Third Party Manufacturers / Re: New Curved Sensor Tech by Sony
« on: April 04, 2014, 04:53:39 AM »
Curved sensors are well proven and effective, been in use at least a few million years.
Took long enough for humans to engineer technology that mimics the retina, eh?
Leads me thinking about beautiful and efficient automotive designs patterned after the aerodynamic shapes of birds and fishes, here's hoping that curved sensors arrive and become refined enough for similar success.
Hmm, will curved sensors allow for shallow depth of field?
How soon before the flat vs curved arguments begin?
Has Ken Rockwell weighed in yet?

#11, Insist a video is 100% CGI when it's creators state that it's not, support that statement with quotes from the creators that state that it's not.

Photography Technique / Re: California Travel Advice
« on: March 31, 2014, 08:15:32 PM »
I lived in CA for 10 years, but I wouldn't know where to begin to answer this. There's just TOO much there.

Unless you're going to be there for six or eight weeks, my best suggestion is to limit your appetite. The distances are great, and if you try to do too much, you'll be frustrated with spending so much time just sitting in a car getting from one place to another.

The landscape/wildlife opportunities are endless and almost everywhere. Do some good planning, again, keeping distances (travel times) in mind.

Yes, pretty much exactly.

California is something like the world's 6th largest economy, geographically larger than most European countries. In some seasons you can drive between sun bathing on the beach to snow skiing in the mountains in just a few hours.

Micro climates abound even within single counties.

Super rich in Beverly Hills and elsewhere, super powerful in Sacramento. Poverty and homelessness  on the streets of most cities.
High crime areas in all the big cities especially Stockton, Oakland, Salinas and L.A., keep to your own business if you wander in to those areas, get to somewhere nicer as quick as you can and you'll be fine, don't linger, especially don't stare. These are not places for tourists to practice street candids.

Busy busy port cities in L.A. and Oakland, huge agricultural vistas in the valleys and along the coast.

Gilroy, the Garlic Capital, Castroville, the Artichoke Capital. There's a brussel sprouts capital too, I forget where.
Watsonville STRAWBERRIES!!!! World renowned and deservedly so. Seasonally availability throughout the U.S. varies. Watsonville also bills itself as Apple City, but I'm originally from Michigan where I learned apples are best following the first frost which Watsonville rarely gets. I'm meh about Watsonville apples.

Incredible beaches all along the coast with about as much variety as everything else. HUGE world class surf at Mavericks near Half Moon Bay, some really great surf photographs come from there. Good surfing along a lot of the Santa Cruz country shoreline, lots of good surf in Southern California too.

Mountains, gorgeous mountains. Really really BIG and old trees in the redwood forests.
Hollywood and the movie/tv industry.
Tesla builds cars.
Silicon valley.
Steinbeck country from Salinas/Monterey through Santa Clara/San Francisco, Jack London country from Santa Clara though Sacramento especially the East Bay (of S.F. Bay).
Gold Mining ghost towns in the Sierras.
Big Sur, Point Reyes.
Hearst Mansion.

Diversity. In my opinion, California's best feature. America's claim as a melting pot exists and is readily apparent daily in many places in California. Every nationality, ethnicity and culture is represented and all get along with each other (mostly) quite well. China Towns, Mexican Towns, Little Saigons and so forth abound. Lots of photo ops here but do use caution, gangs there too.
Great college campuses at U.C. Berkeley, Stanford in Palo Alto, U.C. Santa Cruz and elsewhere.
You can see the Hoover Tower at Stanford from the Campanile at Berkeley and vice versa.
Sweeping ocean vistas at the U.C.S.C. campus.
Epic traffic jams 24/7 around L.A. and beyond, most especially the 405, bring lots of patience, water, fuel and a working cell phone.
The I-280 freeway between San Jose and San Francisco is billed as "the World's Most Beautiful Freeway" to which I'll say maybe, but I figure that's a tough claim to make. It is a pretty drive, far preferable to the 101 for similar destinations. Traffic jams on both ends during commute times, even then, nothing like the usual and continuous jams around L.A..
California Highway 1 along the coast is epic, just epic. A tourist could spend an entire trip just on Highway 1.
San Francisco. I don't know where to start about San Francisco except to say, never call it 'Frisco while there nor anywhere near.
San Francisco is one of those places that I expect will always tug at a piece of my heart (J.J. reference), it is my favorite city, a real stand out.

Public transport is excellent there, preferable to driving and especially parking.
Most tourists wouldn't think of missing the cable cars and for good reason, don't miss them. The restored 1940's era trolley cars are pretty cool, buses go everywhere else, cabs abound.

So many places to go, things to see and do, check http://sfgate.com , the San Francisco Chronicle's web site for events, tons of other on-line resources about S.F. too.
Several, long established camera shops in S.F., but I've never been to any so cannot comment. A lot of hole in the wall electronics shops along Market, I wouldn't shop there but there may well be photo ops there.
I'm only familiar with a few camera shops, all in the "Central" California area.
Keeble & Shuchat in Palo Alto is rather impressive for both size and inventory, I gather it's somewhat like a mini B&H or Adorama in N.Y. but having never been to either of those can't say for sure. Multi floor buildings on both sides of the street, a literal forest of tripods on display in the ground floor main room of the main building. Sadly, staff seems a little rushed though knowledgeable about their products. http://kspphoto.com/
In sleepy little Soquel on the Monterey Bay is the one man show that is the Monterey Bay Photo Mart's Richard. A funky, dusty place with lots of film, chemicals, darkroom stuff and the like, I did buy my (now old) Nikon D80 there on the first day it was released. It's a mix of old and new. If just to buy, best to call first. I'm not seeing a web site, here's a google thing https://www.google.com/#q=monterey%20bay%20photo%20mart&safe=off Richard's speech is a little hard to understand sometimes, he is definitely worth listening to.

Not far away in Capitola and Santa Cruz is the world renowned Bay Photo Lab. Not at all a gear shop, most definitely a top notch photo print shop. http://www.bayphoto.com/
Pardee's in Sacramento http://www.pardeescameras.com/ is pretty much what an old school, local and independent camera store can and should be. Low pressure, friendly and knowledgeable staff, prices vary from fair to competitive.
I do want to give San Jose Camera and Video (in San Jose) a mention, mostly to suggest you google some reviews and that's all I choose to say about that place.

I know you won't ever believe anything I say, maybe you will believe the words of one of the digital artists that was responsible for the actual work, Brenda Busstra-Smink?........

No idea what to believe regarding this production........
Video was presented as from Canon Australia.
Jim Walsh, Leo Burnett are both in Australia.
http://www.behance.net/mrjimwalsh shows this kind of work.
Brenda Busstra-Smink appears to be in The Netherlands, dis-similar work........

Oh dear.

There are no AF tilt lenses.

If you would like to demonstrate to me how somebody in the water could have a cameraman following focus with a tilt lens on a reflection of the eye then you might have a point.

Oh, as for only focus on the eye, try this, go look in a mirror, put a piece of tape on it, stand back ten feet, focus on the tape and take a picture then focus on yourself and take a picture. Notice anything?

It is just CGI, so what?

As for my reading comprehension, that isn't called for. I was pointing out obvious technical issues which you have not addressed.

Ok, you win, tilt shift not needed, just tried some eye selfies (came out horrid), the eye only sees the camera if it's looking at the camera, camera doesn't show in the reflection if the eye is looking elsewhere.
So, never mind mirror shots or tape on a mirror.
- - -
I really dislike being redundantly repetitive again and again.
There is no auto focus in use. Period.
Focus is fixed and on on the eye. Period. If the rest of the face were shown, it would be out of focus.
Reflections in the eye will be in focus.
There is no cameraman, there is no follow focus, camera is head mounted. Period.
I see no reason to think that it had to be CGI, none. It's not Adobe.
It's from Canon, it's about image capture.
 - - -
Try this, in good ambient light, take a close up photo of an eye and focused on that eye looking away from the camera, that eye looking at any randomly detailed scene. Review the reflections, they'll be in focus. Capisce?

Do you find it fun to attempt to overly complicate relatively simple topics?

Try as I could, I could not find a photographic example showing how a tilt-shift lens can be used to get the camera's and operator's reflections out of the image, I did find a few quotes, here are two;

"....If you face a mirror head on, you will be in the shot. If you move to the side, it turns into a parallelogram. With a shift lens mounted, move the camera to the side, turn the film and lens parallel to the mirror, then use shift to get the original composition back (more or less)...."

"....One use for this capability to to be able to shoot straight into a mirror, or mirrored surface such as a glass wall, without seeing the camera's reflection....."
So, my suggestion to use tilt-shift was about removing the camera's reflections, nothing about tilt-shift has anything to do with auto focus or anything else in the composition.
Does that help you with your reading comprehension?
- - -
.....Get real. How do you take this panned and auto AF'd in the water shot with a tilt shift? It is CGI. As is the meteor shot, which castes doubt on most, if not all, the others.

Ok, here's real,
(attachment should be here, don't see it in preview)

SOC jpg shot handheld on a 10mpx Nikon D80, iso 100, 1/125, f6.7, 300mm (x1.5 crop = 450mm), cheap arse Tamron 28-300 zoom, image tightly cropped, then zoomed to ~240%
Consider everything going against IQ, sharpness, depth of field etc., in the image.
In this image are a primary subject, the model's eye, and the secondary subjects, the reflections.
Depth of field in the primary subject is thin, in the original, the eye and most of the eyelashes are in focus, the eyebrow is quite blurred.
In the secondary, reflected in the curved surface of the eyeball image, the photographer, cars, buildings and horizon are readily apparent. With currently available, top level gear, IQ and clarity will be much greater than what is shown here.
Your auto focus concerns are irrelevant, camera/lens only has to focus on the eye, whatever is reflected in the eye will be in focus.
- - -
The skydiving sequence (00:16) gave me the most trouble imagining how it was done, then I realized the camera was helmet mounted, pre-focused on the eye, whatever the eye looked at ended up in the shot. Likely many takes were required. Wind buffeted the camera on its mount.
At 00:10 there's a hex reflected, no, that's not reflection of aperture blades, it's an umbrella.
At 00:20 following the skydive is a boxer. Notice light changing, flashes popping in the background.
There is a handheld look to most of the sequences, there is motion apparent, camera relative to eye. The sequences could not have been shot handheld, I am quite at a loss to imagine how the handheld look was achieved.
Meteor sequence? Same as the rest, whatever reflects in the eye is captured as the secondary subject. The primary subject must only look towards the desired secondary. Camera follows the primary eye, eye follows the secondary.

Schedule the meteor shoot same as any meteor shoot, google it.
Likely several simultaneous takes using multiple models and gear set ups.
- - -
Panning? Primary subject's head with camera rig pan together, eye stays in focus, reflections stay in focus, done.
- - -
Here's hoping your clients don't suffer from your lack of creative imagination that your post here has shown.
I quite enjoyed this video for it's artistic and entertainment value, that enjoyment has decreased significantly through this technical dis-assembly.
- - -
I'll concede only a maybe regarding the meteor trails, and that concession concerns only light levels as I've never attempted anything similar.
Kudos to those that did even if CGI was involved.

I continue to doubt that Canon would resort to CGI to promote imaging gear, this was not an Adobe, fake what you can't do for real, production.

........Though when you look at the angle of reflection and there is no camera there you can be pretty sure that at the least it has been retouched, the video has many shots where there should be a camera reflection and there is nothing.
The series could have been planned with that in mind from the beginning, then shot with a tilt-shift to keep the camera and its operator out of the reflections.
Might have been all CGI'd, might have been well planned and executed primarily in camera.
I like it a lot, I'd like it even more if I knew it was great camera work and not CGI.
On further reflection, why would our beloved Canon, the long standing dominator of the pro imaging market resort to CGI in a corporate production?
They make and sell the gear that makes such a production possible, surely they also have access to the talent and experience to execute.

When are people going to learn it's the 12 inches behind the camera and NOT THE CAMERA.
About the same time they learn that there's no difference in driving experience between a Prius and a Boxster.
You can play the same chords, the same song on a Rogue RA-090 as on a Martin 15 Series. Which would you rather listen to?
I doubt that Ansel Adams meant that statement to compare results with a Pinhole or Brownie Box camera to those with with a view camera, a Hasselblad or even a Polaroid.
There's a huge difference in the effectiveness of the 12" behind if that 12" is inside the car shooting through windows or on a platform on top of the car with a tripod.
Gear does matter. More expensive gear matters more.
Good gear used well satisfies the artist and the viewer.

“......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.......”
Since depth of field is so extremely shallow, to get the most of your subject in focus, get your plane of interest as close to parallel to the camera's sensor as possible, um, same as right angle to the lens axis.


EOS Bodies - For Stills / Re: 6d Banding/Posterization in Blue Sky

1) In the 6D's menus, bottom of the third page from left is Color space. Select Adobe RGB. You'll get the most pleasing results if the gamut of your monitor and workflow software also display in Adobe RGB or wider.
2) Those don't look like dust spots to me but dried liquid residue.
Dust spots are usually well defined with hard edges, dried liquid residue spots are soft like the ones shown in your photo above.
I find sensor cleaning tense and tedious, one of my least favorite photographer's tasks. I've also accepted that it's necessary and too expensive to farm out.
It's not really very hard, clean, check, clean, check, repeat until satisfied.
I use a couple of tools.

Tripod, should be self explanatory, holds the camera while you work on it.

A $12 USD hand pumped garden plant sprayer from Walmart for my pressurized air source.
Canned air has propellants, some propellants are detrimental to the task, they're expensive.
I find squeeze bulbs wimpy.
The plant sprayer when fully pumped has good burst volume at low pressure.
Since someone here is likely to jump on that low pressure statement, I just measured 25.5 PSI deadhead pressure. Spray pressure past the diffuser must be much lower. Still, back away from the closed shutter blades while spraying.
As soon as I've depleted the compressed air, I pump again so it's ready for next use.
For wet cleaning, I use Sensor Swab swabs, Eclipse solution.
I have the EG-S focusing screen, I use the included tool to remove the screen.
I lock up the mirror, remove the lens, blow out the mirror box with the shutter closed and sensor not visible.
I remove the focusing screen, blow out the area between the screen and the bottom of the prism, re-install the screen.
I clean the mirror box area first so as the (hopefully) remove any hidden dust bunnies from that area prior to exposing the sensor for cleaning, don't want those bunnies able to get to the sensor.

Now I enter the Sensor cleaning> Manual mode which opens and holds the shutter, exposing the sensor, blow it off.
I stop and take a test shot, stopped all the way down in AV, ISO 100, focus at infinity. I'll shoot plain paper or notepad in full screen, view the shot in full size on the PC, scrolling around looking for problem spots.

If there's anything left after dry cleaning, it's wet clean time.
No more than two or three drops of solution on the swab is needed or desired. Full strokes from one side to the other, swab makers insist only one pass should be made with each side of the swab, I always exceed that recommendation.
This is the part I find nerve wracking even though I've never caused myself additional issues.
Quick quick as you can after swabbing. air blow the sensor.
Check and repeat. And repeat. Repetition until satisfied is the tedious part.
My most recent cleaning job left one small dried wet spot, barely visible at f22, couldn't see it at f11 so I left it.
FWIW, my 6D, brand new in the camera store had dust visible on the camera's screen, icky. Fact of life I suppose, no sense complaining, just deal with it.


There's a girl in the photo?  I guess I was too busy looking at the old hand riveting ;)
Cue Frank Drebin;
"Nice Rivets!"
"Thanks, just had them hand hammered!"

I wonder if that means individual lens AFMA values will be deleted by the firmware update?
That's how I read it.
