That line no longer exists. If you think about it though, it never really existed at all.
One of the strangest phenomenon is the "purist" photographer. I know that's not what you're advocating, you're talking more "minimalist".
All I'm saying is that if becoming better acquainted with new tools improves your work as an artist, then it's the right choice to make. Assuming you're looking to be a better artist. Anyone who thinks they can't or don't need to be a better artist doesn't really understand the artistic process.
You yourself say it: assuming you're looking to be a better artist. I'm not an artist nor I aim to be one who uses photography as a means to produce artistry. I like making photographs with a camera. And in such case, I do think there's a clear line.
When the camera starts the job and editing just ends it, it's alright with me, as I perfectly assume editing as a neccesary extension of the camera's work (in fact, unless you have a polaroid, you need to continue after the camera to have any photo at all). Now, when the camera just appears at the beginning of a looong process that actually starts at a computer screen, I rather call that image editing.
I just think that being a photographer at this point in time, means being an "image editor" and a "Graphic Artist". It would've always meant that had there been such an easy and accessible way to edit images before the computer.
I completely disagree, I'm afraid. First of all, with the connection between the word "photographer" and the word "artist". Second, with the connection between photographer and edition (understanding edition as a major process that implies a significant transformation of the image taken with the camera).
The reality was it took expensive equipment and chemicals that weren't nearly as easy to experiment with as a computer.
Now the equipment is cheaper, more accessible and the possibilities are limitless.
Again, you yourself say it. Software does not simply substitute a darkroom; it goes far beyond it. With a computer you can do things you could never have even tried at a darkroom. That is already image editing. Part of photography? If you like it so, I won't object, of course! But that doesn't make image editing a part of photography as such; it's just a part of your photos.
I think that something that somehow shows my point is that Photoshop is not really photography software, but Image editing software, which makes that (as it has often been commented here) many of its features go unnoticed and unused by most photographers, as I understand (please, correct me if I'm wrong).
IMO, the best part of digital photography is that you CAN do things that weren't possible with traditional photography and film.
And does not precisely this draw a line between the two?
