Comment on Avoid QuickBooks and Intuit’s Extortion by JJ

I wasn’t aware that buying a 2008 version of quickbooks was illegal, can’t be registered or used. I can’t afford to buy new version. I want to learn quickbooks but can’t use it now. After 30 days it will not work

Comment on Aligning Images for HDR by Doug Kaye

Hi, Jeff. The lower-right image in the first group of four shows the results of Merge to HDR Pro in Photoshop, so you’re right: the alignment is good. My concern would be the next step: the merging of the aligned images into the 32-bit HDR EXR file. I think that’s the most critical step in the entire HDR process. Tonemapping the EXR back to a 16-bit LDR image is something you can control in most apps, but I have a sense that the creation of the EXR is where PS is weak. Having said that, I have not tested it, but I should. Unfortunately, this test is a lot more subjective that testing for alignment, but I’ll give it a try. Thanks for posting this suggestion.

I think I might have an easier way for you.

Select all of your source images and Edit in… > Merge to HDR Pro in Photoshop. (Stay with me here…we will only be using PS for alignment and not for tone-mapping)

This will load all the layers, align them, and combine them into a 32-bit color space PRIOR to tone mapping.

Leave the mode in 32 bits and click OK on the HDR dialogue.

This will leave you with a 32 bit file open in Photoshop.

Save as OpenEXR format and then open the 32 bit EXR file in Photomatix for tone-mapping.

Wouldn’t this accomplish the same thing and with far less steps, extra files, etc? Or would there be data loss with this method. Most curious to know.
