If you want to travel in the field and/or have add'l functionality...and have an iPad/iPhone (or soon an ANdroid device), you should look at CamRanger

Lenses / Re: Advice 5d3, wide angle
« on: November 30, 2012, 08:52:45 PM »
Well there are as many or more on this forum alone that don't seem thrilled with the 17-40 on full frame. 

As for the Samyang comment today above, perhaps it has something to do with original version?
http://www.lenstip.com/200.1-Lens_review-Samyang_14_mm_f_2.8_IF_ED_MC_Aspherical-Introduction.html

This wording to start off that review "Important! The review of improved vesion of this lens can be found here"

I'm not real sure how one knows if an older one is slipped in.  But there's some rather high praise from them on the newer good version...  http://www.lenstip.com/239.4-Lens_review-Samyang_14_mm_f_2.8_ED_AS_IF_UMC_Image_resolution.html

Note the different names.....

My wide angle mix, used on the 5D, 5D2, and, now, the 5d3 are:

Canon 16-35 2.8. (considered the II, but not enough difference foe the $s)
Samyang 14 2.8
Sigma 12-24 II
Canon 15 fisheye

None of these are perfect, but they each do what I need in specific situations.

EOS Bodies - For Stills / Re: 5D Mark III Corrupted RAW CR2 files in camera
« on: November 07, 2012, 07:24:47 PM »
My best guess is that it is the card, not the camera.

The only way to find out is to put that card to the side an do not use it.  The use a different card.  If no problems, replace the rad.  If new card has problem, you may have a timing problem in camera.

George Jardine's Library and Develop tutorial are the best and most instructive that I have seen.

BTW...I have looked at the AdobeTv video, have Evening's book, and own and looked at the Luminous
Landscape tutorials.  George's is still, by far, better.

You seem to be aware of the current things to do with 4.1 to reduce processing issues.  If you are having the problems you say, I suspect other issues in your system.  What config and setup do you have?

I've got the same setup LR3 worked with - 4GB w/ 2ghz core2duo & win7x64. Certainly not bleeding edge, but it used to work even with my 800mb 40k pictures catalog. LR4.1 certainly works better than RC2, but it's still useful to restart LR when the lags start appearing after working about 1h+ and rendering a lot of pictures - and a software that needs a restart to work like after 10min is simply buggy. But apart from that, maybe LR4 will never be as fast as LR3 because of the added functionality or because PV2012 is slower to render than PV2010 and/or I'll have to split my catalog into multiple smaller ones.

You get what you pay for, $150 or $99 for a powerfull program like LR will always have issues.

Maybe that's Adobe's way of saying: Apple forced us to lower LR's price, and now see what you've got :-)

Ya know....I started on a 4KB PC with a floppy disk...it worked well...and was FAST.  It was a bit deal when we got a 5MB HD.

What you need to understand is that time changes and, as we want more function, the processing needs and size of programs (and OSs) change...i.e. get bigger and need more power.

I suggest that your processor and memory need to increase.  Adobe said that LR4 would run on it, but...

I would fault them on not describing what was truly needed to get good response time....but I will bet that they were not even sure until the final tuning was done....and I suspect it is not really final, as they got most of the big problems, but will continue to look at ways to tune it.

Pricing is a financial decision...NOT a development decision.  There is not a developer out there who doesn't want to create the best, fastest, most capable program they can....but there are trade offs.  I am glad that

Adobe made the decision to add function to LR.  I would not give up the 2012 processing...it is a major step forward.  A few upgrades are well worth it.

I purchased a new I7 quad core, 3.6GHZ, and loaded 32 GB Crucial Ram.  I have 3 HD's, first is a 560 GB SSD to run programs, 2nd 1TB to hold all cache and catalogs, 3rd 2TB to finalize my photos and storage.  Even with this set-up and when running LR 4.1 it still lags A LOT.........
I think no matter how fast your PC is and try to optimize LR the SLOWNESS and LAG issues will be there until Adobe decides to update the issue with their next realease (4.2 or 3 or 4).  You get what you pay for, $150 or $99 for a powerfull program like LR will always have issues.  My copy of Photoshop CS5 $799 performs so much faster that I can't keep up sometimes. 

My 2 cents!!

I suggest you try putting the RAW Cache and Cat. on the SSD.

BTW for LR, anything more than 8GB is currently overkill, unless you need it for other programs....which may effect your LR performance if resident...depends...

Suggest you move to the final 4.1.  Amazing speed up of sliders response and rendering after adjustment brushes.

It's true that bashing a product based on betas and release candidates is not appropriate. However, even if LR4.1 does show some improvement, the inexplicable slowdowns forcing a restart still happen - to catch up with LR3 stability, I guess we'll have until LR4.3.

I saw a dramatic improvement.  I don't have the fastest system, but I have tried to tune it to LR needs...i.e. fast processor, Win7-64,  >8GB memory, SSD for OS, RAW cache, and LR Cat.

With 4.1RC2, I only had...significant...problems when doing lots of adj. brush work....which did cause, at times, the need to restart as processing time and memory usage increase...a lot.

LR 4.1 final has clear all this up.  I know only see minor delays with LOTS of adj. brush work....no problems with NR on, second monitor active, nor, really, anything else.  Have never needed a restart.

You seem to be aware of the current things to do with 4.1 to reduce processing issues.  If you are having the problems you say, I suspect other issues in your system.  What config and setup do you have?

4.1 RC2 has been the business for me... The speed difference between it and LR 3.6 (but I think there was a problem with 3.6 on my comp) is just incredible. I haven't updated out of it yet, because it goes alright.

The Adobe team did a great job.

Unless speed at the expense of IQ and control is your only priority, jpeg on a DSLR is a pointless option.

I usually put it like this: if you shoot jpeg you start with as much image "information" as you end up with if you shoot Raw and convert the files yourself.

I'll say this too: there's not an in-camera jpeg engine in existence that can process a Raw file as well as I can, and there never will be.

That is simply not true.  The IQ of a good JPEG with a nailed exposure and manual WB is just as good as the IQ of a RAW processed image.  If you don't need as much flexibility in post processing if you are correcting exposure and WB or creative dodging and burning then RAW it is a waste.  You can't use information you don't need.  If you need RAW that is great but it is not going to give you a better image just because it has more information.   

Lesser photographers than you are not able to "nail" exposure and WB 100% of the time....so RAW buys us the ability to recover that "great moment" that might have been lost.

BTW...a "nailed" shot takes almost no time to PP from RAW to JPEG or print.  It just "costs" a little storage and minimum time/effort....but the flexibility for us mortals is invaluable.

I am really not trying to elevate myself as being a superior photographer and saying that everyone who shoots RAW is in somehow incapable of taking great pictures strait out of the camera. I am just saying that it isn't necessarily better and does not create an image with better IQ.  JPEG is not just for speed and ease of storage and it can be just as good as RAW in a lot of circumstances.

I know...didn't mean to make it sound personal, but was trying to make a point.

Essentially, I do not...generally...disagree with you.  However...it....IQ...depends on what you are doing or trying to do.

Most of these are at the "edges"....capturing saturated colors not contained in aRGB, maximizing dynamic range, optimizing exposure to reduce noise in post processing...many more, not worth going through at this time...but available techniques while shooting and in PP.

Basically, if one is happy with jpeg...do it.  I shoot raw.  With Lightroom, if the shots were "nailed" and I just want to go to the web or print out 4x6s, I can just batch them and step away for a few minutes until done.  However, if I want to maximize the output, particularly for larger prints or tight crops...I have the essentials needed.

And, does Photoshop CS6 overwrite CS5 or leave it to be uninstalled later?

No
