GIMP

Software

Great price beats Photoshop.

Stupidly named, GIMP, or “The GNU Image Manipulation Program”, this Mac application does itself no justice with that dumb name. It’s a fine alternative to Photoshop for users who, like me, detest the user interface of that Adobe application and like the ridiculous price asked even less.

One of the reasons I still make do with Photoshop CS2 (an older version of the current CS4 which runs under the Rosetta PPC emulator in Snow Leopard) is that the upgrade price makes no sense for this photographer who gets most of the tools he needs in Lightroom and basically roundtrips to Photoshop from Lightroom to fix converging verticals and pincushion and barrel lens distortion. (Try Canon’s 24-105mm at 24mm to see real barrel distortion).

The problem is that Snow Leopard suffers from a huge problem in the Rosetta emulator, as widely reported on Apple’s Discussion Forum. Rosetta applications are prone to spontaneously reboot your Mac! This has happened to me on all three I run – Quicken 2005, Excel v.X and Photoshop CS2. It has never happened with any Universal/Intel applications. Maybe Apple will admit error and fix this. Who knows? More likely they will just tell users to upgrade to Universal versions of the affected applications (impossible with Quicken where none exists, by the way).

GIMP fixes all of that. It’s a Universal application so there are no Rosetta issues. Exporting to GIMP from Lightroom is merely a question of setting Lightroom’s Preferences->External Editing to use GIMP as the external image editor. Then hitting Photo->Edit In->Edit in GIMP in LR moves a TIFF copy of your image to GIMP for distortion or perspective correction. Correction is applied in Filters->Distorts->Lens Distortions (for lens distortions) or in Tools->Transform Tools->Perspective to fix leaning verticals. Unlike in CS2, there is no need to create a Background Layer when doing the latter – it’s much easier in GIMP. When you tell GIMP to save the processed picture it will save it right back into Lightroom alongside the original, in a stack. Just like CS2.

GIMP can only handle 8-bit files. I have experimented with it and compared output to the 16-bit ones from Photoshop and cannot tell the difference in 30″ x 40″ prints. You can read lots of technical articles explaining why 16-bit is better but not a one of those will be illustrated with the only thing that matters – real pictures. The Label Drinkers are at work again.

Here’s a ‘before’ and ‘after’ showing the use of perspective correction to get rid of extraneous detail on the right of the picture – I simply could not get into a better position from which to take this:

Here’s the ‘after’ image:

Morro Bay at sunset. 5D, 24-105mm @ 105mm. Perspective corrected in GIMP.

The price of GIMP? How about free?

You can download it here and it runs fine on Snow Leopard 10.6.1. If you need the Help file, that’s a separate download (strange) but it integrates nicely. Just use a keyword search to find what you need after invoking Help from within GIMP.

Friend of the blog Greg Littell has pointed me to a couple of useful links. To make GIMP feel more like Photoshop and to use your old Photoshop plug-ins, click here. For a complete directory of hundreds of GIMP plug-ins, click here.

Snow Leopard coming around

OS X

Compatibility issues are quickly disappearing.

Six weeks ago I cautioned against an early upgrade to Snow Leopard largely on grounds of its lack of compatibility with many common applications.

Having tried SL 6.1 on my iMac I can report that most of the most commonly used applications I use now run fine. It’s especially satisfying to see that legacy PPC applications (ones written for the old Macs using the IBM G3/4/5 CPUs) run really well under Rosetta, though why on earth Apple makes Rosetta an optional install which you have to search for (under ‘Customize’) beats me. Most specifically, Photoshop CS2 runs perfectly and I have no need or desire to pay Adobe for a later version given my limited PS use. And yes, I still run ancient versions of Microsoft Word and Excel as they do all I need and I simply hate paying Microsoft for anything.

Lightroom in 64-bit mode runs fine and, once again, it’s a wonder to me Adobe doesn’t simply detect 64-bit systems automatically rather than insisting on installing in 32-bit mode by default. The switch is beyond obscure – right click on LR in Finder and uncheck the ’32-bit’ box. Jeez! To confirm you are running in 64-bit mode, switch on the splash screen to make it show when LR starts (it’s under ‘Preferences’) and you should see the ’64-bit’ narrative there.

Why switch to Snow Leopard at all? Because sooner or later it will be mandatory as older OS version are supported less and less. Do it now and it’s easier. Do it later and lots of things have to be fixed all at once. And Apple does a decent job in major OS revisions (Panther->Tiger->Leopard->Snow Leopard) that once they are past the first or second version things tend to run pretty well. They have for me.

Now if we could only get the likes of Adobe to rewrite their applications to properly use multi-core CPUs and all that 64-bit goodness, wouldn’t life be sweet? Unfortunately, one of the sadder aspects of the gradual demise of Aperture is that Adobe has less competition. Would that Apple bought Adobe (chump change to Apple) and brought some modernization and proper user interface design to Photoshop, though why anyone would want the aggravation of all those angry help calls from Windows users beats me.

But look, I’m not grumbling. Lightroom 2.5 runs just fine with Snow Leopard. For that I am sincerely grateful.

There’s actually some pretty interesting technical information on 64-bit technology and related developments to be found on Apple’s site which those so inclined can find by clicking the picture below.

Lightroom wins

Lightroom

Aperture is dead in the water.

Having started serious volume digital photo processing with Apple’s Aperture and finally made the switch to Lightroom almost two years ago, the following data recently released by Adobe hardly surprise me:

Clearly, I’m not the only one making the move, especially if you take into account the large increase in Mac sales in the past few quarters. Forget the upper table – Aperture does not run on Windows so it’s not a fair comparison. The lower table is.

When did you last hear of a meaningful update to Aperture or see any advertising for the product?

Those still using Aperture should be getting worried and would do well to consult my earlier piece on abandoning that major stress source for Mac performance. Aperture is another orphan application which couldn’t handle the heat in the kitchen. It’s future is …. well, what future? Have you noticed how Aperture does not even support Panasonic G1/GH1/GF1 RAW file import – maybe the most signifiant camera design to hot the market in the past year? That makes me think it’s a dying application, starved of capital as Apple concentrates on making …. cell phones.

It bears repeating – the user interface in Lightroom is not only logical and linear, it actually makes photo processing fun. That’s not something I thought I would ever write. And you don’t lose track of originals or accidentally erase them, either.

Spam in the RSS feed

Software

Spam, spam, spam, spam, spam eggs and spam.

Putting aside the Monthy Python quote, above, readers using an RSS feed (such as Google Reader, NetNewsWire, Vienna, etc.) will have noticed that yesterday’s postings had summaries inundated with spam. This spam appears to advertise stimulants which readers here have no need of, this blog offering a natural high.

This is what it looks like:

Mercifully, my RSS feed only contains a brief extract of the posting so the schmuck who did this doesn’t get his click-through link to show up. I reposted the piece under a different name but no joy. The same spam in the summary field showed up.

Some very smart people are on to this and I found the fix on Anwyn’s Blog which I recommend if your blog is similarly afflicted.

Suffice it to say that the problem is fixed and the revised posting of yesterday’s piece now looks like this in the RSS reader:

Unfortunately, there’s no way of deleting individual articles from the RSS history but at least newer pieces are now shown without spam, viz:

Snow Leopard – Just Say No

OS X

Serious compatibility issues.

Apple has said that its 64-bit OS, Snow Leopard, will be on sale August 28. You know – all the usual twaddle – better, faster, smaller, etc. Just pay up, please. The cash register is right over there. We gotta keep those analysts on Wall Street happy. Goodness alone knows what additional stress the 64-bit OS places on already overtaxed graphics circuitry in overheated, poorly ventilated boxes. And excuse me, but just how many 64-bit third party applications are out there and don’t these need 32gB or more of RAM to show any benefit? Once again, it seems, we are being offered a Ferrari to do the grocery shopping, because the racetrack is closed.

Come to think of it, I’m still trying to figure out what, if anything, the ‘upgrade’ from Tiger to Leopard did for me, other than a butt ugly purple login screen. At least our machines did not fry under Tiger.


Snow Leopard (in)compatibility list – extract

Unless you are positively insane or unless you have checked this compatibility list and are willing to believe what you read, you really should hold off upgrading, no matter how cheap it is.

Older PPC applications like Adobe Photoshop CS2 (will not run) and Intuit’s Quicken (Intuit says it will run but they are a business which shares business morals with eBay and PayPal – no earthly way you can trust a company that disables its software every other year to force you to upgrade) are problem areas. I don’t know about you but I am not about to shell out hundreds of dollars on the latest version of Photoshop which does nothing for me, or trust Intuit, only to do my photo processing or mess up my on-line banking.

But there are bigger shockers in this list. SpamSieve, the ne plus ultra of email spam apps, superb in every way and leaving Apple’s Mail Spam function in the dust, will not run. Photoshop Elements will not run. Really! Disk Warrior (serious $) will not run. MenuMeters will not run. NeoOffice may not run (the thinking man’s free alternative to the garbage called Office from Microsoft). SafariBlock – a key ad blocker for me which stops all ads, including those irritating flash ads – will not run. SmartScroll will not run. Dozens of others are in ‘Unknown’ status.

And no news of all those fan (Fan Control, SMC Fan Control) and temperature measurement (Temperature Monitor) utilities which are essential to stop your Mac from frying. What if they don’t run? And what if your new OS fries the GPU twice as fast as the old one, seeing as Snow Leopard is meant to be so much faster?

Well you get the idea. Updating now is simply crazy. Let the guinea pigs who see no wrong in anything Apple do the bleeding for you.


Snow Leopard – run away fast or it will bite you in the rear.
