In addition to @Pearsonartphoto's excellent answer, there is also the issue of the quality of the Photoshop question being asked. It isn't enough that a Photoshop question be asked, but if the question is one that could easily be answered by looking at the documentation or a tutorial is easily found addressing the question, it is all but guaranteed to be closed, regardless of where the question is being asked.
At the same time, if the question is one of looking to create a specific effect or complete a particular task, one that isn't easily answerable either through the documentation or through one of the myriad tutorials that already exist now, then there is a chance it will remain open and get answered. Please see the FAQ on the main for more information about what is allowed and what isn't.
Photoshop questions are both a hot potato and something that falls through the cracks on SE. Ultimately, this has to do with the fact that Photoshop has so many uses to so many people; it all things to all people, for better and for worse. Photoshop is so deep, that there isn't any one, single place that is appropriate for everything Photoshop. I would be surprised if there wasn't a Photoshop forum in beta now, or trying to reach beta. But, I would question the quality of the answers in that forum since users are already split into their respective groups via the already long-standing forums that exist that also have the ability answer Photoshop questions specific to the target audience and intended usage.
To that end, migration is the answer here. I, as a mod, would rather see a question migrated to the appropriate forum with a change of getting answered, and seeing some getting the help that they need, rather than simply closed. It is not unreasonable to request that a question get flagged for migration elsewhere if an answer can't be gotten in a particular forum. Again, this goes back to the issue of quality, because a bad question is a bad question and won't get answered anywhere.
