Not all in these photos are filter or/and UniWB.

UniWB and Magenta filter may get the best all channels exposure, than, after, I will make a conversion with more possibilities.

To get a HDR-like look I converted whit zero Contrast and zero Black. The effect is illuminate the medium-low tones.

The capture, with a critical exposure to don’t blowing but get the maximum exposure before blowing, the all channels full exposure with magenta filter and a conversion without any contrast or blacks is the keys to get that luminosity.

What do you guys use for high iso noise reduction?

Yes, Only two candles. During a energy colapse.

Exif:
# Exposure Time (1 / Shutter Speed) = 1/10 second ===> 0.1 second
# Lens F-Number / F-Stop = 0/10 ===> ƒ/0 (not true, because I usa a screw mount lens SuperTakumar 50mm f/1.4, and the aperture is f/1.4)
# Exposure Program = manual control (1)
# ISO Speed Ratings = 1600
# Original Date/Time = 2008:11:10 21:55:01
# Digitization Date/Time = 2008:11:10 21:55:01
# Exposure Bias (EV) = 0/10 ===> 0
# Metering Mode = spot (3)
# Flash = Flash did not fire, compulsory flash mode
# Focal Length = 5000/100 mm ===> 50 mm
# Colour Space = sRGB (1)

RAW (DNG), hand hold camera, PerfectRAW converter, PS after.

Thanks a lot.

Look to that article about magenta filter:
Using Magenta Filter for Shooting With a dSLR Camera Under the Daylight | LibRaw

I use a magenta filter and UniWB to get a full three channels (RGB at Bayer Matrix) exposition and avoid a tipical software WB daylight multiplication ( X 2 to Red anda 1.5 to Blue)

Thanks a lot.

I understand your questions, but I think are question that considering the mountains the principal theme, and I think the mountains aren’t the objective. The objective is a local presence sensation, a “stay in this place” sensation. And the foreground is a local presence element.

But yours questions are interesting and relevant, and I thank to your commentary.

I try ever make a exposure to the right. I think the best way to avoid noise is a good exposure.

And use the PerfecRAW converter with VNG algoritm to high ISO photos.

Exemple:

ISO 1600 with two candles:


Hand 100% detail, conversion before contrast, curves and other modifications:


Face, after curves, contrast, etc (100% crop)

Processed. I think all digital photos need be processed.

I took that photo using UniWB, and it need correct and choose a WB. And contrast, sharp and saturation boosted too.

Thanks a lot.
