What sort of carry-around cameras do the professional photographers carry around with them?

What sort of camera do you use?

Are there any that are, such as Nikon or Canon top-of-the-line cameras, a pretty standard choice among this group of people?

August 4, 2014

Could any of you recommend a slick compact camera, light and thin, that produces very good or excellent images? I'm looking for a nicely designed one that is handy to carry around all the time, but which also takes great pictures. The manufacturer is not important.

July 31, 2014

I'm interested in doing the kind of photography you find in gardening, architecture and décor, and lifestyle magazines, such as Germany's Wohnen und Garten, Landhaus, France's Art & Décoration, Italy's Grazia Casa, Casa Facile, Marie Claire Maison, Ville e Giardini, USA's Town & Country, Elle Decor, Architectural Digest, UK's Elle Decoration, Islands, Traveller, but also in magazines such as Vanity Fair and Tatler and Géo in France.

Is this all lifestyle photography? That is the name of the subdiscipline?

Or is it all different: architectural interiors photography, gardening photography, landscape photography (Islands)?

Are there any famous photographers in these fields whose portfolios I could see online?

And some tips on how to do this kind of photography.

June 22, 2014

Could some of you tell me how does sports photography work?

I would like to know about the equipment, cameras, lenses, and anything else special that helps the process, the exposure settings, and how is it that the images almost instantaneously get uploaded on a server and into an online image gallery for one of the photographic agencies? Do the photographers use the flashes?

Watching the FIFA World Cup, I've noticed that there is a whole bunch of cameras behind the goals. Does anyone know what is their special purpose and how are they operated remotely?

Are there any tricks, such as the so-called trap focus, which are regularly used in this field?

January 13, 2014

Thank you, Stephen Lewis and David Bebbington!

That is the answer I was looking for. I have no idea why people are so evil and why they roll their eyes when I haven't said anywhere that I was going to buy any of the things I was talking about.

Simply, after days of Googling and reading about these systems it seemed to me that there was always something presupposed, implied, which, obviously, is normal for people who do this every day, but if you are starting to delve into the matter, a lot is unclear.

So Stephen's definition of precision spacer is what I was aiming for – I just didn't get why they call it a camera body when there is no sensor in it. If it is just a spacer, why is it so expensive? I am talking about the Alpa, for example. What exactly do you space with it?

I presume if you have a Master Technika, or some other similar technical cameras, what you get when you by it is the front standard, the bellows, the rear standard and the film holder / ground glass. I just didn't understand what is the purpose of Alpa's 'board', that black thing, or wood-coloured thing, that has a hand grip attached to it.

I have just descovered Cineflex, and I love it.

So far, I've managed to find that it was used from Hollywood films, such as those about James Bond, television series to reality shows like Survivor, The Real Housewives of..., BBC's The Apprentice, and so many more, and news coverages of events such as the royal wedding or any current news report needing aerial imagery.

One station in Oklahoma has a Bell helicopter with a FLIR system.

However, I haven't managed to find anything about FLIR UltraMedia HD on FLIR's website.

What other superHD systems are out there? How much do these systems cost? I bumped onto $400,000 cost of a Cineflex, but I have no clue how accurate it is.

I should add that I carry an <a href="http://www.acrartex.com/products/catalog/personal-locator-beacons/resqlink-plb/" rel="nofollow" target="_blank">ACR ResQLink</a> now, too-- I'm not getting any younger.

Cameron Davidson (www-camerondavidson.com) used to carry a ACR MicroFix PLB-406 MHz PLB with GPS with him a few years ago, that's what he said in an interview, perhaps he now uses a newer model.

Dinora: The issue with using the GPS for altitude, is that there may not be a clear view of 4 satellites. You need the forth for altitude and only three for location coordinates. You're right that weather effects the pressure and therefore the altitude reading. But you can calibrate it to either the GPS height while you are in a clear area. Or you can put in the actual altitudeif you know what it is. SUch as a previous determination of what altitude your home is. You set that before you leave. Or, looking a a topo map and then seetting it to the location you are currently at. The pressure port reading will adjust to the local barametric value. One other advantage of the pressure reading over the GPS calculation, is that some people use it as a barametric instrument that you can see a plot over time showing not only the elevation track, but also barametric for change of weather. Handy if you're up in the mountains and where are quick changes in weather.

The Garmin 30 also comes with an three-point compass in addition to the pressure sensor. The advantage is that you can determine direction from a stand still like any other compass. Units like the Garmin 20 use your moving from one location to another to determine compass headings based on changes from the GPS satellites. GPS systems cannot determine direction your facing, only location at some spot in the world. That can be confusing to a GPS especially if you're on a boat or frankly just standing there.

If you have the money, go for the 30 or something similar.

Oh, I see. That makes it much clearer. It was a bit of a discovery that an altimeter shows a more accurate reading than a GPS using the satellite technology.

There are many Internet resources describing the problem, and it usually begins with the question "What is sea level" when the earth approximates an ellipse and there are vast landmass areas where no ocean exists while ocean levels are affected daily by the moon's gravity. GPS systems use the <a href="https://www.google.ca/search?q=WGS+84&espv=210&es_sm=122&source=lnms&tbm=isch&sa=X&ei=2hGUUv_ZE_GCyAGJ74CwBQ&ved=0CAkQ_AUoAQ&biw=1440&bih=769#facrc=_&imgdii=_&imgrc=xpvW7fMAkEpyPM%3A%3BLxrAZ4hzH9950M%3Bhttp%253A%252F%252Fwww.pha.jhu.edu%252F%7Ehanish%252Fww15mgh2.gif%3Bhttp%253A%252F%252Fwww.pha.jhu.edu%252F%7Ehanish%252Fseminarmain.html%3B1025%3B636" rel="nofollow" target="_blank">earth's gravitational map</a> to determine relative altitude based on the World Geodetic System, WGS 84: <a href="http://en.wikipedia.org/wiki/World_Geodetic_System" rel="nofollow" target="_blank">http://en.wikipedia.org/wiki/World_Geodetic_System</a> The problem of absolute altitude measurement is further compounded by satellite location and a particular receiver's susceptibility to multipath signals which can dramatically increase measurement error. Geodisists typically use professional grade GPS units to minimize various contributors to cumulative errors which can cost many thousands of dollars. I've all but given up on altitude measurement when I tried to obtain a meaningful GPS reading while setting up a TV antenna relative to the stated transmitter altitude about 100 miles away. For recreational use, however, typical consumer grade GPS are probably more than adequate for relative measurements on personal travels.

I actually presumed that there were many descriptions, but I didn't know which one to type into a search engine's box. I did find that

Calculation and mapping tolerances are much smaller wherein achieving near-perfect closures are desired.

</blockquote>

What exactly are closures? It's a bit tricky to connect it to the mathematical concept of a closed set.

It is from a kit lens, shot at 45 mm:

November 25, 2013

Oops!

Global Positioning System (GPS) receivers can also determine altitude by trilateration with four or more satellites. In aircraft, altitude determined using autonomous GPS is not precise or accurate enough to supersede the pressure altimeter without using some method of augmentation. In hiking and climbing, it is not uncommon to find that the altitude measured by GPS is off by as much as a thousand meters,[citation needed] if all the available satellites happen to be close to the horizon.

</blockquote>

How do the geodesist determine the elevation of a point?

November 25, 2013

Thank you, everyone, great replies!

I am struck that even though I've used the navigation app in my phone (and hated it), I never thought that there could be a GPS app somewhere out there. But – d'oh.

However, yes, I would need a stand-alone, handheld device. So I'm checking some of the mentioned Garmin devices and they all have a barometer altimeter.

Why on earth is that? I thought it would be easy for the satellite also to provide the altitude information, but it seems it isn't so. Why rely on a barometer? It's kind of tricky, given that pressure is dependent on the lapse rate, and the lapse rate on humidity and some other factors, to calculate it that way. On the other hand, I guess these people should know what they're doing and it should be fairly precise.

I wonder if I could find the accuracy information in some Garmin brochure or something like that, the detailed technical specification.

November 24, 2013

Can anybody tell me where could I find a GPS unit that I can carry in my pocket, which will show me the geographical coördinates, altitude above mean sea level and which is very precise, showing me the coördinates in decimal angular secondr?

Does, for example, Garmin have one?

Or any other manufacturer?

October 11, 2013

Does anybody know a website from where to buy a new Pentax 67II?

It doesn't have to be a U.S. one.

I couldn't manage to find any information about the camera on the U.S. version of the Ricoh Imaging website.

Does anybody know who shot the Pentecost River on Kimberley Plateau used as a wallpaper from the Australia theme in Windows 7?

October 9, 2013

Thank you, Jeff!

I love those two websites!

And thank you, JDM von Weinberg. I know how to use Google. My Google fu skills are mind-blowing. You could've simply sent me to http://www.lmgtfy.com/

The point was that people here already know specific, particular photographers whose portfolios are well-known to them and they admire it and I wanted them to share their imagery.

October 8, 2013

Are there any photographers who shoot with large-format cameras whose websites, portfolios, galleries, images and books, including the members of this forum, can be found online?

October 8, 2013

Are there any photographers who shoot with medium-format cameras whose websites, portfolios, galleries, images and books, including the members of this forum, can be found online?

October 4, 2013

Does anybody recognize this particulat type of tripod?

August 13, 2013

It says nothing.

I want to ask something about white balance and altitude in the GPS data: if it says both manual and cloudy, is it manual or cloudy? Preset or really manually set, but in the range of cloudy? The GPS altitude is the altitude above mean sea level?

Does Jeffrey's Exif Viewer keep the images on his server or only temporarily and deletes them?

August 12, 2013

I was using FastPictureViewer and it just says "Dst".

August 12, 2013

I am looking at some EXIF data and I see something like

1/100, f/5.6, ISO 100, +0.3 EV.

</blockquote>

So what I'm wondering is if I'm in aperture mode, then the camera adjusted either the shutter speed or the ISO. Which one did it change? And is what is written in EXIF what is the final version of parameters or are the values the uncorrected ones?

Another question is about the parameter of distance, which some files have. One shows 11.9 m, the other -1.0 m. What does it tell? How do you focus on 11.9 m or -1.0 m? I presume the last one is hyperfocal distance, but the first one baffles me.

August 10, 2013

Could somebody explain?

I was looking at the Alpa TC and I don't really get it what it's about. Basically this is just 'something', I don't know what term to use, you attach a lens to (OK, d'oh, that's the standar part), but then this thing actually doesn't have a sensor. If you have to attach either a film back or a digital back, then what is it? What exactly is a film back and who produces them? What does an Alpa TC do?

Then I'd also like to know what a technical camera is.

And what is a view camera.

And is it possible to learn to use all three and can you do it via a manual or is there a better way?

Regarding the Hy6, I stumble upon this

The good news is that if and when either Kodak or Dalsa is able to manufacture an affordable 56X56mm sensor, the Hy6 will be able to take a back that size. The lenses already cover that format. In fact when shooting 645 one is using the "sweet spot" of these already superb lenses.

</blockquote>

So what kind of a back will Kodak or Dalsa manufacture? (This is an old article so they probably produced it already.) What are the lenses which cover it. I'm confused about the last line: so what? How will the soft spot situation change when there is a 56 x 56 mm back? Am I not using whichever aperture I'd like to use with these lens? And aren't they much sharper than any 35 mm lens making the sweet spot concept not unusable, but somewhat irrelevant?

I'd like to know the point of the line, what does it mean and why is it relevant.
