Re: Getting work into a Gallery
There are "exhibitions", which are exhibits sponsored by all sorts of arts oriented organizations, and then there are "galleries" which are retail points of sale for paintings of various kinds and styles.
Both are good for getting your work out before the public, for sales and for building your painting reputation.
Most exhibitions have entry fees per painting. That's the way it is.
Galleries on the other hand, take their commission when a painting is sold. I'd be very suspicious of a gallery that charged a fee to accept your work.
This is why legitimate galleries are very particular about the kinds and styles of paintings they accept--they have to make sales to stay in business and they know what their individual reputation is in the art world. If your work fits into their business model they may be interested. If not, walk down the street!
When it comes to galleries, there's one--somewhere--for every painter, but not every gallery is for every painter. Find the ones for you!
