By all means capture the essence of the product or service using photos.
Whatever you do, by all means capture the essence of the product or service using photos. Attempt to convey the hoped for meaningfulness to your customers. Show clear and clean reasons for the customers to want to buy what you sell.
Don’t let perfection get in the way of telling your story in photos. Work at reasonably good imagery, but progress. Show what needs to be shown.
Use a current digital camera or camera phone. Work on the setting and the aspect of the shot.
If a professional photographer is affordable by all means get that service. But! Whatever is necessary, move forward with the promotion that’s required. Start simply and affordable; refine and improve when you can.
Sometimes a good snapshot can be more authentic than a highly structured professional effort. Remember: Something is better than nothing.
