Re: HDR

HDR means High Dynamic Range, heres an exact meaning


the most widely used software is Photomatix Pro, theres many others like Artizen
or this one wich is very good just like the paid ones but free, so I would start with this one Qtpfsgui - Home

Re: HDR

If you have CS3, it seems to produce results that are comparable with Photomatix.

Re: HDR

I would have a go if I was you. That picture of the Atlantic Coast Express would have been ideal for HRD if you couldl have set up a tripod when you took it.

Re: HDR

mind, you can do an HDR with a single RAW file just by raw processing at 3 different EV levels.

It's not ideal but it does work.

That said, it's a pain in the ass with CS2 (dunno about CS3) as it looks at the EXIF and sees that each of the three "different" images are at the same shutter speed and won't let you continue. you have to save each of the three EV levels to TIFF then mess with the EXIF info manually then reload them in CS2.

Photomatix doesn't give a monkeys.

What I do is open the same image 3 times in PS. Raw process the EV at my three levels then save each as a TIFF. I then open the 3 TIFFs in Photomatix, generate and HDR then save it as a .hdr (radiance file) which I then open in CS2 to perform the tone mapping (I can't stand the Photomatix tone mapping - except for skies).

Re: HDR

Remember, if you only use one RAW file you are still limited to the information within that single Raw and limited in dynamic range. Using Photomatix will not be able to produce a genuine HDR image but it may be useful for medium dynamic range photographs (7 - 11 stops) where you may otherwise have to save and combine more than one Raw conversion. In such cases Photomatix would be much quicker. For subjects with a dynamic range of 12 stops or more, it is beyond the range of a single Raw file so only multiple exposures can deal with this.

My advice is to measure or estimate the dynamic range when you take the photograph and take multiple exposures where necessary or if there is doubt.

Dave
