FastRawViewer Program Window

To Choose Correctly You Need to See a Correct Preview

A JPEG's preview and a JPEG histogram can be very deceptive.

Look below; there are two previews of the same shot – one is an embedded JPEG with a JPEG histogram (left) and the other is from the RAW data with a RAW histogram (right).

Will you choose to keep this shot, looking only at the left picture?

Shot 1866 JPEG Preview

Other viewers will show just the embedded JPEG or uncontrolled conversion of a shot

FastRawViewer Shot 1866 RAW Display

FastRawViewer displays RAW as the camera captured it and as RAW converters will "see" it

For the first time ever, there is a Fast Raw Viewer that will enable you to evaluate exposure

based on RAW data and not on the brightness of some uncontrolled render or embedded JPEG.

Why Bother Shooting RAW

if Culling JPEGs?

What is the possibility of making a mistake when culling RAW shots based on the JPEG previews?

Shooting RAW, and evaluating it based on a JPEG preview is akin to making a definite conclusion about the exact shape of an object based on its shadow on a wall.

Dispelling a Myth:

Viewing RAW is Impossible

This is often used as an explanation as to why it is “only natural” that most image viewers display some render or embedded JPEGs instead of RAW, JPEG-based histogram instead of RAW histogram, and over- and underexposure indicators derived from JPEG previews.

Is it Worth it to Cull

with a RAW Converter?

Using a RAW converter as a culling tool is an extremely time consuming endeavor, not to mention other serious inconveniences, such as uncontrolled collection growth which slow down the overall process and creates constant optimization and maintenance requirements.

Suggested RAW-based Workflow

Key Benefits and Features of FastRawViewer

Ingests and Displays RAW

FastRawViewer is the only viewer to work directly with RAW

and not just with an embedded JPEG or an uncontrolled RAW conversion.

Nevertheless, if you want to look at the embedded JPEG or if you are shooting "RAW + JPEG",

with one click you can see these internal and external JPEGs together with the JPEG histograms.

Display of a RAW Shot

as the Camera Captured It

FastRawViewer RAW Display

Ingests and displays files of almost every single existing RAW format, including native out-of-camera DNG and files converted to DNG.

Display of an Embedded JPEG

(Internal Thumbnail)

FastRawViewer Embedded JPEG Display

Supports the display of embedded (internal) JPEG, that is, thumbnails which are built into RAW, and also displays the histogram for JPEGs.

Display of an External JPEG

(from the Pair RAW + JPEG)

FastRawViewer External JPEG Display

Supports the display of external JPEG from the pair RAW + JPEG; the convenience of working with the shots taken in the RAW + JPEG mode.

Very Comfortable Speed of Browsing through any Amounts of RAW Shots

Works with any file system, access any media from flash card to network server,

with no intermediate catalogues created and no disk space wasted

•  6-8 frames per second

on a modern notebook or desktop computer for files from modern digital cameras 16-36 Mpix

•  24-30 frames per second for CinemaDNG 2.5k

on a modern notebook or desktop computer (we used Blackmagic Pocket Cinema files for testing)

Culling with Confidence. Extremely Fast

Unique features for the rapid and reliable technical evaluation of RAW shots

(in composite and per channel view)

Detect the Over/Underexposed

Areas from RAW Data

FastRawViewer Over- and Underexposure Indication

OE- and UE Indication and Statistics allow for the immediate review of clipped highlights and plugged shadows based directly on RAW data.

Dynamic Range Evaluation

with a Real RAW Histogram

FastRawViewer Real RAW Histogram

The real RAW Histogram allows one to evaluate whether the dynamic range of the scene on the shot fits within the camera's dynamic range.

Check In-Focus Areas

and Noise in Shadows

FastRawViewer Focus Peaking

Focus Peaking highlights in-focus areas (Edges), and highly detailed areas or areas with high noise level or false details (Details).

Speed Up Image Processing in Adobe Lr/ACR

FastRawViewer allows one to apply adjustments, and records them as XMPs,

providing Adobe converters with a better starting point

Adjust "Exposure":

Overall Image Brightness

FastRawViewer Exposure Adjustment

Exposure Correction allows one to adjust the overall image brightness; adjustments are recorded in XMP files, so Adobe Lr/ACR will go from there.

Adjust "White Balance":

Overall Image Color

FastRawViewer White Balance Adjustment

White Balance allows one to adjust the overall image color; adjustments are recorded in XMP files, so there is no need to repeat them in Adobe Lr/ACR.

Don't Waste Time
