One of the greatest strengths of this site is the easy-to-use, robust database. And a key part of the database is the photos that members submit to it. And there are a lot of talented, technically adept photographers on this site.
Last year, Dave created a Photography Forum in which people share general photography tips, offer advice on how to shoot plants and flowers, and answer questions that other members have. Over the winter it's gone a little dormant (art (creators) imitating life??), but there are a number of good, general threads there that are worth reading...and I expect the participation to increase as the weather warms across the country.
While there are scores of fantastic sites dedicated to photography on the web, this photography forum occupies a unique place in that space because its focus is on shooting things garden related. So...I encourage you to have a look if you've not visited that forum yet. And if you have the time and inclination, please take some time to share what you know about photographing the subjects that we love on this site. Or, if you have questions about some aspect of photography, ask them there. Lots of people there are willing to help site members figure out how to take better shots.
The Photography Forum is a great resource on this site, so please visit it (and contribute to it if you are able).
