Extract middle 24bit image, then whatever as bottom, top

Submitted by maxotics on

Forums: 

Hi, I'm doing a video about s-log for YouTube and would like to show how a RAW image can be thought of as 3 sets of image data. The center 8bits, say (like a JPG) and the the bottom 2 bits and top 2 bits? Is there a way to extract the pseudo images from RawDigger? That is, a JPG that is the first 2 bits of data, a JPG that is the center 8bits of data, and a JPG and that is the top 2bits. Each file would be 8bits of course, so they could be viewed. Hope you know what I mean. Thanks! Max

RD 1.2.18 x64 abends with GFX files

Submitted by JimKasson on

Forums: 

Pretty repeatable. Load GFX raw file, make selection, convert selection to sample, save sample, click append, hit control-rt-arrow to get next file. If that works, append data, click contl-rt-arrow, and get "Program has stopped" working window. Sometimes fails on first press of cntrl-rt-arrow.

Works with ARW files.

Win 10 Pro x64, 2x Xeon 12 core, 256 GB RAM.

Any ideas? Thanks.

White point on X-Trans sensors

Submitted by mkulagin on

Добрый день!
Я пытаюсь выяснить точку насыщения для своих камер (Fujifilm X-100T и X-T1).
Результат получается на мой взгляд странный -- насыщение в разных областях кадра приходится на разные значения (см. приложенные файлы).

Вопрос: что это, особенность моих экземпляров камер или вообще X-Trans сенсоров?

how is conversion to RGB done?

Submitted by rawdiguser on

Forums: 

Hi, thanks for RawDigger, I was pleased to find it as a way to view all photosites in a raw file. Two questions:

1) When Display is set to 'RGB render', I gather white balancing and exposure may be adjusted, as controlled by Preferences. When building the RGB values for a pixel, is any information other than the 4 RGBG values used to build the RGB value? I ask because dcraw documentation talks about interpolation, etc, suggesting that it (and thus maybe s/w based on it) use values from neighbouring photosites as well as just the four 'local' values.

How to see actual Bayer Data at pixel level

Submitted by leopp on

Forums: 

I am doing design work on a hardware ISP.

I want to see Bayer data as I would expect from the sensor:

First Row: BGBGBGBGBG
Second Row: GRGRGRGRGR

and so forth.

Can I go down to the pixel level and look at individual pixels? If output a TIFF file for each color what is put in the pixel location for other colors? In other words if I output a TIFF with Blue only what is the value output for Green and Red pixels?

Finally can I see the pixels that are black from the sensor - Usually the first few columns or last few columns of the image?

Nit: Show date-stamp on Download page for Change Log. Also more info about what changed might be helpful.

On the Download page:
http://www.rawdigger.com/download

I think it would be helpful to have some kind of date-stamp for when a particular version was released. The could be part of the "Change Log".

In the Change Log, some items are pretty obvious, but others are obscure. Perhaps there could be a reference/link to a Feature Request or Bug Report or some kind of discussion on what the impact of the change has.

getting it into photoshop the way it looks in rawdigger

Submitted by Frank Burkert on

Forums: 

I am using raw photo processor and fast raw viewer and I tried to make the pictures looking the same as in raw digger. The decrease of saturation was a way to bring it closer but it is not perfect. Is there a simple solution for bringing the pics into photoshop the way they look in raw digger or is this completely not possible because of the architecture of this all?

Saturation point seems to vary depending on the subject/lighting

Hi

I've calculated the headroom of my highlights based on the tutorial on your website.

I'm getting inconsistent results though i.e. sometimes I'm clipping the highlights.

Several times I have done the headroom test and have measured my saturation point to be 13,284 (Green channel after the black point has been subtracted).

On a canon 5D3 I have done a few tests which measure around 3.5 - 3.7 EV headroom so I am using metering for + 3 1/3.
