Why is it that the only person at a wedding who cannot take a picture of the bride feeding the groom the first slice of wedding cake and have the picture on the bride's Facebook page within a few minutes is the same person who is being paid to take pictures?
Because he or she is expected to keep on shooting instead of messing with his or her small camera screen in the attempt to fix a photo and upload it to Facebook? What if doing it he or she misses some other important shot? Other guests are free to ignore what's going on while updating Facebook pages, is the paid photographer allowed to do so?
And, if the paid photographer did try to do that, he or she would need a Rube Goldberg combination of devices, media and interfaces.
Letting aside it's not so complex, what's wrong with that? You're a pro, so you're expected to have the right gear for the task. If you're expected to upload photos as an event evolves, you need the proper personnel and gear to ensure those images are uploaded properly, even if something fails temporarily. Have you see how many people man a cinema camera? Hey, why don't they get away with AF, auto exposure and later fixes on the camera screen?
Photographers should be able to take a picture, review it on the back of their camera, make a few simple adjustments (cropping, exposure, color correction) and hit a "send" button to get that photo to the client or directly to social media or a website.
If you wait for the proper moment to do that, it changes little if you had uploaded them wirelessly to a laptop or whatever and use it for the final steps, which may be also quicker. If you need to do it on camera, it means you're doing it in the wrong moment, and you are just distracted instead of performing what you are being paid for, shooting the event.
The fact that no manufacturer offers that capability today shows just how miserably camera manufacturers have failed their customers.
Will you give a photographer access to your personal pages so you can upload photos for you? Your personal phone may contain credentials for your personal services, what about a "stranger"?
And, if you need a larger screen, it ought to migrate to your iPad or laptop automatically, without having to use cables or complicated interfaces. It should just work.
It's exactly what Canon WiFi adapters do (at an absurd price, I agree). You shoot, and photos are uploaded via FTP. FTP is good, very good. It's a full standard protocol that run across very different devices and networks. It doesn't rely on a single "app" that may work today on a given phone OS, and no longer work tomorrow.
If you like, it's not difficult to have them "professionally" processed automatically as they come in, and upload them then whenever you want. Sure, maybe if you're not an IT expert you need to hire one to help you, why shouldn't you? Today, just you may need to hire a makeup expert, a professional hairdresser, or whatever, for a truly professional work you may also need someone expert in IT.
A colleague of mine did exactly this but the WiFi part (too expensive for him), it shoots mountain bike events, he plugs the CF into its laptop, images are downloaded, automatically processed, and uploaded so events participants can look at them and decided which to buy (unless the organization already paid for them). Meanwhile, he keeps shooting with another card - his camera is not busy while trying to process and upload anything. He wrote the software, I had already told him he should sell it...
That's what Apple understands.
No, Apple understand if it can lock you in in every of its products, it's a lot of money coming.
Think about virtually every breaking news event of the last several years -- the first pictures and video usually comes from an iPhone, not from a professional photojournalist covering the event.
That's just because most people have a smartphone in their pocket, not a pro DSLR. Once they would have had no photo at all, but someone being lucky.
But which pictures have a better chance of becoming "iconic" for an event?
When I go to a press conference
Here, you're right, there's even no need for a pro DSLR to take the usual useless media filler picture that comes from press conferences, a smartphone is usually enough.
