Darn. Colin just had to return the thread to serious commentary.
I have spent my entire career in sales and he simply has to be right that the genre that is marketed the most effectively will surely sell the best.
I've never spent a minute marketing my stuff and don't have any immediate plans to do so. If I were going to do that, I would probably begin by approaching interior designers for commercial properties and high-end residential properties. Doing so would probably have the most likely chance of being both personally rewarding and financially successful. I would have no interest in marketing and sales activities requiring anything beyond the minimal amount of time that don't meet both criteria and I'm very fortunate to be able to have such stringent requirements.
I plan to establish a price list for my website tomorrow. I haven't decided on specific markups but I have decided to price prints on the relatively high side considering that my name is
completely unknown. My thinking about that is rooted in the idea that though most people will like my images because they aren't the typical genre seen on the Internet, they will only find them "interesting." Very few people will like the genre enough to seriously consider actually buying a photo. The relatively few that would will probably be willing to pay a relatively high price because they like the genre so much. In summary, if there is any real business opportunity for my photos, it will surely be a relatively low-volume, high-profit margin model, not the other way around.
