Digital IR

Forgive the terrible photo, I just wanted some fresh eyes on this image.
The Sony a77 arrived today, with its 830nm converted sensor, and I love the camera as well as the conversion (LifePixel).
I've spent most of the afternoon tweaking camera settings and Lightroom sliders.
This is the last image I made, it's almost straight out of the camera. Only saturation, highlights, blacks and contrast were used here, and very minimally.
Camera was set to B&W and underexposed by 1/3 stop. Custom white balance applied in-camera.
ISO 320, f/5.6, 1/500s

Ari,

That's certainly a very strong IR effect, stronger than what my R72 filter gives.

I opened the image in Photoshop, duplicated the layer, and applied adjustment/shadows hghlights, playing with the shadow slider. There's quite a bit of shadow detail that isn't visible on the web image. That 's a good thing as the web image looks a bit under exposed.

Thanks, Peter. It's deliberately underexposed, I didn't want to lose any highlights.
I'm going to fiddle some more with both camera and LR to find a more optimal setting.

Gotchya Ari. As I said, there is a lot of shadow info in the file.

Lots of great images - love the waterfall shots Peter!

Changed some in-camera settings and went through the procedure to create a DMG profile, both of which helped.
And I also went to my usual IR testing ground, the local Bubbledome surrounded by trees.
There was sun, but much of it was through clouds, mostly overcast all day.

Looking good, Ari!

Thanks, Alan!

Your images give me an idea of what I will be getting soon with a converted Nikon D2x. It is at lifepixel right now, waiting to be converted from 720 nm to 830 nm. I wanted to try the deep B&W IR in the bright sun of South Carolina!

As Peter said, "looking good"!

Thanks, Jon.
I'll also be getting a 950nm conversion in the next few days. It was done by Isaac Szabo, I'll post a short review of that later on.
I had that one done because that's what I wanted all along, but only Isaac was willing and able to do 950nm.
My goal is to get something approximating the old Kodak HIE, which was sensitive to ~930nm and had some really beautiful softness and grain.
Here's another version of one of the above shots, trying to get an HIE look:

I know it needs more grain, but so far I haven't found a good way of making digital grain.
