Enabling Colour Profiles in Firefox

Up until recently I've been calibrating my monitors (HP LP2475w) with the Spyder2Express.  Now, this is quite an inexpensive unit, and when I first bought it, I didn't really know much about calibration.  It doesn't (officially) support multiple monitors, although there are pain-in-the-ass workarounds that can make it happen (although the whole process can take up to an hour to sort it out each time you need to recalibrate).  So, I only ever calibrated my main monitor regularly, the one on which I edit my photos and watch video previews while editing, the other screen being resigned to simply displaying palettes and other program info.  But it's also the screen on which I browse the web.

Anyway, after going to the Focus on Imaging show last month, and picking up several 100-sheet packs of Ilford Galerie Smooth Pearl and Harman Crystaljet Luster paper I decided it was about time I got a bit more serious about my calibration (and I really wanted something that would allow me to calibrate a multiple monitor system without all the farting around).

So, I went ahead and I bought the X-Rite Eye One Display 2, and how sexy it is.  I bought it from a company called Native Digital, on the recommendation of a friend who had used them in the past.  When you buy the Display 2 from them, they also throw in two free printer profiles (normally £15 each), so as I'd just got new papers for the printer, it sounded like a great deal to me.

Unit arrives, bit of screwing around to figure out how the software works, and I have two beautifully calibrated virtually identical screens sitting on my desk.  I save an image out of Photoshop, using the sRGB colour profile via "Save for Web and Devices", upload it to Flickr and... hold on a minute... why does it look different to the image in Photoshop?

So I did a little digging, because I could've sworn I read that FireFox 3 supported embedded colour profiles within images.  Turns out, it does, although it's not enabled by default, which means that everything is being shown with your standard calibration, and not necessarily how the photographer intended it to be viewed.

After a little more digging around, I discovered that there are a couple of plugins that claim to enable this feature for you, as there is nothing in FireFox's "Options" dialogue, nor any of the menu options.  The plugins didn't seem to do a thing for me, so I deleted them, and I can't really tell you what they were, you'll have to hit up Google if you're curious. Eventually I did manage to find a solution (which is a lot less hassle than downloading and installing a plugin to be honest with you), which I'm going to pass along right here.

WARNING : You can seriously screw up your FireFox configuration if you change something in here you're not supposed to change, so I take no responsibility for anything YOU do with YOUR computer. :)

That said, this is what I did, what worked for me, so here it is.

When facing the Firefox browser window, you want to enter "about:config" into the URL bar.  You will be then confronted with a warning as shown in the image below (remember, I told you, not my fault if you screw something up.  If you're not sure what you're doing, don't do this!).

Clicking the button to continue into the configuration presents you with hundreds and hundreds of ways to screw up your settings...

So, let's narrow things down a bit.  You'll want to start by entering "gfx" into the "Filter" box shown at the top of the page, and the option we're going to be editing is highlited in the screenshot below.

Simply double click on this line to bring up the dialog box.  When the box comes up, enter a value of "1", and click OK.

Now, your list should look lke this.  The "Status" till change from "default" to "user set" to show that the default value has been edited by the user.  If you do screw something up, this could help you to find those settings you changed and assist you in resetting them.

Now just restart FireFox (although, I'm not even certain this step is required) and you're all set.  Your images with embedded sRGB colour profiles (as the vast majority of photos on the web are) will be displaying their correct colours on your beautifully calibrated screen.

Dell Zino HD (Take Two)

As I type from my laptop while up in the bedroom, I'm watching my replacement Dell Zino HD (see previous post) go through its "Windows Experience Index" tests. I don't expect any spectacular results, but I am curious. I notice that in Windows 7, the maximum index has been upped from Vista's 5.9 to 7.9. So, have a watch of this again while it's running.

No surprise, it just finished and came up with a rating of 3.1, which is determined by the lowest score, which was the graphics card.

• 3.6 : Processor - Calculations per second
• 5.0 : Memory (RAM) - Memory operations per second
• 3.1 : Graphics - Desktop performance for Windows Aero
• 4.8 : Gaming graphics - 3D business and gaming graphics performance
• 5.9 : Primary hard disk - Disk data transfer rate

So, overall, a bit better than I expected, but still nothing amazing.  I don't expect it would handle something like World of Warcraft in its current state.

This article is really about the ease of setup and general information regarding my experiences and first impressions with this device.  I'll post again in a couple of weeks and let you know if I still think it seems like a neat bit of kit.  I'm treating this as a sort of "for dummies" exercise, as this is just going to be a media center, and will not really satisfy any of my usual PC needs (except to maybe play the occasional Youtube video full screen on the TV) so I don't want to have to go in-depth with this machine to sort out any of the troubleshooting issues that usually come with setting up a new PC.  I want this to be smooth and easy.

The box is very small.  It has a footprint of about 8"x8" and is only about 3.5" high.  Great looking little box besides the TV, and it's almost completely silent.  As the box is so small, there's no room for an internal PCI TV Tuner card, so I picked up an external Hauppauge WinTV USB stick, which is currently attached to the PC via a USB extension cable and gaffer taped to the top of the TV in order to be able to see the remote control (I'm definitely going to have to work on an alternative solution for that one).  Now to find out if the CD that comes with the WinTV is really as "Compatibly with Windows 7" as it claims.

Well, plugging in the device did fire Windows into life, and while it did not detect a driver available for automatic installtion, a screen popped up that sent me directly to a download from the Hauppauge website.  I didn't even have to go sifting through pages and pages of support; I just click the link from within Windows and it asks me to save a file.  Drivers extracted into a new folder, and Windows now tells me to click the setup file.  All good so far.  And there we go, drivers installed without even having to take the supplied CD out of its packet.

I'm going to assume that this has not installed Hauppauge's own TV software, which is perfectly fine with me as I plan to use Windows Media Center anyway.  The only reason it's been needed in the past on XP and Vista setups is in order to be able to utilise the IR remote control.  Let us hope that all goes to plan.

Batteries in the remote, point it at the TV, press the green button, and.. oh.  That was unexpected.  It told the PC to shut down.  Or, more correctly, it seems to have put it into sleep mode as pressing it again powered it back up without issue.  Let's try that again, with the "Go" button this time. Up comes Windows Media Center.  Success!

Setting up the TV section seems to be going smoothly.  It's detected the WinTV USB stick, has seemingly downloaded my 14 day program guide and is currently scanning for channels I can receive.  I must say that I have the device plugged into the aeriel on the roof, and not the little portable antenna that's packaged with the device (which has often proven in the past to be just a tiny bit worse than completely useless).

Now this is interesting.  Loading up the program guide shows that I can get Sky Player, let's give it a whirl.  Create a Sky ID, done.  Login, done.  Play some Sky News.  Nothing, black screen.  Click back, lots of flickering through different menus and confusion.  Nope, guess that's not working.  I'll have to do some digging on that later and get back to you.

Switch over to Dave, and there's...  Sorry, got distracted there watching Top Gear until Sun came up and asked me if I wanted to allow automatic updates to Java.  I imagine I'll be getting these for a couple of days as various things come to action and expect me to do something about it.  Well, never mind, it's repeated on Dave Ja Vu, so I'll just set it to automatically record.  Oh, new interface on the recording options since Vista Media Center.

The interesting thing so far, is that I've not had to touch a keyboard or mouse since installing the WinTV, except to enter my postcode when setting up the TV listings guide.

But anyway.  More on the Dell Zino HD in a couple of days.  The Top Gear show I was half-watching is about to start over on Dave Ja Vu, so I'm going to watch a DVD and let it record in the background.  Let's see if it can cope. :)

Dell Zino HD

I hadn't heard about Dell's new Inspiron Zino HD before, but while wandering the aisles of the local PC World to find a new PC for my wife, I ran across one on display and thought "Hey, that's a neat little box.  Could replace the PC that just died in the bedroom".  The PC in the bedroom is actually an HTPC, one of three PCs we run as HTPCs on the network, so that they can all access programs recorded by each other.

So I decided to go ahead and get one, along with the PC the wife had picked out, a wireless multimedia keyboard and a Hauppauge USB Dongle.

It wasn't the top of the line version with all the optional extras (Blu-Ray, larger hard drive, 8GB RAM, WiFi, etc), but it didn't need to be.  The TV in the bedroom is only 720HD, and it hooks up just fine through the HDMI.  It didn't have the TV Tuner card inside it, but a couple of aisles over I picked up the Hauppauge Win-TV USB stick with remote control (not the one shown on the site, we got the one that actually looks like a regular TV remote control).  Mass storage of recorded TV is all done on a central server so that all three HTPCs (as well as any other PCs wired into the network, or wireless laptops & devices) can access it all, so I wasn't too bothered about the fact that the hard drive was a mere 500GB.

I was so excited, I unpacked the base unit out of the box, along with the power adapter and started to plug it all in.  I had my own wireless keyboard and mouse for the bedroom already, so I didn't bother to unpack those.  I'm still using XP or Vista on most of my machines here so this was my first look at Windows 7 too.  As I said, I was quite excited.

I hit the power button and up it comes on the 32" Bravia mounted on the wall; It even detected it as 1360x768 resolution (which is near as good enough to 16:9) and not the 1280x768 16:10 resolution it normally detected (thus squashing TV programs and DVDs slightly) when hooked up to a PC via the VGA cable.  I was suitably impressed.

Shiny new loading screen from Windows 7, still impressed.  Then, all of a sudden, for no reason whatsoever, the system decides to reboot and I see the all too familiar "Windows failed to start correctly" screen (or words to that effect), and options to boot normally or boot into safe mode.  I figure it's just a fluke, and tell it to boot normally.  It gets halfway through the boot sequence again, restarts and no longer detects that there is a hard drive connected to the system.

So, to my dismay I package it all back off and trek back down to PC World, not a happy bunny.  I was even less happy when they told me they had no more in stock, only the display model.  So, now I have to wait until they can get a replacement machine into the store for me to pick up on Monday.

Not quite the post I was hoping to make when I handed over my credit card at PC World, but hopefully on Monday, I my will be faith restored.  This is the first time in about 15 years though that I've seen a Dell die so soon after coming new out of the box.

The wife, on the other hand, is currently installing World of Warcraft on her shiny new PC.  No doubt she'll be having me restore her system from the backup DVDs within a week or two. :)
