AT LAST! GREAT PHOTOGRAPHIC LIGHTING BOOK IS NEWLY REVISED



LIGHT: SCIENCE AND MAGIC is one of the very best books (some would say it is THE best book) on photographic lighting. If you intend to be seriously involved in studio photography, this book should be on your required reading list.


A lot of photographer's have been waiting for the time when a revised edition would be available. That time has come. The third edition will be out in early April and you can pre-order your copy at Amazon.com from the link below. The best news is that you can pre-order the third edition for about $7.25 less than the second edition currently sells for.


How good is this book? Just read all of these posts at Photo.net.

MONITOR CALIBRATION SOFTWARE


"Why don't my prints look like the photos on my monitor?"


Unlike film, digital photos have no color. They exist only as a series of numbers on hard drives, CDs, DVDs, and other storage media. A variety of devices such as monitors and printers convert those numbers into colors for display on a screen or dyes and pigments on a print. The problem is that five different devices can convert the same numbers into five different colors.


I've looked at my web site photos on enough monitors to be aware of how varied the displays are. A specific red hue can show up as several different kinds of reds, not to mention orange, burgundy, purple and other colors. Monitors are getting better but they are far from being consistent.


Part of the solution is monitor calibration. With a properly calibrated monitor, a high quality printer, and the right "profiles" for your printer, photos on your monitor and prints from your printer should be a much closer match. (Printer profiles is a whole other topic.) With a calibrated monitor, the prints you get when you send you files to a professional printer should also be a closer match.


There are monitor calibration packages out there that cost upwards of $1,000. They are overkill for the average user, not too mention hugely expensive when a package at a fraction of the cost will give you very good results.


One of the best, reasonably priced monitor calibration packages is the "Eye-One Display 2" package from GretagMacbeth who merged with X-Rite. It is highly recommended by Tim Grey, one of the photography tech wizards at Microsoft who used to be George Lepp's technical guru. I've written about Tim before. George Lepp is a columnist for Outdoor Photograper.


The Eye-One Display 2 package, which includes a colorimeter and software, lists for $250 but you can purchase it for as little as $199 from a variety of reliable discount sources like Amazon.com.

REVIEW: CANON EF 70-200mm f/4L IS USM LENS




The new Canon EF 70-200 mm f/4L IS lens


The new Canon EF 70-200 mm f/4L IS USM lens is now available. This is a great lens!


The current issue of Popular Photography (March 2007, page 70) has a review. Popular Photography describes this lens as "Optically excellent" and "superbly constructed". The "Subjective Quality Factor" numbers look very good (see the chart below). At 200mm, and an 11x14 inch print, every aperture is rated A+ or A. At 200mm and a 16x20 inch print, 3 apertures (f5.6, f8, and f11) are rated A and 3 more apertures (f4, f16, and f22) are rate B+. This is remarkably good. You can read all the details in the magazine article.


UPDATE: You can now read Popular Photography's review online.


Popular Photography (March 2007, pp. 68-70) tested the Image Stabilization (IS) feature and found that IS consistently gives a 3.5 stop gain over the ability to hand hold the lens without IS. A photographer who could normally hand hold a 200mm lens and only get a sharp photo at 1/250 second and faster, can hand hold this lens at around 1/30 or even 1/20 second and still get a sharp shot with IS turned on. Given the sharpness and IS quality of this lens, a lot of photographers will line up to buy it.


The street price is $1060 (USD) and, according to Popular Photography, "well worth the price". The tripod collar is an extra $115 (USD).



The non-IS version of this lens has been hugely (and deservedly) popular with photographers. It is one of the sharpest lenses in its class, reasonably sized, not too heavy, and great to work with. The non-IS f/4 lens is also much less expensive than the bigger and heavier (and really quite wonderful) 70-200 mm f/2.8L lenses (both IS and non-IS versions).


The Canon EF 70-200 mm f/2.8L USM lens started it all. Superbly made, super sharp, and a joy to work with. It became the primary short telephoto zoom lens for a lot of photographers, myself included. Despite its fine attributes, a lot of photographers wanted a lighter and less costly version. Enter the f/4L version, smaller, lighter, much less expensive, but a virtual match in sharpness to the f/2.8 version. It quickly became popular with serious photographers who wanted a premium quality lens without a very expensive price.


Canon came out with an IS (image stabilized) version of the f/2.8L lens and a lot of photographers upgraded. A lot more photographers longed for an f/4L lens with the IS feature. That day has come.


This new lens sports the latest IS technology with a claimed 4 stop shake correction. That means you should be able to hand-hold this lens at four shutter speeds slower than a lens without image stabilization.


If you don't need the IS feature, the current version is still a great lens and you can buy it from Amazon.com for less than $600 and pay no shipping (link below).


The Canon family of 70-200 L series lenses (along with current "street" prices) looks like this:


Canon EF 70-200 mm f/4L USM (non-IS) - $582

Canon EF 70-200 mm f/4L IS USM - $1060

Canon EF 70-200 mm f/2.8L USM (non-IS) - $1115

Canon EF 70-200 mm f/2.8L IS USM - $1713


If you buy one of these lenses using the links below, you will get a great deal, pay no shipping, and help support this site.
