on the fly so to speak.

i've always done it on the fly, and just pointed the camera at some grass - told it to use that, and then it says "good" on the screen if it can use it.

I set it using a reference photo, but that didn't seem to work. I will try doing a measure approach next time. Perhaps it was because of the lack of real green with this time of year, but I would have expected some difference

I was a bit of a numpty today though, as I left my camera on ISO 3200, and wondered why I was only needing shutter speeds of less than 30secs at F/10 ish

Will have to give it a go again tommorow, depending on the weather!

I havent had a chance to experiemt again yet, busy all weekend

So if I shoot in raw, and change the WB later, I don't need to have set the WB in camera?

correct.

Just seems odd that two of us both Nikon users, have exactly the same issue. I don't mind however changing the white balance after. Maybe I will have another look later this week!

Hi again

I need some advice on histograms and checking if I am over/under exposing.

Here is my white balance shot with histogram.

Here is an image using that WB.

I struggle to get anything good from these in ps

Any tips?

look at your photo. Under treatment there is a dropper tool. Thats your custom White Balance seletion tool that can be used in that image. Pick it up and click it on a part of the grass and the red will vamoooss!

Assuming your photos are RAWs

Helium_Junkie · 20 Jan 2008 at 15:36

Fstop, I've been doing that but it still only gives very very poor results

However, I went out today and used the "measure" mode... the pictures looked a lot more like what I expected on the preview! Will let y'all know shortly

expect lightroom to ruin them unless you convert to 16bit tiff using something like bibble first (am assuming nikon here btw)

Helium_Junkie · 20 Jan 2008 at 17:21

I am a D80 user Gex

So you assume correctly.
I have processed the more recent batch straight into Photoshop rather than Lightroom, will post some up after dinner

Thanks everyone for your advice and input.
