Go to the top Hardware:If you're thinking about going digital in a fairly serious way, here's a very comprehensive overview of how to go about it in a Canon manner, as written by Philip Greenspun (of photo.net, and Photography by Philip Greenspun)"The Canon EOS system of digital single-lens reflex (SLR) bodies and lenses is the standard choice among professional photographers worldwide. This page makes it easy to shop for Canon digital bodies and EOS lenses ... This article goes through every section of the Canon EOS system and concludes with some starter system recommendations." And here is Greenspun's Building a Digital SLR Camera System for a more basic discussion of Why Digital, and Why SLR (Single Lens Reflex)."Digital single-lens reflex (SLR) cameras are the standard tool for serious photographers. With the recent introduction of cameras such as the Nikon D80 and the Canon Digital Rebel XTi the market for digital SLR cameras has expanded tremendously. A point-and-shoot compact digital camera can offer reasonably good image quality but a digital SLR, which usually looks a lot like an old standard 35mm film camera and may use the same lenses, offers the following advantages ... " Go to the top I have a new (October 2006) Canon EOS 5D digital SLR camera body(The 5D Canon camera is sold body-only -- no lens) Full specifications (from DPReview.com) for the Canon EOS 5D
Regarding the whole shooting-RAW-versus-shooting-JPEG debate: about the very first time I used my new 5D extensively (Halloween 2006) I did something to the shooting mode dial to set the 5D into the "C - Camera User Setting" mode which is user-definable, but, if not defined, results in a default setting (ISO 100, JPEG large, 60th sec at f 5.6) that was not optimal for what I was doing: flash photography, at night, often of subjects with a very dark to black background behind them. Since a Canon RAW file is essentially an undeveloped digital negative, by setting the 5D incorrectly on Halloween night the resulting JPEGs I got for some of the shots lacked any of RAWs usual post-processing capabilities, particularly exposure compensation in the photographic sense (not merely "lighten" as can be done with Photoshop...) which would have been extremely handy for these photos. Anyway, shooting jpeg's only is *not* a mistake I'm going to make again... ...and I've made sure to set the 5D's "C - Camera User Setting" to something much more similar to what I usually want to work with, just in case :-/

Go to the top SupportBasically I've had an endless succession of cheap, rickety, flakey little tripods. No more. Bogen tripods are arguably the best there are. And now that I've bought a monopod, I find that I use that at least as much as the tripod. Monopods are essential for long-lens field sports, and I've also used it at the Blue Heron, an art gallery here on Vashon. A monopod gives excellent suppport in tight areas where setting up and tearing down a tripod would be way too risky. Tripods/Monopods: Bogen/Manfrotto 3011BN tripod with a Bogen/Manfrotto 3130 micro video head;"3011N/BN Bare Aluminum or Black Tripod - Lightweight, sturdy and portable. the 3011 is one of the easiest tripods to operate. One position leg spread, long reversible center column for extra height adjustment, and sure grip screw locking knobs are all incorporated into the classic tripod design. Ideal for 35mm and light medium format photographic cameras or video camcorders." "3130 Quick Release Micro Fluid Head - A lightweight fluid head with adjustable pan handle quick release camera plate, and secondary safety lock, ideal for cameras up to 8.8 lbs in weight. It smoothly pans a full 360 degrees, can be tilted up and down 90 degrees and has pan and tilt locks. The pan handle can be reversed for left or right-hand operation." The quick release plate gets screwed into the camera body, and allows the camera and whatever lens to be locked down onto the head in a moment, and removed just as quickly. Bogen/Manfrotto 3216 monopod with a Bogen/Manfrotto 3265 quick release ball socket head"Robust three-section Monopod featuring sure rubber grip, wrist carrying strap, quick action lever leg lock system with 45° flip, large 2.3" camera/head platform with plastic cover and dual 1/4-20" - 3/8" camera screw."

Ideal for 35mm cameras with short or medium focal length lenses." Go to the top Digital "Film"OK: so I had a digital camera. I needed some digital "film". Mainly because of cost I started out with 256mB type I Compact Flash cards, from Crucial Technologies. (The 16mB CF card that came with the camera was good for nothing more than running a picture or two up to Flash Photo). Since I shoot exclusively in Canon's RAW file format, my new EOS 5D's RAW photos are about 12.6mB each, and the EOS 10D's photos are about 6.8mB each, so a 256mB card would be good for about 16-18 or 37-39 shots in the 10D. Kinda like a 35mm camera and a 36 shot roll. Kinda also a pain in the *ss. Problem was, for anything that involved quick action like sports, drama or dance (which is most of what I shoot), I'd shoot 37-39 photos and then have to wait while the 10D's buffer emptied into the CF card, shut the camera down, pull the card, put in a new card, boot the camera, and then I could take the next shot. Subjectively it felt like minutes would go by; in actuality I would probably lose close to a minute at least, waiting and waiting and waiting... So I decided to bite the bullet and go Big and Fast and quit messing around. Currently (2006-2007) I'm using three SanDisk Ultra III 4.0gB compact flash cards for the EOS 5D, each holding about 270 Canon RAW photos, and four SanDisk Ultra II 2.0gB compact flash cards for the 10D, each one of which holds about 290 photos.I save the photos *only* in Canon's RAW file format, and convert from RAW to TIF using BreezeBrowser. Digital noise reduction for higher ISO's is done with Neat ImageHere are compact flash card timings for the EOS 5D by Rob Gailbraith at "Digital Photography Insights" Although the SanDisk Extreme III 4gB card does not seem to be the exact ones I've got, that model places eleventh in timings for writing Canon RAW files.
So the Extreme III cards are roughly 5 times faster than the Extreme II's I use in the 10D As tested on an EOS 10D, the SanDisk Ultra II 2.0gB CF card sits in the top third of the top 10% of all CF cards tested by Rob Gailbraith at "Digital Photography Insights" As he says, "... write speed differences of 5% or less from card to card in the table below should be considered insignificant. If one card's write speed is within 5% of another's, the two cards are likely to offer effectively the same performance in the real world. Similarly, it's unlikely that most photographers would notice a difference between the fastest card and one that was up to 10% slower..."
The very fastest card listed runs at 1.394MB/sec for a Large Fine JPEG write and 1.393MB/sec for a RAW file write, so I'm not far off. And man, do these cards make a difference! The biggest advantage is simply the size: at roughly 290 shots per card, I can simply wait until things calm down before I need to change cards, rather than standing there watching stuff happen I can't photograph, as I had to do with the smaller cards. And then, the SanDisk Ultra II cards are *noticeably* faster in use. I do find myself overrunning the 10D's buffer still (!) but all I have to do is slow down (or turn off the image preview ahead of time) and in actual use I rarely find myself waiting more than a moment or two before I can get the next shot off. Finally, just to confirm that "more" is never "enough" -- I do sometimes fill up all three 4gB cards at one event! That's something on the order of 870 photos :-/Go to the top My digital "darkroom"First, it's really important to understand that all this has evolved over time due to the fact that, at heart, I'm first-and-foremost a *really* hard-core computer geek :-/ The basic idea is that, with different parts of the workflow spread out over separate computers, I (or the computers) can be doing several very different things at once.
All three of the Intel boxes were purchased here on Vashon Island at Vashon IT. Check out what Matt and Greg can do for you; their prices are in fact highly competitive, and you'll be supporting an Island business.Go to the top SoftwareSo, in camera I save the photos *only* in Canon's RAW file format, and convert from RAW to TIF using BreezeBrowser. Digital noise reduction for higher ISO's is done with Neat ImageWhat's that mean? This gets into the great "what file format is best for taking/processing/saving my photos?" debate... The basic concept is that one should work in a lossless file format (TIFs, as one example) and only save one's photos to a lossy file format (JPEG or JPG as the primary example) when you are absolutely done messing with your photo in PhotoShop or the GIMP. A JPG file is by definition "lossy": every time you save a photo **without renaming the file** you are losing image quality because the JPG format is *not* intended to unconditionally preserve image data, but rather to provide a file format that can either:
but not both at the same time. With a JPG file format there's going to be a compromise, by definition. So, if you're twiddling with your photos in PhotoShop, and you save your *.JPG, and twiddle, and save, and twiddle, and save, and twiddle, you're creating a slow and significant degradation in the image's quality, probably without even being aware of it. (Which is not to say that the degradation wouldn't be obvious if you had saved a copy before you started twiddling, and then did a side-by-side comparison of the before- and after-twiddling files...) What to do? Save an archival copy of the image as a TIF; work on a *copy* of that TIF but only save in the TIF format while you are twiddling, and only convert to the JPG format at the end, and only if you *need* to for a specific purpose, say to put up on a web site. Anyway, taking one step back in the process from all that, by saving my photos on-camera in Canon's RAW file format I'm starting out with what is often called a "digital negative" -- although a RAW format photo contains far more data than any conventional negative or slide ever could. Here's a great write-up about the RAW file format, and a compare-and-contrast with the TIF and JPG format as well. And here's the nuts-and-bolts of it:
So, by shooting in Canon's RAW file format, I have a digital photograph that can be adjusted for exposure, particularly, and adjusted in a photographic sense, not just by "brightening" or "darkening" or changing the contrast in PhotoShop. Adjusted, that is, given the right software tools: RAW to TIF file conversion is done using BreezeBrowserThe image conversion software that came from Canon with the Pro90 IS was cr*p, and the software that came with my EOS 10D was worse. Way worse. It was slow, and had a "pretty" Window$ XP style user interface that wasted vast amounts of screen space on -- nothing... BreezeBrowser not only does an excellent job of converting Canon RAW files, it also is an excellent image file browser all in itself. I can have two instances up and running at one time, one looking at RAW files, and the second looking at the just-converted TIF files to decide if the conversion was successful or if I need to tweak image parameters any further. And, another excellent feature is that, given a series of photos with similar charactersitics, I can select all those photos, set the parameters for each, and convert all of them in one batch. It's not too uncommon that I convert dozens to scores of photos at one time. And digital noise reduction for higher ISO's is done with Neat ImageSo if BreezeBrowser is a really cool program, Neat Image is just shear magic. The basic concept is that a digital camera's CMOS sensor will have a consistent, given amount of digital "noise", particularly at higher ISO settings. To see an example, take your digital camera, set it to the highest ISO you have available, and shoot a photo of open, blue sky. Theoretically at very high zooms into the subsequent photo, you shouldn't see too much cruft or pixelization or digital grain. The photo *should* be pretty monotone. But chances are it isn't, and this is where Neat Image comes in. Neat Image uses "Profiles" for selected digital cameras to effectively reverse or eliminate the inherent digital noise that CMOS sensors produce, particulary at higher ISOs. Go to the top WorkflowOK. So let's get this started. Not like I don't have something else I should be doing :-/So, I take some photographs. No. Really. It's shocking, I know. First off, I've been shooting more and more in Manual mode, setting the ISO and then adjusting the shutter speed and aperture (trying to stay on or close to f5.6 for the most part) according to what the TTL meter reads. Also been shooting a lot in aperture priority AE at f5.6, focusing with a single, center focus point by holding the shutter release half-way down, and then using the Auto Exposure (AE) Lock button to set the shooting exposure after recomposing the image.
So I've got some photographs. First thing that happens in my digital "darkroom" is the Compact Flash card
comes out of the camera body and goes into a card reader hooked up to
my second Linux box via USB. The Canon RAW files are *
So the files are on the hard disk, off the Compact Flash card, and
have names something like Not real user friendly, and of no use whatsoever later on when I generate my web pages and I'll want the photos displayed with meaningful names, and in order.
So, I use the Linux/UNIX command
which says, in human, "rename all files containing the string "img_4" to the string "4" in all files ending in the string "cr2".
So now I've got a whole bunch of files with names like
which says, again in human, "rename all files containing the string ".cr2" to the string "_State_of_the_Schools.cr2" in all files ending in the string "cr2".
So now I've got files named something like A DVD. Ah, yes. That's the next step. At this point, with all the photos renamed to something meaningful I immediately burn every single one of them from the specific shoot onto a DVD. Used to use CD's, but they're too small. This is not the place to save money. I get the best DVD's I can find: Taiyo Yuden DVD+R 8x's from www.neato.com in spindles of 50. Current price: $22.00, in silver, and writeable with an Ultra Fine Point Sharpie. I also buy C-Shell CD Cases from www.neato.com as well; currently $22.46 for 100 -- I usually buy a hundred at a time. Net cost for DVD and case: $0.66, and a DVD will hold about 320 photos. Or so. I dunno, they hold a lot... So, by burning the RAW photo files onto DVD I've:
At this point I've been completely non-selective in any way: just burn 'em, and cull out the weak ones later. So the DVD goes into one of my two Windows boxes, its contents to be copied into a folder for RAW conversion and Photoshop manipulation. And ultimately, for printing. All web page generation and web site maintenance is done back on the two Linux boxes, however. So at this point I've got all the photos from one shoot on the original hard drive they were copied to; on DVD; and on another hard drive on one of two Windows boxes. Redundancy. It's called redundancy. Or, as Jerry Pournelle used to say in Byte Magazine 'way back in the '80's: "Back up early and often". And, the Compact Flash card(s) from that shoot are formatted in either the 5D or the 10D before they're used again. I always reformat my Compact Flash cards after every use.
