The Unbearable Lightness of Mystic "Exposure" Triangle

We should begin by saying that the point of all of this is not just to criticize one of the most repeated photographic myths out there – that's just a tool, because an incorrect understanding of the way that exposure and ISO work, as well as their roles during the shooting process, leads to a falloff in the quality of shots that photographers get.

So our goal is to show how, by rejecting this myth, you (the now-enlightened user) will be able to more fully utilize the capabilities that your camera has, as well as to improve the quality of your photographs.

Red Flowers Photography: Now It is Easy to See the Real Picture

Some time ago, we published a couple of articles ("Red Flowers Photography: Real Problems or Deceptive Previews?" and "Forcing a Raw Converter to Render Tones Accurately") demonstrating a multi-step procedure that allows one to prevent Adobe raw converters from showing false highlight clipping.

Now, with the settings that allow one to cancel the baseline exposure compensation and support Highly Linear Mode that are being introduced in FastRawViewer 1.5.2, this process has become much more automated.

With the addition of support for Pentax, SonyPixelShift2DNG is now PixelShift2DNG

With Beta 0.9.8, we add support for Pentax, subsequently changing the name of the application to PixelShift2DNG.

In order to streamline the workflow with the raw shots taken in the Pixel Shift Multi Shooting mode offered by the Pentax K1(-II)/K3-II and Sony A7R-III cameras, and provide a way to use popular RAW converters for processing these shots, we’ve developed the PixelShift2DNG application, which now converts both Sony and Pentax shots taken in Pixel Shift mode to DNG.

The resulting DNG files can later be processed in applications like Adobe Lightroom / Camera Raw, CaptureOne, Iridient Developer, Luminar, and others.

ISO is Seldom just a Digital Gain

RawDigger. Raw histogram. Digital ISO 25600

Some say, "exactly like dragging exposure slider in Lightroom, ISO ... is just digital gain". With a few exceptions, this is less than a half-truth.

Though it is often the case that at higher ISO settings digital "gain" is applied (or a converter, using a metadata tag, is instructed to apply it), analog gain still acts first, before "digital gain" (the better word would be "multiplication", not gain, as in electronics "gain" most often pertains to analog domain).

The giveaway for multiplication is deep and regular gaps in the raw histogram that become wider with each increase of ISO setting.

A Curious Case of ISO Bracketing with Fujifilm X-series

A few days ago, a FastRawViewer user turned to us with a question:

"I took a series of photos with ISO bracketing, but FastRawViewer shows them all in the same way on the main window, even though the JPEG previews are different. I think you have a bug!"

In answering him, we suggested several reasons as to why this is happening, among which was the option that "It's possible that your camera doesn't even do anything when the ISO is changed".

The user sent us the files, and the result was...exactly that; the automatic change of the ISO setting while bracketing didn't affect the RAW data at all.
