The Only Real WYSIWYG Raw Viewer

The Essential Workflow Tool for Every RAW Shooter

Is your RAW converter slow while building 1:1 previews or culling RAW files?

Use FastRawViewer - a great time-saver and an ideal RAW workflow helper.

FastRawViewer opens RAW files extremely quickly and renders them on-the-fly, instead of just displaying embedded JPEGs. It allows a photographer to see the RAW exactly as a converter will "see" it, without any delays or waiting time, guaranteeing the possibility to sort and cull RAW images lightning fast and based on the quality of the RAW itself, not JPEG previews.

FastRawViewer's RAW-based tools (unique ones such as RAW histogram, RAW statistics, Shadow Boost, Highlight Inspection, Focus Peaking, per-channel view, as well as familiar ones like Exposure Compensation, White Balance, Contrast Curves) allow one to estimate what a converter will be able to squeeze from the RAW image data and make preliminary adjustments to the RAW file, which will be read and applied by Adobe converters.

FastRawViewer provides tools for the rating, labeling and sorting photos, and filtering of any number of RAW images.

FastRawViewer supports a variety of RAW, JPEG, TIFF, and PNG formats.

FastRawViewer is very user-friendly and seamlessly integrates into any existing RAW workflow. It is extremely flexible; nearly all of its settings can be tuned and keyboard/mouse shortcuts can be changed according to individual habits and preferences.

To Choose Correctly You Need to See a Correct Preview

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

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

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

FastRawViewer azaleas RAW and Embedded JPEG View Compare
FastRawViewer High Dynamic Range Scene RAW and Embedded JPEG View Compare

Other viewers will show just the embedded JPEG or an uncontrolled conversion of a shot (left part of the picture).

Only FastRawViewer displays RAW as the camera captured it and as RAW converters will "see" it (right part of the picture).

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.

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 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

Highlight Inspection dims the shadows/midtones, and increases the contrast in the highlights in order to evaluate the details in the highlights.

Per-Channel View

Check Each Channel Separately

FastRawViewer Per-Channel View

Per-Channel View allows one to evaluate the noise level as well as over- and underexposure amount and areas for every channel separately.

Speed Up Image Processing in Adobe Lr/ACR

providing Adobe converters with a better starting point

Adjust "Exposure":

Overall Image Brightness
