Infrared, anybody?
Jun 4, 2019 11:03:14 #
Lovely pictures. I notice in the second picture some issues I'm also working with. The first is the clipping in the clouds, which actually gets worse in processing. I may try to force high dynamic range and possibly underexpose a stop or two in an effort to retain cloud detail.
Next week, I think, the X-E2 will go off to Kolari to be converted from 720 to 590. They assure me it will still be possible to get an in-camera custom white balance, though I've heard that this is not possible. We'll see. If I can't, besides being very angry I'll have to try to shoot IR in RAW, though there's a dearth of recipes for IR white balance in the tools available in Linux. My experiments so far have been embarrassing, abject failures. But if 590 white balancce proves to be no problem, it ought to be a whole other world, as I think you'll find with your new filter.

I have my a-77 with 590 conversion, if you want me to test any specific w/b settings and post, let me know.

Thanks very much. What I'm hoping for is the ability to set WB in-camera, as I can with 720nm. But while you're here . . .
Is there any special trick to setting white balance with the camera? Do you take it from foliage, as with the 720, or something else?
Tips are extremely welcome. Make that begged for!

Unfortunately I have no idea other than at 2,700k we the foliage including evergreens is all white but the sky is brown.
With cloudy wb foilage is less white and sky is more red. I’m running errands right now but will post a couple shots later.

describe,
I was planning on doing an auto white balance in PP as has been suggested but now I am wondering if it will work with my 590nm. I will see.
Thanks,

Just try doing a custom WB on green grass for comparison. That works best for me.

IR works expecially well if you can get up high on a really nice day.
Love it!

One cool thing, I think, about 720 is that it's relatively easy to get a kind of impressionistic subtlety of colors -- nothing like a Miami Beach Fiji bar, which is the gaudy direction IR is sometimes taken. To wit:

I presume my color IR work is the kind you feel is "gaudy". But the great thing about color IR is it's False Color, so it can be anything you like, even if you like bright saturated colors better than subtle color.

That's not something that applies particularly to infrared -- any digital picture can be made into any colors you want:

Of course it can. But visible light photography starts out with "real" colors, and the realists and SOOC crowd expects the color to be "real". With IR photography there is never that expectation.

Not so. The colors are expected to behave in a fairly predictable fashion. Otherwise, it's not different in any important way from what I did to poor Dennis Kucinich.

The 590nm X-E2 body (this one a Life Pixel conversion) arrived today and like magic the sun came out. So I made a quick picture. Only post was auto white balance and channel swap.

Looks like that my red 25A filter is very closed to 590nm if not exactly! I may not need to obtain another one!
Look at this taken with the 25A with auto balance/channel swap.
