Description
Well at least it's the first shot uploaded here from my new camera. A modded Olympus VR-370, I've been waiting nearly a month for this camera (the modding took time by the associated people to those that sold me this ). Only contrast was adjusted for the image. It really does view things this way by default. No filtering used really.This shot as taken maybe an 1/8 of a mile from where I live.

Hi Erin - Thanks for this. Let me go over a couple of things, so I can suggest ways to develop your work. First, you are working with a full spectrum (FS) camera. So, both IR and Visible (Vis) light are reaching the sensors. The RGB sensors do not have the same response to IR light as they do to Vis light, in particular the red sensors are more sensitive to IR light, and so straight images like this have a red/orange/magenta cast. In this case, that actually works very well for the image because there is a lovely differentiation between different type of foliage - see the leaves on the left against those in the centre and the range of hues in the grass. Suppose, however, you did not want that cast. What you would do is create your own custom white balance, and use that, normally, in camera. I don't know the firmware associated with Olympus cameras, but it will be similar to Canon and Nikon and so on. What you do is take a shot of a grey card, or, if you do not have a standard grey card use aluminium foil (matte side), or at a pinch green grass. The image should be then a more or less uniform (red/orange) colour cast. Now, set that image as your white balance in camera - there will be instructions on how to do this. You also need to set the white balance control to "Custom" and you're ready to roll! Images will no longer have the colour cast. If you wish to shoot images with the cast, then turn your WB control back to "Auto". Without the cast your FS images will acquire a soft pastel colour look to them. Have a go and let me know how you get on.
If you like, we could develop this into a working on-going tutorial which we could feature in the Group.
Cheers

Nice advice!
Ok, this is my first Olympus camera, and I hope it's white balance can be manually set. It does appear to be more sophisticated than my Canon Elph 130, and that can have it's white balance changed that way. ( Which I know is standard for making this sort of adjustment. ) Although using gray or green for making the adjustment is new to me. With normal cameras I'm used to using a flat white ( meaning no shine on the surface ) material for this.
Yeah, that's a nice idea, but I don't know when I'll get the opportunity for a shooting session again. ( Hopefully soon *fingers crossed* )

OK - sounds good. The use of grey is because the colour response of cameras is set to mid-tone grey. Grass green happens to be very close to that in tone, as does most concrete and aluminium foil. Setting against "white" is not so good for accurate colours.
I look forward to the results of the next shoot.
