What do you want to know? How do you do it? What and How gives you the answers!
Of course, there is still a market for full priced stock photos, for those who want the exclusivity of knowing that an image is only licensed to them or has a higher price attached and hence is used less frequently.
One of the only downsides of microstock photo and image is that the images can become ‘common’ with typical stories of companies having posters printed for a trade convention only to arrive and find that three other companies have used exactly the same image on their posters and advertising materials… and its too late to change!
Some would say microstock photography has undervalued professional photographers, but they all said that 10-15 years ago when ‘royalty free’ images took off and ‘ruined’ photographers who were licensing their own portfolios and inflating prices for their photos.
