Yes, you are right, pure HDR needs at least 3 different exposures, I've seen some works of people using as much as 9 exposures. What I do is the following: Convert original file (photo) to TIF, and create different exposures of it as TIF also, using Camera Raw. But it's not always necesary to create different exposures, because some pictures are so good they don't need extra exposures, just run them thru your HDR tonemapping program, settings, and you are good to go. This is called Faux HDR or Pseudo HDR. After that, I re-process the HDR result in Photoshop, using various features of the program. Brightness and contrast, Denoising the HDR result etc.

Hope this helps...

Re: B&W image conversions

Hi nebulaoperator,
You didn't mention what software you have, or I missed it, but if you have Capture One, try the B&W profiles from JFI Labs - http://www.jfilabs.com/. The film set for $19.95 is the one I would recommend. These are profiles are made specifically to be used in Capture One, used in place of the standard profile for your camera. You choose the film you would like to emulate and then do the adjustments to the raw file from there. Best tonal transitions I've seen. There are plugin programs that also let you choose a specific film type, but in my opinion are not nearly as good as the JFI profiles.

Re: B&W image conversions

Learn about "luminosity masks" which can be applied to BW as well as color images. Especially useful for contrast adjustments in BW.

Great website: http://goodlight.us/writing/luminosi...tymasks-1.html

The actions are worth every dime to simplify the process.

Re: B&W image conversions

Hi Danny,

Thank you for luminosity suggestion. Great link. I used luminosity mask . It worked better for shadows
. Though I followed all steps in that tutorial it did not work well on midtones. Originally photo was way overexposed. I was hoping I would have greater seperation highlights, midtones, shadows. I don't know what to think at the moment.

Re: B&W image conversions

One of my favourite methods of B&W conversion involves creating 2 Hue & Saturation layers above the background. The top Hue/Sat layer is set to color blend mode and desaturated completely. The bottom Hue/Sat layer allows you to adjust the hue to emulate any colored filter.
