Picturenaut 3.2 Description:
Picturenaut 3.2 was developed to be an image editor focused on HDR generation from a series of bracketed exposures, tonemapping, and HDR editing.

Nowadays there are several applications for all these tasks coming from the photographic side of HDR imaging, which all concentrate on giving beginners an easy start by compromising control for advanced users.

Features:

Create HDRIs from multiple exposures:
- Automatic image alignment
- Exposure correction
- Color balancing
- Ghost removal
- RAW support
- Noise level compensation
- Full control over camera curve

- The HDR generation runs asynchronous from the user interface, that means less coffee breaks and a healthier lifestyle for you. Scripting ninjas can use the fully featured commandline version MKHDRI to weave it into an automated workflow.

Industry standards:
- It reads EXIF metadata and ICC profiles from the source images. Aperture, shutter speed and EV offset can also be edited manually, so you can easily compensate for ND filters and missing/false EXIF data. The ICC profiles are used to optionally derive a reliable standard camera curve.

- You can also change the bit depth of any single LDR, and Picturenaut converts it properly into a pseudo-HDRI using a standard gamma curve, or any curve you saved from an ICC profile or derived from a set of calibration images.

Compatible with HDRShop:
- Plugins originally written for HDRShop integrate seamlessly into Picturenaut as well. They simply show up in the "Filters" drop-down menu. They run here better than ever, because their console output is routed to the display and Picturenaut doesn't time out on them like HDRShop does.

Tonemapping on the fast lane:
- One local and three global tone mapping operators are built in, all with mind blowing speed due to multicore-CPU support -
- Adaptive Logarithmic (ala Drago)
- Photoreceptor Physiology (ala Reinhard)
- Bilateral (Local TMO)
- Exposure (simple snapshot)

- Every change of the settings updates 100% live on the preview image, even while you are dragging the slider. Watching the histogram squash and stretch in realtime is the ultimate learning experience for figuring out what all these sliders do. As soon as you let a slider go, the current settings are applied to the full size image as well - which usually takes just about some milliseconds.

User-defined Gamma Encoding:
- Unique is Picturenaut's ability to reuse the camera curve for the Gamma adjustment of a tone mapped LDR result. That way you can preserve the specific look of your camera, or simulate that of another one by applying a previously derived curve as post-adjustment.

High Quality 32-bit Resizing:
- Only Picturenaut offers 7 different interpolation options for resizing HDRs, with precise control over sharpness parameters. Of course, they work on LDRs as well...

Rock solid Architecture:
- Aside from all the whizz-bang, Picturenaut sports -
- Undo and redo
- Zoom and pan
- Display gamma and exposure
- LDR formats: TIFF, JPEG, TGA, RAW
- HDR formats: TIFF float, OpenEXR, PFM, Radiance RGBE
- UNICODE support
- SSE/SSE2 support
