Dynamic Photo HDR

Creating HDR 19

Because we are working with only a 8-bit (or 14bit for RAW) dynamic range the result will have much

more noise, clipping and banding than image created from multiple sources. It will have also higher

contrast because there are not enough data to smooth the transitions.

* The RAW files have 14 bit dynamic range, because the CCD of a digital camera is 14 bit, even that

RAW file is actually a 16 bit file. Some companies claim 16bit or 32bit processing, but still their imager

is 14 bit.

3.4 Align

If the images were taken without tripod we will need to align them. The Align dialog will automatically

try to align the images as a first thing, but a further alignment may be necessary.

This dialog offers many advanced features to perfectly align any type of image.

Images

One of the images from the set is automatically chosen as a Base image. This is always the Image

that has the best exposure (closest to 0 EV). Other images will be aligned against the Base image.

That means if we have 3 Images as source, we will see two lines in the image list BASE + Image A

and BASE + Image B, where the BASE will be 0EV and image A and B will be under and over -

exposed. If we have only two images as or source then we will see only one line.
