Because photo are more than gear, and just chasing the "perfect gear" could only distract you from actually shooting good photos.

Photography Technique / Re: Why 3:2 aspect ratio?

Hopefully someone can provide a scientific answer.
Maybe there isn't a truly scientific ones. IMHO, in the old days when most photos were made to be sold to be printed on newspapers, magazines and books (or street ads), I guess formats were chosen also for how well the image fit the page frame design with minimal cropping, especially when there was no digital workflow. And the page design was tied to the available paper sizes.

It's also versatile enough if you need to crop it to other formats.

Anyway many other old photo formats were not 3:2. I.e. 6x6, 6x7, 4"x5", 9x12, 18x24... but what was important was the aspect ratio of the final delivered image (which but slides could be different from the "sensor" ratio).

I believe often which format to adopt was a compromise among what could be achieved with available film sizes, lenses, camera body designs (in turn dependeding on the manufacturing processes and materials available) and artistic needs. Also, in the past, not all cameras made rectangular/square images.

Don't know if from a manufacturing perspective there are preferences in building sensors with a given aspect ration compared to another.

EOS Bodies / Re: Canon Looking Into a New Mount System

What's the point of going mirrorless if the telephoto lenses don't shrink in size and weight?

Please explain how they could when the laws of optics dictates lens size and distance for a given image circle, focal length and maximum aperture. Sure, some advance in optics like diffractive lens can help to reduce size and weight - but unless you can change light itself, there isn't much you can do.

A mirrorless camera may be smaller because you can remove the pentaprism, and the mirror, but its lenses size will still be a function of the sensor size.

Sometimes I wonder why Canon and Nikon refuse to make something in the same league as the Otus
Just look at the history of photography and look why Japanese companies were able to overtake the legendary German ones between the fifties and the sixties. Sometimes aiming too high doesn't help to sell enough.
Also, the niche for very expensive products is not usually large enough to sustain many competitors, and entering it may not justify the investment.
How many photographers' customers check each image with specialized instruments to verify if it is the best achievable, or as long as it is 'good enough' for the intended purpose it's ok?

i definitely looked at the d-lites but found some build issue reports with the units and also the trigger for the camera shoe (skyport issue in general). didn't notice a battery option either. i'd rather go with the bowens gemini myself, if in europe.

The units are manufactured in India to keep the price relatively low, but I have no issues with my set. The actual D-Lite RX looks better built than the previous IT model. The stands are also economical models, but they support the units well, and I can also use the with a Manfrotto boom without issues - just added a sandbag.
They come also with the newer Skyport Speed. The good of the Skyport is it's very small and light, the downside is it's run by a button cell, if it's almost depleted it could work erratically, better to keep a spare around because it's not a common type.
The system is also compatible with the USB controller that allows units to be configured from a Windows or OSX PC. There's no portable battery option if you need it, probably not to eat into the Quadra product.
Sure, you can get build a better kit buying separate items, but for a beginner this is a simple comprehensive and versatile solution.

I've never heard of the brand prior to this press release.

Rolls eyes !   Pretty well known in Europe at least - they own B+W too...

I still have my father's Kodak Retinette camera with one of their lenses, and it's a fifty years old camera.

EOS Bodies - For Stills / Re: POLL: What's more important, gps or wifi?
« on: September 19, 2014, 01:51:30 PM »
Bluetooth... LOL!

(this way you could use your smartphone both for GPS and WiFi)

Jokes aside, it all depends on what kind of photos you do more. You may need one, both or none.

And I've yet to see a Canon camera supporting WiFi Enterprise (pre-shared keys are not secure).

i ended up with 1 einstein e640, 1 matthews medium maxi steel kit stand, 1 matthews 10lb. boa bag, 1 buff omni reflector, 1 51" PLM soft silver & diffusion fabric, and the cyber commander with the newer receiver for the e640 chassis. total was around $1050 inclusive.

In Europe, were some US brand may be not available or easy to find, I found a good choice to be the Elinchrom "To Go" sets. For example the DX-Lite RX 4/4 To Go comes with two 400W/s units, stands, 66cm softboxes, one 90° reflector, wireless transmitter (also able to set unit power) and bags to store and carry everything.  Looking around I was able to find it below €800 (RX-One 100W/s and RX-Lite 200W/s units are cheaper), and also Elinchrom offers some cheaper "entry level" kits for softboxes, umbrellas and reflectors/grid.
Anyway, they use the same mount of other Elinchrom products, and compatible ones.
These are good versatile starting kit and not overly expensive,  if one is really interested in studio lighting,  and cover a good range of needs from product/still life to portrait.

A bit of lateral thinking - as you're worried about reflections on the glass, have you tried a polarising filter?
That's not the way you do it most of the times, especially because it may not always be effective. When you can control light, there are far better ways to avoid unwanted reflections.

The biggest thing for me is that I don't like seeing the flash of a speedlite reflect in the bottle. Seems to me like a continuous light would be better suited, but someone had suggested strobes to me.  That's why I was asking.

It doesn't matter if it is a strobe or continuous light, when the camera shoots all it sees a continuos light anyway :) When you read that book, you'll understand why you see the reflection, and how to eliminate it. It depends only on the light source size, subject-light-camera angle, and the type of surface/shape you're lighting.

Not if the light is continuous or not, or the type of source.  This kind of selection is made depending on the subject kind, easy of use, cost, etc. For example flowers and food may not like "hot" continuous light sources. Strobes don't make people shrink pupils and eyes like continuous one may do. While continuous has no recharge times, and let you setup lighting more easily.

If you are really interested in lighting, learn the basics, and everything else will become much easier. Otherwise you will pick up fragmented advices here and there, and you won't know what to trust or not.

I'm looking for a recommendation on a light kit for a beginner.  I want to be able to shoot glass, (bottles, pint glasses, etc) indoors.  I'd like to be able to minimize reflections and glare.

The advice about reading "Light - Science & Magic" is very good. Glass needs the proper technique to be lit effectively - you can do it even with Speedlites, but you need to know where to put them and how to control their lights - and it could be done without spending much.
Once you learn it, you'll know what kind of lighting equipment you really need - and what else you need (i.e. backgrounds)
Strobes or continuous light won't make much difference (although some kind of subjects may be better lit with one or the other) - but especially for a beginner strobes with modeling light or continuous light are very useful to understand what happens.
Some continuous lights are cheaper than strobes, but may not be dimmed easily. Tungsten one may become very hot, fluorescent ones don't (but have other peculiarities), while LED can be still expensive.

Photography Technique / Re: POLL: Do you crop (and why)?
« on: September 11, 2014, 11:57:33 AM »
It's absolutely false pro photographers don't crop. Sure, if you shoot in studio or can frame carefully you usually don't. If you're a photojournalist, you may don't want to crop because of the implied "image manipulation" (but framing itself is also manipulating reality to some extent).

But there are many reason to crop when needed - because the final image requires a different aspect ratio, because you couldn't frame the way you wanted, because the image becomes more expressive.

It was a basic darkroom technique as well. Cropping is just a tool, like a longer lense or different sensor size/aspect ratio. It's non an excuse for being lazy while shooting, but it's not something to avoid at all cost.

Photography Technique / Re: Getting photos home from overseas
« on: September 02, 2014, 05:44:25 PM »
I don't mind the postage - potentially a variety of interesting stamps when I get home - but the adventure of finding a post office could well turn into a chore pretty quickly.
In some countries, even in Europe, mailing an USB stick without using some special expensive services or a courier, it's the best way to 'lose' them. Post offices may not be open all day or weekends.

A local 4G SIM can be fast, but 4G may not be available everywhere, and usually there are monthly or daily limits far below 16GB.
