Cleaning Out iDevice Cruft From My Mac

Poking around my Mac laptop, I came across

and found thousands and thousands of logs and crash-reports for various iPhone/iPad applications that have been accumulating over the years. You'd think that iTunes would clean this stuff up after a while. I deleted it all.

Elsewhere in ~/Library/Logs/ I found random cruft, some dating back three generations of laptops, to 2003.

I deleted it all. It felt satisfying.

Can anyone recommend a "keep things tidy" app, along the lines of Crap Cleaner, which I used to use when I had a Windows box?

Adding a CPU Chip to a Nikon-Mount Voigtländer 125mm f/2.5 Lens

UPDATE: Sadly, the procedures reported on this post ended up not working. More info here.

I'll leave the whole post, including the inline updates, but be warned that it was all for nothing. )-:

As most folks guessed correctly in my golden bumpy "What am I?" quiz, the object is a lens CPU chip/contacts set. I'm surprised so many people knew what it was because I had no idea they existed until recently. It allows one to update an old lens with modern electronics that tells the camera body a few particulars about the lens.

By far my favorite [...]

So Much For That Glorious iPad Screen: iOS and its Apps are Not Even Color Managed

Well, this is surprising: iOS does not seem to be color managed. At all.

This is a long and technical article. Here's the table of contents:

Introduction Color Management Embedded Color-Profile Support Device-Specific Color Profiles The Curiously-Deficient "SpyderGallery" App What's Next One Last Caveat

Introduction

With all the talk these days about glorious color performance of the third-generation iPad screen, such as this article and this, I realized that my Lightroom-to-iPad workflow (presented in "Getting Photos from Lightroom to iPad: a Much Smoother Workflow") neglected to consider color profiles. This is a huge oversight for someone like me [...]

Funky Kyoto Marathoners: More Lightroom Processing Fun (and a mini challenge)

So I was going through the photos from last weekend's Kyoto Marathon (京都マラソン2012) and came across an out-of-focus shot that I'd normally just delete, but it had some kind of odd sense of space about it that I found somehow appealing, and wondered whether I couldn't use some funky processing to turn the lack of focus into an asset.

I don't know whether I succeeded, but the result is what you see above, something that vaguely reminded me of my memory of some Leroy Neiman Olympic paintings.

I don't use develop presets very often, but I saved the extreme develop [...]

Getting Photos from Lightroom to iPad: a Much Smoother Workflow

Three and a half months ago, after a lot of research and Lightroom plugin development, I published the long writeup "How To Best Export Lightroom Images to an iPad, iPhone, Etc.", about my Lightroom-to-iPad workflow at the time.

It's now completely out of date.

Most everything about my workflow has changed, all of it for the better. It's required months of development, a new Lightroom plugin (Collection Publisher) and major updates to my Crop for iPad plugin, but the result, unlike before, is something smooth and easy.

I'm still looking for the perfect photo-presentation app for my iPad, but [...]
