Just found a couple of Pentax supplied examples from the Q 06 15-45mm lens:

You press the AV/+- button when previewing the JPG.
As long as you don't power off the Q you have the option when playing back the last image too. There's a hint that appears

As soon as you power off, the option to save RAW is gone.

It's a shame they didn't shoot the same scene with the same lens
The closest pair are shots 1 and 5, but shot 1 is K5II with 50-135, while shot 5 is K5IIs with 16-50

That said, the K5IIs certainly does have more bite and detail!

I use pro-grade NAS and it's still too slow for RAW for me. I reckon a Pi running as a NAS is going to be achingly slow!

In the end I switched to an IoMega Firewire-800 drive on the Mac
That's much better

Matt

Compression used in drive backup is lossless. However, it won't compress images, video, or audio very much (if at all). Encrypted files won't compress either.

The other trouble with packing everything into a single compressed storage file is that errors on the drive could potentially make it very difficult to recover everything (i.e. you may lose more than you bargained for).

Copying individual files with a synchronisation tool also allows for quick access to any file or group of files. For example, culling unwanted files is easy when stored as files, but may require twice as much space for a compressed system (e.g. ZIP file compression normally requires that everything be unzipped, and the wanted files rezipped to a new file, and finally the old file removed).

HTH!

BeyondCompare
Lets you do what you want. Have used it for merging changes on three drives before!
Matt

I use external drives and use Scooter Software's BeyondCompare to sync.
In fact I use BeyondCompare for all directory sync, version control and diff operations. Even use it on Mac (with PlayOnMac)

Yes, I found the SMC-F 100/2.8 macro to be a PF demon in backlit settings
Didn't shoot macro that much, and use the DA*50-135 now and that's hardly ever a problem in any setting.
PF isn't such an issue in macro settings

LR4 is now £99, and I think the upgrade is £59 - which isn't bad at all! Unfortunately, I don't have any SMC-F 100mm images to hand to check whether it'll automatically and completely remove PF

Matt

Get a better lens?
PF is a function of lens & sensor, and often a function of aperture too. (My DA*16-50 suffers from transverse CA at apertures wider than f/4)
They do. It's in LR4.1 and Photoshop
(Note it's not in LR4, but only LR4.1)
Actually the CA removal features in LR4.1 I find to be superb (read: the best I've used). If the lens is a profiled one, then axial CA is removed automatically, while transverse CA and blooming is removed with a dropper approach. The DA12-24 and DA*16-50 clean up fantastically and actually increase sharpness - because it's processed at the RAW stage!

The only thing I can say is to Google for different methods that would fit your workflow.

Failing that, work with B&W contra jour

and http://powerretouche.com/Color-fringe_tutorial.html

Matt

Elements or Photoshop:

1. Add a new layer
2. Change layer blend mode from Normal to Colour
3. Pick a soft brush, about the size of the PF, Alt-click to sample colour nearby and paint over

That'll get rid of it
