I agree with Burkphoto.

As to setting white balance, I have used an expo disk for years now.

You can use an 18% grey card, or a white card and sometimes it turns out correct while other times it's not. On the other hand ever since I started using the expo disk I've gotten perfect and consistent results.

It comes in a case you can hang on a belt. I hand mine on my camera case so that it's always with me. They're not very expensive and I think are worth their weight in gold.

If you do buy one, get one for your largest filter diameter. It will then snap into that and for lenses with a lesser diameter you can always hold it when doing a white balance. You're only holding it for two or three seconds.

I have the ExpoDisc, a Delta-1 Gray Card, and a One Shot Digital Calibration Target from Photovision. All work well, but in different situations.

The ExpoDisc works well when you can use the camera the same way you would use an incident light meter or incident color temperature meter. For best results, you must point it at the predominant light source from the subject's point of view, back towards the camera.

If you fill the frame with a gray card, meter on auto, then set manual exposure from the readout on the LCD from a frame exposed on auto, then custom white balance from that, the gray card works well. Same for the One Shot Target, which gives you a "three stripe" histogram. Center the histogram to establish exposure, then set custom white balance from a frame of it.

Pre-set your camera controls in the submenus first, for color tone, saturation, sharpness, hue, curves (Picture Styles), and so on. Then do the exposure and custom white balance checks.

Color management is a system. If any part of the system is not managed, you will get unpredictable results.

The camera has an sRGB and an Adobe RGB (1998) profile setting. Unless you are using a very high end printing system, you will get more predictable results with sRGB. Note that in RAW mode, this is just a reference tag in the metadata (like many other camera parameters, it just controls the look of the reference image when you open the RAW image in a RAW image editor). But when recording images In JPEG mode, this profile setting becomes the actual ICC color space of the image!

RAW images do not really have profiles. They do have camera characteristics recorded in Apple's Mac OS X and in Adobe's ACR module (used by Photoshop and Lightroom).

A properly calibrated and then profiled monitor will have an ICC profile stored in the operating system. Your system has color management settings in it. So does your software. Spend time learning how to set these!

You will also need an output color space setting when saving images. You can default to something like sRGB, or (if you're converting from RAW, or used Adobe RGB at the camera) Adobe RGB, or a lab profile if your lab gave you one...

The system begins with custom white balance — IF you are using the JPEGs you capture. It can start there in RAW mode as well, if you don't adjust color temperature in post-processing.

Yes, you need a WhiBal, or ExpoDisc, or One Shot Digital Calibration Target, or a Delta 1 Gray Card, or similar tool as a reference for both exposure and white balance! If you are going to adjust color in RAW mode for accuracy, that's where you need the ColorChecker Passport.

But really, why would you not calibrate your monitor? You should not attempt to adjust color without a properly calibrated and profiled monitor, and should not print without using the proper profile for your particular printer, ink, and paper combination.

When Apple switched from the Motorola cpu to Intel, they stopped supporting the older Macs and Power PCs. Yes my Power PC still works but none of the updated software will run on it. The latest versions of PS, Open Office or Microsoft Office can not be loaded or run.


It was worth the shift. Motorola was never going to create a G5 processor for a PowerBook. The 1.67 GHz PowerBook G4 ran *very* hot (I had one). A G5 would have fried eggs (and fingers!) and would have required a 3X to 4X larger battery. No one would have bought it.

Also, the PowerPC RISC architecture seemed to have a "heat limit" that was effectively a "speed limit". They were not going to surpass 3 GHz without some very tough challenges! (Remember the liquid-cooled 2.7 GHz Power Mac G5? Many of them sprang leaks over time!)

So Steve Jobs had to do something. He and his team had a good relationship with Intel since their days of making the NeXT software run on x86.

Intel showed Apple plenty of forward thinking designs. As they had done a few times previously, Apple developers built a migration path for their OS, and for users' legacy software, so we were not stranded immediately. Just as OS X 10.4.11 was the last Apple OS to run Classic Mode (OS 9.2.2 applications), 10.6.8 was the last Apple OS with Rosetta, an emulator that could run apps built on PowerPC code. 10.5.x was the "bridge" OS that ran on both PowerPC and Intel chips.

When I bought my 2008 MacBook Pro with Core 2 Duo 2.6 GHz processor, it rendered video FIVE TIMES faster than my 1.67 GHz PowerBook G4 did. Everything else ran 2.5 to 3.5 times faster. I saved so much time (time is money) that it was more than worth the hardware and software upgrades and replacements.

Yeah, I still miss PageMaker, so I keep an accelerated Power Mac G4 around to run it natively, in OS 9.2.2. I never liked what Adobe did with InDesign.

So tell me how Apple is better now that they use Intel 86 processors which MS PC use the same processors and main PCB and such hardware?


Apple specifies all the hardware components, then writes drivers for every one of them (or works with the hardware supplier to write the Mac OS X driver for that specific component).

Because the same company creates the hardware design and writes the software for that design, and because they limit their offerings to just a few models in each category, they are able to maintain very tight control over quality. Bugs get found and squashed relatively quickly.

That said, I always like to get a machine with a "Rev. B" or "Rev. C" motherboard, and take the 10.X.3 or 10.X.4 version of the new OS X. Inevitably, 10.X.0 and 10.X.1 will have issues. Be it ever thus with ANY OS software, from Apple, MS, or Linux. WinXP Service Pack 3 was finally pretty stable, as is Mac OS X 10.6.8. But any software that is ever COMPLETED is also ABANDONED.

UHH needs a button an OP can hit to end and archive the discussion. After a while, many discussions deteriorate into a repetitive skush pit of the same sort of whining, or "Ford vs. Chevy" or "Mac vs. PC" (There's one of those going on now, in fact!

Two words: 'Genius Bar' if you live somewhere near an Apple Retail store, then you have free access (yes, FREE) to a youngish geek who will very patiently explain your hardware and or software issues/challenges or just show you how to use it. Plus in store classes and etc. I dropped into an Apple Store to pick up a Mac Book Pro for my wife on Christmas Eve and asked the sales person why Apple Pay wasn't working on my iPhone 6? Not only did they obsess figuring out my issue (I had my location set as South Africa which explains why the maps where all in kilometers DOH!) but the sales guy noticed a crack in the screen and said: "this is a single line crack on the corner with no obvious Impact which falls within my discretion to fix for free. Can you leave it here for an hour?" Totally! (And for the record, I had dropped the phone on stone steps with a very thin case on it; totally my fault). I used to work for HP but now have 3 macs, an iPad mini and an iPhone. Yes, Virginia, PCs are cheaper, but with Apple, there really is a Santa Claus ;-)

I'm sure this is all true, folks. They've been golden to me over the years. I had a 2005 PowerBook G4 that developed funny, colored vertical lines on the screen — 43 of them! I took it back to the Apple Store, argued my case that it was a known problem (there was an Internet database of hundreds of cases), and they fixed it free of charge, replacing the screen and some driver board, even though the issue was caused by defective THIRD PARTY memory DIMMS that I installed! (I sent the memory back to Kingston and they overnighted me replacements.)

Another time, my MBP had an issue with the nVidia video chip that failed and rendered it useless. I got a free motherboard replacement, even though the Mac itself was out of warranty.

All I had to do was ask nicely.

These were exceptions. Most of the Macs I've encountered were problem free for at least five years. We still have a Power Mac G3 from 1999 that works fine. We keep it to run obsolete software such as PageMaker 6.5 and Macromedia Freehand 11.

My Mac SE lasted from 1986 – 1994 (retired, still working).
My PowerBook 540 lasted from 1994 – 2000. (still working, on AC only)
My PowerBook G3 lasted from 2000 – 2009. (still working, on AC only)
My PowerBook G4 lasted from 2005 – 2012 (or longer; I left the company.) (battery lasted five years)
My MacBook Pro lasted from 2008 – 2012 (or longer; I left the company.)

My 1990 Genesis PC lasted nine months (motherboard meltdown)
My second 1990 Genesis PC lasted three years (hard drive failed; would not boot with new HD)
My 1994 Genesis PC lasted four years (power supply and motherboard meltdown — no discernible cause)
My 1998 PC, a Gateway, lasted two years (motherboard failure)
My 2000 Gateway E Series lasted four years (still worked fine when I turned it in to IT)
My 2005 Dell D610 lasted until 2012, but needed a new hard drive, memory expansion, and battery in 2010.

I'm typing this on a Mac Mini from late 2010, which has needed only a replacement DVD drive that I picked up on eBay for $35. I wish I had three more of this particular Mini!

Yes, I go along with this and what Gene51 posted. I think this old, old argument is a bit like choosing to wear designer jeans. If you want the cachet of belonging to a smaller herd and want to pay the extra, go with the MAC, no doubt it will work for you.

From a hardware perspective and since Apple were obliged to move over to Intel processors, there's nothing to choose between the two apart from price. There is a difference in the O/S but again, it's just six of one and half a dozen of the other and mainly comes down to what you've got used to.

In the same way that folk tend to maintain that their choice of camera system is the best (no one likes to admit to a mistake), the MAC user will always claim that illusory high ground. By the same token and as a committed PC user, I'm always going to claim my choice is better; at least I can prove it's less costly and more flexible with wider choices.

There is the argument that MACs are less subject to viral attack by “security through minority” which has some truth in it although viruses on MACs are a reality, they are not as common in the profit-driven world of malware. Having said that it's pretty easy to make your PC bombproof by using software like Deep Freeze and/or a virtual machine without resorting to expensive and resource consuming AV solutions.

Windows machines are targets of over 100,000 viruses. When I worked at a large lab, we had several instances where a virus took down the entire operation — over 150 Windows computers — for a day or more. We had Symantec AV running on every Windows box, and still got hit, multiple times!

We never had any issues on any of our Macs, which NEVER ran ANY anti-virus software.

The Mac OS X system is based on UNIX, and has several layers of extremely good anti-VIRUS protection built into it. If you can name ONE actual, successful *virus* attack *in the wild* on OS X, I would love to know what it is. When people ask the same in computer forums, the answer is usually, "Umm... Uhh..." and they point to what's actually *Trojan horse malware*. Big difference!

Macs themselves simply have not been the targets of *successful* *actual VIRUS* attacks.

Mac MS OFFICE has been subject to MS Office Macro viruses from time to time (they rely on Visual Basic, and work the same across platforms). However, these are going to screw up Office data files, and not the rest of the Mac system. You can protect your Office system by locking the Normal.dot(x) template, and any other templates you use.

Just like Windows, Macs are vulnerable to various "Trojan horse" malware schemes, but on the Mac, these require users to do something to "invite" the invader into the system by clicking on an installer button of one sort or another, and then entering an Administrator password! True viruses install themselves.

If you run Windows on your Mac in Parallels or VMWare Fusion, as I do, be sure that the Windows instance is protected with AV and anti-malware and anti-adware packages, the same as it should be on a stand-alone PC.

I always had both a Mac and a Windows box in my office from 1990 through 2008, when I sucked my Dell Latitude D610's hard drive into my Mac with Parallels Transporter.

I used the Mac because I wanted to, and Windows because I needed Windows software such as AS/400 Client Access, various HR time keeping systems, Kodak DP2 Print Production Software, the Windows version of FileMaker Pro, and various company proprietary applications. All of these ran fine on the early 2008 MacBook Pro, in emulation. In fact, running Windows on the MBP was about 2 to 2.5 times faster than running it, and the same apps, on the (admittedly older) Dell!

So I was happy to have just one computer to carry, with my entire suite of training content creation and delivery tools in it. I could cut and paste between operating systems, do still and video screen captures from either operating system, edit videos, audio podcasts, still images, and PowerPoints, and handle every database update chore I needed to handle, all in one box, and back it all up to one external drive.

There is absolutely no comparison when it comes to ease of use, AT THE OS LEVEL. The Mac is layers and layers of elegance deep. When you get a Windows error message, it is technically correct, but functionally useless to anyone but a programmer. When you get a Mac error message, about nine times out of ten, it TELLS YOU WHAT TO DO TO CLEAR THE PROBLEM.

I've seen Windows users move to the Mac and get confused at first, because what took ten steps in Windows only takes about three in OS X. The simplicity takes some getting used to.

I've had folks come up to me a year later and tell me my advice to "Get a Mac" saved them hours of agony, and enabled them to do things they hadn't thought possible. My own sister, a municipal judge, can use an iMac just fine, but won't touch a PC at the courthouse unless she absolutely has to.

Mac users ARE willing to pay more. The total cost of ownership over the full life of the machine is usually less than it would be for a comparable PC. The upfront cost is higher, the service and repair costs lower. Add-on costs are usually lower, since most Macs already come with what you need. In a corporate setting, there is much less support needed for Mac users, unless they run Windows, too. Then, it is about the same.

In my 28 years of using Macs and PCs, I've spent far more time fooling around trying to get a PC to work the way I needed it to work than I had to spend to get the Mac to work the way I needed it to. I've spent far more time USING the Mac, because I don't have to THINK about using it.

The Apple "walled garden" may offend some developers and power users who just want to do their own thing. Yet there isn't much snob appeal in it — Those of us who see computers as tools that should never get in the way of the task are happy to have Macs, and the premium that saves us the time, energy, distracting thought, and frustrations certainly is worth it.

I should have mentioned that if you don't have Adobe Acrobat Professional, Preview can do a lot of routine things that most folks would use Acrobat to do.

The image editing tools in Preview are very simple, however. If you want to edit RAW images creatively and precisely, you would be better off using Adobe Lightroom. It has many more controls and tools.

I learned my lesson about lens hoods and UV filters on the sidelines of my high school's football games back in 1969... My brand new Nikkormat Ftn and 135mm f/2.8 lens took a direct hit from an errant pass. I lost the shade, but the filter just got muddy. My friend at the camera store had been right.

I've run Windows on my Macs since 2000. The old PowerPC world's Virtual PC emulator was slow, but the modern Parallels Desktop running on Intel Macs is FAST. I gave up PCs in 2008 when I got a MacBook Pro with lots of RAM and disk space. I ran Mac MS Office and Adobe apps, and Windows Outlook and proprietary corporate apps, all at the same time. ZERO issues.

The above reply is incorrect.

The RAW processing capability is provided by an Operating System Program called Digital Camera Raw in the update list. Dig Cam RAW is available to Aperture, iPhoto, Image Capture and other programs.


Preview uses it, too. Mac OS X Preview is one of the most versatile and useful bundled apps that comes with a Mac. It's so useful, I set it as my default program for viewing JPEGs.

If you are a Mac user and haven't discovered what you can do with Preview to create and edit PDF files, do some Google searches for how to manipulate PDF files in Mac OS X Preview. You can turn your photos into PDFs, add text annotations, add and remove and rearrange pages, etc.

It depends on what you mean by 'better'. Optically, there is no such thing as a filter that will improve your images by adding anything to them. Filters remove light. In some situations, they can improve images by doing so. Light that is of unwanted wavelengths or polarization, etc. Or even just getting rid of some light 'across the board' to allow longer exposures.

That said, I do tend to keep UV filters on my lenses (unless I'm shooting with a polarizer or ND filter) for protection against stuff getting on the front element. If I clean a filter and a piece of grit in whatever I was cleaning off scratches it, at least I haven't scratched my front element. All I ask of them is that they not send light where it doesn't belong. To this end, muticoatings and well-polished and flat glass are desired.

They usually have no discernible optical effect, but on a hazy day they may cut through the haze a bit. This was a more useful effect in the days of film because most films were more sensitive to near UV light (relative to their sensitivity to visible light) than most IC sensors are. Getting Silver halide films to be anything like as sensitive to orange and red light as they are to blue and violet (and especially UV) light was one of the big challenges of the first 2/3 of the twentieth century. Getting Silicon based sensors to be as sensitive to blue and violet light as they are to red and IR has been a challenge for the last couple of decades.

Yeah, and Infrared Ektachrome was one of my favorite films for 1970's psychedelic false color landscapes! It was a pain in the patoot to handle, though (keep frozen until six hours before use, load in total darkness, process ASAP after use...). It was supposed to be used with a #25 Red filter over the lens, but could be used with other filters for stranger results.

Protective glass is useful when you need it, but I never use it in the studio unless the subject is likely to damage my lens.

I once lost a UV filter at a welder's scene I was photographing in our company shop. A piece of the hot metal broke off, flew into the camera, and cracked the filter. I was glad to be working on a tripod with a long cable release. The welder had warned me that might happen. At least my lens was intact!
