1. 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.
2. Industry standards: Yes please.
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.
2. Compatible with HDRShop
There is already is a great collection of filter plugins by Francesco Banterle, including:
- Gaussian Motion Blur
- Absolute HDR Calibration
- Diffuse SH: spherical harmonics
- Median Cut: light source extraction
- MyFilter: custom convolution kernels
- FakeHDRI: stretch out LDR pixel values
- Physical Sky: generate procedural skies
3. 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)
What you see is what you get. Promised.Hitting OK only closes the requester, because the final image is already tone mapped in full quality during the live Preview.
4. 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.
5. High Quality 32-bit Resizing
6. 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
- Open-Source Plugin SDK
