When you create layers or masks, Photoshop wants to save as the default Photoshop format. Make sure when you are creating your image its saving the file in the original format, not creating a different file with the same name in a different format. So do a (save as) instead of just save. this way you can see the format its trying to save in. ( another indicator is you should always get the (Are you shore you want to overwrite message when you save).
I'll try to be a bit more clear now that I have been awake a few hours. Image formats like JPG, TIFF and others don't have information like masks or layers. So when you add information outside of the format the original file. Photoshop doesn't want you to loose this information so it default to a PSD file format to save all this layer and mask information. So by doing the "save as" you can save it in the format the original file is. The great thing is Photoshop will do this
converting in it's head so to speak while leaving your project where you were and allowing you to keep changing it.
I will sometime keep my PSD version to, because I might want to edit later or over time. like creating a clothing material then later add a stain or damage over time as shooting. By keeping the PSD version I can return to the layer version and just continue or go back to a previous version. If you flatten or just save the Image file your stuck in the present state and have to edit this version or start over.
In the composer I can launch to External Image Editor (photoshop) and when I do something simple like draw with a brush or adjust Hue/Saturation, when I press Command S it saves automatically and the changes are immediately seen in CTA3. HOWEVER, if I try to do anything more complex, like draw a mask or even insert a shape, when I press Command S it brings me to the save screen and when I save nothing happens in CTA. Please help. Thanks so much!
