Navigation
View an image directory as thumbnail images.
Click on a thumbnail to view or edit the full-size image.

RAW file conversion
The first image is the jpeg produced by the camera.
The 2nd image is the raw file from the camera, converted to tiff-16.
The 3rd image is the edited tiff file saved as a jpeg file.
The dark areas were lightened and color was slightly increased.

Flatten Brightness Distribution
An easy way to improve detail in areas that lack contrast.
Uses a single sliding control with live feedback.
Sometimes works miracles and sometimes not very effective. 

Edit within an area outlined with the mouse.
Little Mermaid was backlighted. The fix was to outline her and flatten her brightness distribution.

An area may also be selected by clicking on it - a contiguous area with matching color
(within an adjustable range) is selected. This can be refined to select a smaller or larger area,
or accumulate incrementally with mouse clicks and drags. The tea box areas were mostly
selected with one click each, and then brightened all at once.

The dark bush area was selected with multiple clicks and then brightened.
The middle image shows the final selected area. This was done in a few seconds.

Cut and paste objects from one image into another.

Brightness and Color
The color of the right bird was intensified without changing the rest of the image.

Lighten dark areas and/or darken bright areas.
Edit a brightness curve while watching the live output image.

Playing with color: intensity, saturation and depth.

Brightness Ramp 
Fix vignetting and other problems with brightness uniformity.
This image was also enhanced afterwards (color, noise, tone-mapping).

Red Eyes
Remove the red-eye effect from flash photos.
Here only half the red-eyes have been fixed.

Sharpen
Comparison of different sharpening methods on a badly blurred image.

Noise Reduction
Reduce noise in photos made under low-light conditions.

Rotate

Unbend
Sometimes panorama images need to be straightened.
Adjust while watching a live output image.

Unbend can also be used to fix perspective problems.

Warp Area
Select an image area, pull in different directions using the mouse (rubber image).

Pixel Edit
Use for retouching. Pick a color from the image or a color wheel.
Variable brush size and transparency allow gradual change without edge effects.

HDR - High Dynamic Range Imaging
The lower image is a composite of the upper two. Brighter areas were taken mostly from the darker image, and darker areas mostly from the brighter image. Color and contrast were also adjusted. Image alignment is automatic (10-30 secs. per image) and hand-held photos work fine.

HDR photo of the Ingolstadt city center. Two photos about 1/2 second and 2 EVs apart. This made the shadows soft instead of nearly black. The people were all moving, but there is almost no "ghosting". Why? The people were all in shade, and therefore only the brighter photo contributed to their images. The only exception is a cyclist in the lower right, who moved from shade into sunlight between the two photos.

HDR photo of an arm of the Grand Canyon. Two photos, two EVs apart.

HDR using 5 images from http://www.debevec.org/Research/HDR/.
The input images are 2 EVs apart (overall brightness ratio 256:1).
The left image is the HDR output, before manual adjustments.
The right image was adjusted with tone mapping.

HDR of St. Louis at night. The input images came from the Wikipedia article
http://en.wikipedia.org/wiki/High_dynamic_range_imaging
(the HDR specialist program Qtpfsgui is presented there).
Here the fotoxx HDR output was tone-mapped in three phases.

HDF - High Depth of Field
Combine two photos of the same subject, one with a near focus and one with a far focus. In one photo only near objects are sharp, in the other only far objects. In the combined image both near and far objects are sharp. This function is very sensitive to changes in camera position or aiming point - these cause parallax errors and changes in image scale that cannot be fixed with simple translation and rotation. These are still compensated as much as possible. If you are careful not to move the camera too much, you can get good results. The samples here were hand-held.

This HDF required about 2 minutes of processing time and another 10 minutes of manual work to choose which input image to use for each area in the output image.

Panorama
Combine multiple images to make wide images. Rough alignment is done with the mouse and fine alignment is automatic. This image was also color enhanced and unbent. All samples here are from hand-held photos.

Acropolis closeup, a challenging panorama. A case where turning the camera with low lateral movement was important for good image alignment. The guy in the striped shirt moved up the steps between the two photos, so he is seen twice in the panorama. The joint can be seen behind his upper image, since no blending was done. The automatic brightness and color matching worked perfectly, which is not always the case.

Tags
Add tags (keywords), dates, and "star" ratings to images. Search images using these criteria and (wildcard) file names. Matching images are shown in a navigation window of thumbnails. Tags are stored inside the image (EXIF). A fast-search index is initially built and then updated as image additions and revisions are made. Search speed is thousands of images per second.

Art Effects
Convert a photo into a simulated drawing, painting, or embossing. These take a few seconds to a few minutes, depending on how fussy you are with the GUI controls.
