LCD Display Choices And Quality Graphic Applications
Q. I am searching for a display that I can use for photo work. I am in the advanced amateur class of photographer. I work with CS3 and have been using a ViewSonic P815 (21") CRT monitor since most others had tiny screens. It has been great but is starting to fail me. I would like to switch to an LCD and I don't want to take a drop in the size of my vertical photo display. I also have a budget. I am retired and photography is mostly something I just spend money on, it doesn't make me much. I have seen and worked on the newer 24" screens, but I'd have a 32" if price wasn't an object. So, what about a display like the ViewSonic VX2835wm? It has 1920x1200 resolution and lots of controls for calibration. B&H has them on their site with all the specs ($750). I have compared the specs on all of the offered displays and there isn't much difference in them (that is not to say the performance isn't different). An alternative is the Samsung SyncMaster 275T. Same specs but $250 more (and better?). And on the deluxe side is the Samsung SyncMaster 305T, a 30" display for $1300 that has resolution of 2560x1600.
A. Over the past two or so years I have been testing and reporting
on most of the LCD displays made that are specifically manufactured to the requirements
of professional graphics and photography. None of the display models you have
suggested are specifically designated by the manufacturer to be intended for
pro graphics and photography; they are displays made for general home/office
computing. Many of my test reports are available on the Shutterbug website (www.shutterbug.com)
if you would care to read them.
For your information, the LCD displays with the same 3:4 aspect ratio height to width are the 20.1" LCDs. Many of the new models are HD format, much wider than high and even more extreme than the 2:3 aspect ratio of a 35mm camera.
Two modestly-priced displays that are intended for pro graphics and photography that have a 3:4 aspect ratio are the LG Electronics Flatron L2000C 20.1" LCD and the Samsung SyncMaster 214T 21" LCD. The Samsung display does not currently seem to be in stock anywhere, but the wider and otherwise identical Samsung SyncMaster 244T is available.
I do not recommend ViewSonic because they are not a manufacturer of LCD displays, just a marketing brand, and there is no way to easily identify the manufacturing source and what the model really is. There are really very many fewer actual manufacturers of LCDs than there are brands, and LG Electronics and Samsung are the largest, along with, of course, Sony, and Philips in Europe.
I have had very large LCDs in for evaluation, like the Apple 30" Cinema Display, but I did not find them any real advantage to photographic work, and the image detail sharpness was not as good as smaller LCD screens. Just put the smaller LCD a little closer (there is no radiation, so it's safe); I have also found the 20.1" LCD size has the same viewing area as a 21" CRT, and is the sharpest and finest detailed reproducer of photo images.
Transferring Large Photo Files Over The Internet
Q. I thought I'd return a favor. You were so terrific in answering my questions about LCDs and calibration/profiling and color workflow management that, after reading the December issue of Shutterbug and your answer to a guy about transferring large files, I want to refer you to a terrific and simple (and cheap) service to transfer files up to 2GB in size.
Try www.yousendit.com. It just flat out works. It has an incredibly simple interface, is web based, so you can access it anywhere, and is completely reliable and secure. When you upload a file, the service sends an e-mail to your intended recipient notifying them that there is a file waiting for them to download. If your upload gets interrupted, you can resume it simply by logging back into the service and picking up where you left off.
A. Thanks for writing and providing a heads-up about www.yousendit.com. For some strange reason since I received the transfer question and wrote my reply a lot of different options have popped up. I have found that you can go beyond the typical limits of e-mail attachments if you and your recipient subscribe (free) to Google's Gmail.
Flash Fill And White Balance
Q. Would it be better to use the existing light (e.g., daylight, fluorescent, etc.) as the White Balance setting when using flash as fill or bounce indoors? I have been using AWB and doing a lot of color correcting in Photoshop. My cameras are a Canon EOS 10D and Rebel.
A. First of all, the digital camera White Balance setting
should be set to match the main light source illuminating the subject. Then,
if electronic flash is used as a fill, and it differs in color temperature from
the main source you will obtain a color mismatch. This, as you have suggested,
will be difficult to correct in Photoshop.
You should use a filter over the flash to match its fill illumination color to the primary source, if it is other than daylight. (Determining how much filtration and the color composition to match fluorescent would be difficult, as fluorescent color temperature varies depending on the tubes used.) However, an even better solution is to substitute a reflector instead of flash fill and to bounce light into the shadows from the main source. This would help avoid an illumination color balance mismatch.
Canon Brand Paper Confusion
Q. Recently I purchased a box of Canon Fine Art Natural printing paper. I assumed there would be a product information and instruction sheet in the box but none was included. Both sides of this paper look and feel the same and I'm wondering if there is a "right" side, or if you can print on either side. Also, I'm using it with my Canon PIXMA iP6700D printer for sepia prints and the results are very good, but noticeably on the magenta side. Color saturation seems to be very intense.
Is there a right side to print on and how do you tell the right side from the wrong side? Are there any general guidelines for using this paper? As a long-time Shutterbug subscriber, I have always valued your evaluations and advice.
A. The paper you describe is a Canon Professional product
intended for use with their wide-format imagePROGRAF printers. This paper is
NOT one of those recommended for the Canon PIXMA iP6700D model, so very likely
the software driver for that printer does not have a profile to match the printer
and the paper you have. In the future I would suggest going to the Canon eStore
website and purchasing one of the Canon papers specifically recommended for
use with your printer.
To answer the question about the paper you have, you can print on either side as it is coated on both sides. Usually you can tell the printing side by feel or surface appearance; if it's only coated on one side the paper will curve a bit so print on the side where the edges curve toward you. This is a very high-quality 100 percent rag content paper that will handle a large ink load compared to less costly cellulose fiber matte papers. You would probably obtain more accurate color and better performance if the paper were custom profiled for use with your printer.
