Lenses / Re: EF 11-24 f/4L USM Specifications
« on: January 30, 2015, 02:42:08 PM »
wider than 16mm due to the way CPL's work.

CPLs don't work with skies only... nor this lens.

EOS-M / Re: EOS M3 24 MP Sensor?

more people are able and willing to buy it.  I hope it comes out just like the rumor.

And some more will be kept away as well. The actual design didn't look very successful. For this class of cameras, low price is not really a driver. It's going to be expensive anyway, especially if you need - and buy - lenses. So keeping the spec down only delivers a camera that is maybe only marginally better than fixed lens one - or even worse (i.e. less compact), while external O/EVF are usually far clumsier to use, and won't attract many users who would buy a camera with a built in one, but not a camera + external VF, and not due to the price.

.....Upgraded to CC.......

In LightRoom is the ability to soft proof for printing, does PS CC offer the same?

In older versions of PS it was under the View menu, "Proof Setup" and "Proof Colors", guess it's still there in CC too, although I don't know if it was moved.

Canon General / Re: Photographer Petitions Canon for Left Handed Camera
« on: January 26, 2015, 11:22:59 AM »
Creating both right-handed and left-handed designs would increase costs a lot (many pieces should be designed, made and assembled for both configurations, and spare parts stored for repairs), and could not be justified by sales.
As in many other fields, designs are fixes (cars, airplanes, keyboards, etc.) and the user needs to adapt, regardless if he or she is left handed or right handed - building devices for both people would be too expensive or would not match rules. For people who can't adapt for disabilities, I too believe some adapter should be made, although they could make the device larger and heavier. After all it's what happens to other devices like cars.
Today fully electronic camera should ease the task, because many commands can go through wires instead of mechanical links, if the proper interface is exposed.
"Modular" cameras could be an option, but they would also be less sturdy due to the mechanical links, and more difficult to make weather sealed.  Costs will increase also.

Interesting how long we will be waiting until Adobe will start using GPU acceleration in LR

One of the reason is that a good slice of LR is written in LUA - a "scripting" language that makes more difficult to use the CUDA (or any other GPU accelerated) libraries, which are mostly designed to be used by sofware written using the C/C++ language. That's why it was simpler to use GPU acceleration in Photoshop than Lightroom. Guess Adobe needs to re-write some of the code to really take advantage of GPU power in LR - just it needs to have a business sense for them, and don't eat into more renumerative PS sales too much.
IMHO LR became a more pro app than it was in the beginning, and needs tu fulfill pro needs PS can't because of the different workflow, but PS is still the "flagship" Adobe app.
I would also like to see an LR that can work with a central repository and database, so more than one station can access the same catalog at the same time without issue...

LR is still very sluggish.
What are your preview settings?

The purpose of the "completely new kernel" is simply to unify Windows PC, Windows Phone and Windows Embedded product families around a common internal core.

This is one of the aims, but not the only one. Remember kernels are also shared with the server version...
This unification had already started with Windows 8 (phones, xbox and PC share the kernel), but was not yet complete.

Just because it's "new" doesn't mean it's improved. Adding code components to support additional product families doesn't inspire hope that it will run better / faster / more efficiently.

Nor it doesn't imply it is not. "New" means also some old legacy code can be removed, and more modern implementation adopted. Every release, even those that were not successful, had interesting new kernel features (if you want to know them, read the "Windows Internals" books)

Exactly.

Wrong. Windows 10 will have new features and improvements as well over the previous OS. Win 8 has features 7 has not, i.e. SMB3, native USB 3.0 support - 7 needs third party drivers -, per monitor High-DPI support, NVMe, Advanced Format HD, and others. 8 also has a different memory manager designed to use less memory.

In 10, expect more native support for the latest hardware standards, more security features, and it will come with the Windows 2012 hypervisor (and probably it will be able to use it to run "sanboxed" applications).

Never judge an OS from the UI changes only. Everything can be released as a "service pack" - even Adobe has no need to release LR6 - it could add the same new features with an update.

From a technical point of view you can always update the previous software in some way. If it makes sense for your commercial business is another thing...

Windows 10 will be out later this year as a free upgrade to windows 7 and 8.  Adobe needs to be working on support for that.
Guess they are working on it, but until Windows 10 is not officially released, LR can't support it officially. AFAIK LR6 will be released before Window 10, thereby it can't support it.

No software vendor I know supports an OS which is still in beta, and not officially released and supported by its vender - and where changes can still be introduced. It's like asking to support the 5D4...

10
I thought LR 5 introduced the requirement for a 64bit OS already, am I missing something here? I was running LR 4 on a work laptop on Windows XP and needed to buy a laptop with a newer OS to run LR 5 to support the raws from my 5D3.

LR5 runs on 32 bit OS but no longer runs on XP. Hope you got a 64 bit OS :)

EOS Bodies / Re: NEW CAMERA - EOS 80D?

It's a fake to bring attention to a device nobody would notice otherwise...  :P

The touchscreen might be important to some, but Canon already has it, and I'd rather skip it because it's one more hardware feature that can break. Plus they made the dial smaller 60d->70d because you are supposed to touch around on the screen and not press buttons as the nearly obsolete old-school photogs.
Actually, touch screen are today cheaper and more durable to make than durable rotary switches and buttons. Also, if you remove holes in the body and all the engineering efforts needed to build buttons and dials, mount and connect them to the rest of electronics, there's a lot of cost savings in molds and assembling.
While from a user perspective well built buttons and dials are far easier to operate and the tactile feedback they provide allows for 'blind use', touchscreen are cheaper because functions can be simply programmed without requiring anything else, context can be changed to allow for different controls on the same area (no ad hoc controls needed, less physical space needed) at the expenses the user can only rely on visual feedback to operate them, and thereby are far slower to use.
I see a trend towards touch devices because it is fashionable and because of the cost savings for the producer, but from an advanced user perspective is a huge step back in usability. I can see some uses just for inputs like the one requiring a keyboard, but not for common photo tasks when keeping focus on the subject is the most important part.

Post Processing / Re: Backup to Blu-ray
« on: January 03, 2015, 01:14:09 PM »
Umm... you're off a bit on the 2.5" drives.  The 2.5" external drives are simply SATA laptop hard drives. 
Nothing more, nothing less.

Exactly. Not designed to last long. Most external drives are built to be cheap. Not to be long term storage devices. Good to shuffle files around, not for long term backups. There are external adapters that let you plug in the disks of your choice. IMHO far better choice than pre-assembled ones where you often don't know what disk is inside, for backups.

Hard drive technology is pretty universal when it comes to the platters and their magnetic retention. 

But construction is not. There are different quality levels. The choice of materials and parts, production line specs and quality controls, etc. etc. After all, are the low end Canon DSLRs and lenses built with the same materials and specs of the high end ones? After all the technology is pretty universal when it comes to CMOS sensors, shutters and lenses... isn't it?

There are drives designed for enterprise level use and durability but in this case we aren't talking about MTBF, we are simply talking about magnetic retention.

But MTBF matters too. Sure, you can use multiple copies to reduce the risk - that's why I always alternate new sets to ensure they don't come near the MTBF together - but disks are more complex devices and thereby with more points of failure.

The quality of the controller and drive electronics/firmware has impact on the "correctness" of data written and its lifespan, as well the quality of the magnetic layer used for recording. Why high-end disks usually come in lower capacities (and longer warranties) than the lower-end ones? Because until they can warrant the same quality, they don't risk to sell you a disk that may fail too soon because the technology is not mature enough.

I spent time for years with a friend that owned a data recovery company

I spend part of my working time with Very Large Database applications running on SANs (Storage Area Networks) made of hundreds of disks (and lately, a lot of flash ones as well). Also the company I work for produces also military spec hardware, which needs to work in far worse conditions. Guess I learnt a couple of things too :)

Anyway, companies like Facebook, Amazon, Google and the like are now faced with the need to store huge archives for decades (of course, unless they go bankrupt earlier) - because users in they early 20s or 30s expect them to store their "memories" for that long - and are experimenting with different technologies to keep data available at least near-line (as users are less likely to access often older contents) cheaply. And Facebook is now experimenting with blue-ray 100GB disks. If you store just the platters, and not whole disks, it's far cheaper.

Some companies (Sony and Panasonic) are working on "optical disks cartridges" able to store 1-1.5 TB each with RAID capabilities Currently Panasonic already offers the ADA cartridges, but they are only 50GB in size, and are somewhat a proprietary format. With the proper recording layer (one which won't decay if a few years, or decades) optical cartridges could become am interesting long-term storage for static data.

2.5" Ext Drives.

These are usually cheap drives designed for laptops, and not designed to last long (you can see it from their actual prices). There are drives designed for long term storage, but it's not those. They may last longer if you connect them just for backups, and then store them properly, but don't expect much. They are cheap, though. Anyway, even magnetic archiving will decay with time (flash memories included).

The quest for the definitive backup media continues.... :)

Vikings first settled on American soil.

For which, unluckily, they didn't left any record able to reach us... bad media backup strategy theirs. Maya ones worked better :)
