I like taking photos with my iPhone 6. The results are almost always acceptable. Some of the newer phones are even better, but the iPhone 6 and that generation of devices have hit a point were I feel the results are well within reason for promotion of products and services in small business.
If there is a bigger budget for photography it might be better applied to the distribution efforts for the message that is being conveyed. That budget is almost always an issue.
Certainly there are exceptions to this thought. I just can’t conceive of the situation though, for a small business on a small budget, where that would apply. Perhaps if the business owner is a photo buff. Someone that has the equipment and the inclination for a more perfect outcome artistically. Remember though that higher density digital photos require more to store and more time to load on line. So tradeoffs are required for real professional grade photos. Expertise is another matter. A good photographer can made any shot better by considering lighting and the set up for the shot.
What we’re trying to achieve is familiarity and positive empathy toward the business. Decent photos that tell the story are among the tools needed – they aren’t the goal.
