I am a professional designer. I'm only a very part-time photographer
So you are not part of the target audience for Lightroom.
So what you're saying is, we should all just suck it up because Adobe is leveraging their partial monopoly to force us all into a model that we don't really want?
No, I said that the target audience will have no big issue with paying that kind of money for this software, while the rest is complaining about the price of a software that they don't need. Or at least I don't get what a part time photographer wants with Lightroom on the iPad.
Reminds me of all those people who complain about how unbelievably expensive Adobe Photoshop CS is, when Photoshop Elements or gimp would be enough for them, while the people who actually need and use the advanced features have no problem with the pricing scheme of Photoshop CS, just as you said yourself.
And yes, subscription schemes suck, but the vast majority of professionals have usually bought every Adobe upgrade anyway.
Adobe is not stupid. Yes, their software is expensive, but the price is usually what they know the target audience will pay. Sure, they could lower the price from $99 by $50. then perhaps 10% more people will buy the software, but the profit dropped by $50 per license sold. How exactly would Adobe benefit from that?
Well good luck to you my friend.
I don't need luck here, as I am not part of the target audience either. When I do RAW develoment, I do it at home, with a good calibrated monitor.
Personally, I believe in the power of the consumer to vote with their dollar, and I'm doing just that (in addition to voicing my frustration occasionally in forums like this).
Of course, the consumer has the power to vote like that. And that is what is happening: Adobe is making lots of money with their software. They are making it from people who either need the software to do their job or who are so enthusiastic about their hobby that the fee paid to Adobe is just a minor item in their annual budget. In fact, compared to what enthusiasts and professionals used to pay for film in pre-digital times, $99 is nothing. That's what Adobe knows and these are the people who they are targeting.
I really wonder what the people who want Lightroom for $4.99 actually believe they would need it for. "Oooh, I just took this RAW image, I really need to develop it RIGHT NOW on the iPad, because the JPEG my camera produced simultaneously is not good enough for Facebook!"

And Pixelmator is an excellent product that does everything I used to do on my cracked version of Photoshop, but I didn't pirate that Pixelmator, I bought it because it cost me 20, which is a great price; again, single shot...
And this is actually exactly proving my point: People want a pro software with pro features they will never use, and then they complain that they can't get that pro software for some ridiculously low price. At least there are people who realize at some point that there is cheap non-pro software that does everything they need.
If everyone who has a cracked Photoshop CS version on their hard drive instead downloaded gimp and donated $10 to the developers, then perhaps gimp would already be much closer to Photoshop CS in terms of features and quality.
