1. Launch Photomatix
2. Generate the HDR Image.Windows users click Generate HDR Image in the floating Workflow Shortcuts window.A dialog box appears that asks that you select the source images.
3. Load the images.Find the images you want to work with, select them, and click OK to get them loaded into Photomatix
4.Select the options you want to use.After the images load,you see the Options dialog box,You have to make several decisions here. The options are:
> Align source images.This is almost always a good choice, even if you use a tripod. It is also wise to keep the image uncropped, as you can always crop later in the process.This is not necessary if you are using brackets created from single raw exposure, as they are already aligned.This is almost always
> Reduce chromatic aberrations.Select this option if you notice purple fringing or other evidence of chromatic aberrations. These areas most often appear along the borders between contrasting areas.
> Reduce noise.This is optional. You can use your processing application’s noisededuction features or try this one. There are very good third-party noise reduction filters such as Noiseware which you can purchase and use instead.
> Attempt to reduce ghosting artifacts.Ghosting occurs when leaves move or if someone is walking around while you take your photos. Photomatix can try and reduce this but the results are not miraculous. Ideally, you want to keep in-frame movements at a minimum on-scene. This is not necessary if you are using brackets created from single raw exposure, as there will be no movement between frames.
> Tone curve.Leave this option as is if your photos have a color profile associated with them. This should be the case with TIFFs and JPEGs, whether they are taken directly out of most cameras or processed through a raw editor. For raw images, this option should be grayed out, because raw images do not have tone curves.
5. Generate the HDR.Click Generate HDR and wait for the result to appear on-screen. Depending on the bit depth of the originals (JPEG versus raw and TIFF), the number of brackets, their size in megapixels, the extra options you’ve chosen, and, of course, the speed of your computer, you could be waiting a moment or two or much longer. You will eventually see your HDR image. It will look horrible. Don’t worry — the HDR file you’re looking at has 32 bits of information per channel and your display cannot handle this range.
6.Save the HDR file.Choose File ➪ Save As to save the HDR as an .hdr file now. You can return to Photomatix in the future and load this HDR file to start a new tone mapping session. This saves time because you won’t have to re-generate the HDR and is very helpful if you want to quickly run through multiple tone mapping sessions to test out different settings and save the resulting files.
Congratulations. You’ve created an HDR image that is ready to be tone mapped. That’s where the real magic of HDR happens.
