We do event photography with inkjets and have done so since '05. We started out just printing 8x10's on an Epson R800. It broke while under warranty, rec'd a new printer from Epson, used it for a couple more years. Decided that 11x14's might be an asset, purchased an R1800 and ran the wheels off of it for a few years. Last year we replaced it with an Epson R2000. Great printer.
There are at least two schools of thought regarding event photography. One is high output, smaller prints churned out on a dye sub with little/no postprocessing.
The one that we always subscribed to is pricier, higher quality, multiple images per print (up to 9), custom layout, slower, inkjet prints. Our prints are 8x10's and 11x14's that range from $25 to $65. We can gross $300+/hr with a very good looking glossy or luster product, clear coated and suitable for framing.
Some of you from the US market may smile at those #'s but, trust me, in Canuckistan's sports market that ain't bad.
We will occasionally lose a sale due to the wait but we find most clients are willing to put some time in for a higher end product. I've never seen a dye-sub print that comes close to our inkjet versions in either finish or color accuracy and I don't know of any that will produce an 11x14.
