Solution To Photoshop Elements 3.0 & Acrobat Problem
So, David, you took a royal scalding from Mr. James Reis (May 2005 issue) because he believed he could print a PDF from Adobe Photoshop Elements 3.0 after reading your review of the program. He was pretty upset, it seemed, that after spending $100 for Elements he would now have to spend another $250 for Adobe Acrobat 7.0. Sounded like he wanted you to refund his $100! Well, since you have been so helpful in my transition from film to digital, I am going to help you redeem yourself. Anyone not having Acrobat can go to www.pdf995.com and download PDF995. There is a free version, and a $9.95 version. But for just $19.95 you can download the full function version. You might pass this on to Mr. Reis. If he hasn't already shelled out the dough for Acrobat 7.0 you just saved him $230. Seems he should split the savings with you, don't you think? Keep up the great articles.

Thanks so much for offering this solution lead. It looks like it will work for those who need the capability that are PC Windows users.

Some Choices Between Printers Are Functional Choices, Not Which Is Better
Q. You wrote two excellent articles in Shutterbug about ink jet printers--one about the Epson Stylus Photo R800 in the August 2004 issue and one about the Canon i9900 Photo Printer in the October 2004 issue.
I am an advanced amateur photographer who is just getting ready to get involved in digital darkroom work and I was intrigued by your articles, but I am having trouble trying to decide which of these printers would be best for me. Do you have any suggestions as to how I should decide?
via Internet

A. Thank you for the kind remarks about my articles. I can understand having some difficulties choosing between the printers I reported on because both do a superb job of reproducing photographic images in prints. So a choice must really be made on factors other than print quality. One factor might be whether you would be satisfied with prints that are letter size--or would you require making larger prints, as the maximum width of the Epson R800 is 8.5" (letter size) and the width of the Canon i9900 is 13". Another factor is print life. If you want your prints to remain true to color for generations, then the pigment ink Epson utilizes in the R800 provides considerably longer print life than the dye inks that are used by the Canon i9900.
Other than these two differences of size and print longevity the printers should both provide satisfying performance and utility. I hope I have been able to help your decision making.

Avoid Losing Image Information Data
Q. I'm using Photoshop CS on a Windows XP operating system. When a raw image file that has been created in 16-bit color, saved in a TIFF file format, and then converted to 8-bit color is saved/closed and then reopened/converted back to 16 bit, does it gain back the 8-bit color information, or is that permanently lost? The only reason for converting to 8 bit is to save file space, but if it results in any permanent loss I will leave it at 16 bit.

A. No, I am afraid once a 48-bit image file is reduced to 24-bit RGB color all of the data that would not fit in 24-bit color space is discarded and cannot be recovered. It is always a good idea if you have originals in 48-bit color depth to archive them as such on permanent media like a CD so you always have access to the full body of information for future use. These days memory space, especially CDs, is really cheap, even the archival gold/gold CD-R discs. So what savings are you really talking about?
