Not again,
It sounds as you are just posting to photos sites, and not to an agency or wire service. And there is a major diffference in both of those things. It is DEADLINE.
We know now about Nikon's less than desirable system. My IT person thought it is laughable junk.
How would I shoot three cameras on the fly at a major event, often on the move with other photographers, publicists, security, and the rest with a wired up system? Impossible! The bad word in all of this is tethered, or weak transmission signals of wireless to a computer. No photojournalist would even consider this, even in a press room. That is for studio use, and we have a system for that in my NY/LA grade of studio. As far as having the need to look at your own work, that is because you were never a film photographer, I wager, where editors looked at all the chromes, (Slides for those who don't know), that is the way it was.
But, guess what if you have worked with editors, you will know they don't care about the bad photos which we all take, they understand how hard it is to, come back with good photos from difficult major events. I work on the worldwide level, and some of the things I shoot I have 5 seconds to capture something, so if a few bad looking ones are sent out, it is understood by all editors.
If you are going to work in a creative field, you have to learn not to let that kind of thing worry you. If you can't send the good with the bad in a transmission system, the type I desire, or to just send them all in E-mail or a Dropbox system to an agent or agency, I doubt you are a working professional, not every shot you take will be an award winner. One of the reasons we overshoot things.
If you shoot a major event with people on every continent waiting with deadlines for the images, and want to look thru all your images, well, you can't, deadlines are everything, always have been, always will. If you have the time to dump some, fine that is OK as it saves the editors a little time. However, that is rare for me to have the time to do my own rough edit.
I have met photographers who submit like a dozen images and dump the rest. Thing is they are not really professionals' anyway. Frankly, if you are a journalist, editors will pick the photos you hate the most, so never delete anything being submitted, if you must then do out of focus, exposure problems they would be ok, however, that slows down your transmission time.
I had had the chance to work with some of the best editors in the magazine industry, in LA, New York, Paris and I pass this along to maybe keep others from thinking every professional's shutter release in anyway means each of the photos will be selected as good or useable has no idea how photos, good photos, go from viewfinder to a person seeing it in a magazine, book, internet or whatever medium of quality.
Publishing is a collaborative art, you can't do it all if you want to be a professional and are afraid to have your work judged by editors, you will have all your work suffer, have a loss of creative thinking, over think things and have your work suffer as a result, and won't make the cut. It is very difficult.
Once the the editors select your photo the photoshop artists will take over from there, and go over them, at least for editorial work, and only levels and color for journalism or hard news, as you have to be careful doing anything to news photos.
Hope this helps as we need more good professionals, who are well equipped, and know what they are doing with confidence who can get in there and bring us the world each day. Remember Walter Cronkite's words that 'Photographs can tell a better story than the written word.'
Good Luck,
