Third Party Manufacturers / Re: I had a Blowout... On a Hasselblad.
« on: September 03, 2014, 11:20:13 AM »
If this was a car forum, someone would be sure to post, "Oh, that'll buff right out".
So, please tell, aside from the shutter issue, how are you liking MF?
I'm seriously considering a 645Z, wondering how Hassy's implementation of that sensor performs?

The Canon Utility interface is about as rudimentary as the Canon EOS Remote app for Android. Sorry, I've now seen and used DSLR Controller, can't go back to either of those Canon apps....
I have to retract that comparison between the Canon apps. I just tried the PC version of the EOS Utility again after a long time, there is a lot more there than in EOS Remote.
I'm still sticking by DLSR Controller though, it's just pretty much awesomely excellent.

Third, when it comes to live view tethered shooting, you actually need to use the Canon utility for that. LR does not do live view, however it does let you control the camera from the tablet. I like using the Canon utility, as it basically makes your camera more like a view or field camera with large ground glass........
Just as I was posting above, I tried LR + tether for the first time, though my stupid was in action when I couldn't figure out how to switch on live view, d'oh...

I liked DSLR Controller so much on my phones, I bought a tablet primarily to run just that app. Sure I do a few other things on the tablet now that I have it, but I wouldn't have it but for DSLR Controller.

I edit on a pretty powerful desktop with a calibrated, wide gamut monitor, profiled printer/paper/ink and so forth. I've not found anything reasonably comparable and reasonably portable, my sometimes limited imagination prevents me from even considering any comprehensive post processing/editing in the field.
I suppose if I was heading off on a Safari, I'd find an acceptable compromise solution.
Meanwhile, I'm quite satisfied, delighted actually, tethering with a (far less expensive than an SP3) 10" ASUS Android tablet using DSLR Controller.
Chainfire, the DSLR controller developer has released an Alpha build of DSLR Controller AFMA though I've not yet tried it.

Same dev has a WiFi adapter gizmo if you'd like to go that route, some fabrication and assembly required.
There's also Helicon Remote for Android with similar functionality from the same folks that offer Helicon Focus for PC and MAC, I just now see they also offer Helicon Remote for PC and MAC as well as Android.
I'm delighted enough with DSLR Controller that I've not been tempted by Helicon Remote though I'm quite pleased with Helicon Focus for Macro Focus stacking.

edit....... One quirk, maybe it's a 'feature' I've found with DSLR Controller, the program displays an error on connection if you've set to Back Button Focus.
Since so many of my starting settings when tethered differ from my handheld preferences, I've set one of my custom shooting mode settings to full manual, live view with exposure simulation, shutter button controlled focus, works a treat.

I checked the 200-400mm topic in the lens gallery, and something is definitely wrong.  I see nothing at all, so there must be some corruption in the database.  It will have to be rebuilt I think.

I'll let CR guy know about the issue, he has some support people who only take orders for things like that from him.

A post quote from the “Small or Large Thumbnails – Poll” thread......

..... As an aside, am I the only one to see threads with pages which wouldn't load?  I had a look at the "we the photographers" thread and about half the pages only came up blank - no content but no 404 either.......
I found the same on the Cars cars cars (and some bikes) thread.
I tried to back up one page to 15, got a white page. Tried clicking through from page one, got as far as page 10, can't see anything between 11 and 15.

Just now, I went back to the cars/bikes thread, page 11 returns a blank page as does page 15 .

All other pages of that thread load fine.
I as well as others have noticed the same behavior on several threads.

Another site complaint I'd like to air regards the width of the text entry field for quick reply at the bottom of each thread page.
That field is extremely wide, no issue on desktop, most annoying on mobile.
To quantify that width, I just copy/pasted a repeating text string on alternating 'i's and 'w's (narrowest and widest) as …....iwiwiwiwiw....... until a second line began, copy pasted the result from one line into a .doc, word count shows 776 characters wide.
Um, sorry, I'm only able to describe this oddity, I'm at a loss regarding possible causes and/or solutions.

Er, a First World problem for sure, I'm delighted to live in an environment that makes it possible to bother about such things rather than having to continually worry about nut job fanatics, famine, Ebola and other human miseries.

....  The Temporary Internet Cache files on your local hard drive store the image from the first time it loads, then that image file is used repeatedly until it is deleted or it expires from the cache area....
I learned about browser caching in a rather roundabout way many years back in the WIN 95-98 era, Netscape Navigator, I.E. 4 or 5.
I had built a web page of something or other using some WYSIWYG program, the page included an animated gif.
I copied the page and its files to floppy, took it to a friend's for review/critique/show off/whatever, friend was a NN user.
While viewing the page in NN, I happened to notice the floppy kept getting accessed, didn't do this with I.E..
I somehow reasoned that NN was not caching at all, when the gif called for another frame, NN had to go back to the server (the floppy in this case) and download all over again for each and every repeated display of the gif's frames.
In contrast, I.E. accessed and cached the page in it's entirety, once downloaded, it didn't have to go back to the server again.
It may just be that we owe the bandwidth conserving efficiencies of modern browser caching to the snail pace of ancient dial up downloading.

Lenses / Re: Advice: extension tubes Macro
« on: August 20, 2014, 07:57:38 PM »
....Middle East excavation site in progress.......


"An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. For example, adding a 25 mm extension tube to a 50 mm lens will give a magnification gain of 0.5X. Therefore, if the lens's original magnification was 0.15X, then the new magnification will be 0.15X+0.5X=0.65X. The closest focusing distance will also decrease to ~210 mm."

"Note how extension tubes provide minimal magnification when used with telephoto lenses — which is unfortunately their main weakness."
"Closest Focusing Distance
0.99 ft./0.3m (maximum close-up magnification: 1x)
So, a full set of Kenko tubes adding up to 68mm will increase the magnification of your 100L macro only from 1.0 to 1.68.
You'll have a very shallow depth of field which focus stacking can overcome.
To focus stack you'll need a sturdy tripod and either a macro rail or tethered focusing control, or manual focus steps as you determine by eye, preferably in live view.
If you're shooting artifacts in situ rather than on a work bench or table, your tripod will have to be configured to mount the camera very low to the ground such as is possible with an inverted post. Manual focusing with the ground level mounted camera will be awkward and uncomfortable at best, a total failure at the worst.
I suggest tethered control.

If dust can or will be a factor, that may compromise effectiveness and longevity of a focusing rail will all its exposed components, same for a bellows.
I like Helicon Focus for processing the stacked frames.
The Canon MP-E 65mm f/2.8 1-5x Macro Photo lens magnifies between 1X and 5X but must be focused manually which rules it out of tethered focus control is desired. Might be just what you seek if you'll manually focus (and stack) while live viewing tethered.

There's a thread here, "first attempts at macro stacking, let's see some stuff. (beginners only please)"

EOS Bodies / Re: Is this a joke?
« on: August 18, 2014, 07:55:55 PM »
..... it mentions Nikon cameras:
No focus motor
Won't autofocus with all lenses.......

As Nikon has fallen off my radar, I no longer follow specs and details of current market offerings, I've no idea regarding the current state of these things.
- - -
I have, and have worn out both a D70 and a D80.
On the lens mount of these cameras is a screwdriver tip sort of affair connected to an in the camera focusing motor.
Some autofocus lenses of the era did not have their own autofocus motor(s), instead used the camera's built in motor. I have lenses of both types, in lens motors focused significantly faster, camera body focus seemed just as accurate once it finally arrived.
The next generation Nikons one step down in the marketplace omitted the in body focus motors, if a lens was to autofocus, it had to bring its own motors.
There was simply no way for a non-motorized lens to autofocus without camera drive.
Example; had I updated to the D90 generation but a step or two downmarket, my AF Nikkor 50mm 1:1.8D would not be able to autofocus.
In the photo below hot linked from dpreview, see the screwdriver tip looking tab at about 7:00? That's the in camera autofocus drive for lenses without their own motors.

Another downside of this so called 'feature', while this drive is engaged, the focus ring cannot be manually operated, autofocus must be physically disengaged on the camera body, no 'on the fly' manual focus possible.
- - -
I don't know if this is what snapsort was referring to, I looked briefly and did not find. I don't much care either, please, make no effort on my behalf to find and quote whatever passage(s).
I no longer care anything regarding anything and everything Nikon and at this point in my life, hope to maintain that indifference until my end.

Is the 6D a 'pro body'?
Are you implying it's not?
Does Canon Europe consider the 6D to be 'for professionals'?

Note that whether or not Canon considers a body to be 'pro' has no relevance to what photographer uses it.  Plenty of professional photographers use xxD bodies, and I hear there are even some enthusiasts that use a 1D X.  ;)
Irrelevant how the manufacturer or seller classifies a product, it's the consumer who determines its actual use.

Both sides of the coin (the links you posted) work too as you've so eloquently noted, non-pros buy  Canon classified pro bodies with no apparent ill effects, no law suits, no jail time for daring to use pro gear for personal use.
Of course, if one is a corporate shill like the Samsung rep I encountered yesterday, corporate knows best, end users should compliantly and placidly accept corporate edicts with no question.

Only slightly less convenient than a pop up is a 90EX in your pocket, same limited range, same harsh shadows, same optical trigger capability.
I keep one in my kit for those occasions where my photos only need to demonstrate I was there, I saw, verified, recorded and reported. Most of these aren't pretty but they are concisely descriptive.
Most of this work I can shoot without flash, just crank the 6D's ISO up, by the time I've resized down to the clients' 800x533 spec, noise in barely apparent.

Also in my kit is an ST-E3-RT and one or two 600EX-RTs for times when more elaborate lighting is needed, like maybe I want a nice photo rather than a just banal snapshot.
I doubt we'll see radio control built into camera bodies, each market would need its own version according to local regulations.
Terry Richardson is one, so called, pro who's signature style is on camera flash. I suspect a portion of his success and marketability is due to his subjects more than his style.
How he succeeds as a pro is beyond me, even more mysterious than Gursky though I surely don't mean to draw any parallels between the two, their work or their work ethics.

...... loading the same post full of images over and over can be a bind....
I'm not certain on this, perhaps someone more geeky like Rusty will conform or discredit.

As each unique image has it's own unique URL, when a page calls for that unique URL multiple times, it only gets downloaded once using only the bandwidth required for a single download, the browser then locally positions the display of that single copy in multiple locations.
So, if that ^ is correct, there's no bandwidth penalty when displaying the same image multiple times on the same page, the visual clutter issue certainly remains and is often very annoying even on a desktop, much worse when viewing mobile.
Best would be where posters learn how and implement a post/reply method that removes all from the quote that has no relevance to the reply. Being as we are all perfectly flawed humans with widely varied knowledge and experiences, this is not likely to happen.
Hmm, to eliminate visual clutter, let's all learn to post at f1.2, narrow focus and depth of field, clutter be banished to Bokeh.
edit...... visual clutter applies to text that is needlessly quoted, most especially when multi-quoted, visual clutter is not limited to images.
