Layers question

I have been using Photoshop regularly now for the last couple of weeks since I re-joined CC and noticed something that seems a bit odd to me. I usually use a workflow tool (Dxo's PhotoLab in my case) as my main tool and send images to PS for specific editing needs. That editing usually involves multiple layers but since I am saving the image back to PhotoLab I typically flatten the image before saving it. If I don't flatten the image I get the layers warning telling me that a layered tiff (which PhotoLab will not process) increases image size.

I also generally add a text layer to the image with the date and location of the image for my wallpaper folder. This morning, after doing only minor edits which did not require layers, I added the text layer, saved the image as a jpg for my wallpaper, dragged the text layer to the trash so there was only the background layer and tried to save the image as a tiff for PhotoLab to handle. I could only see one layer so I did not flatten the image before saving it, but I still got the multiple layer warning.

In looking at the history for the image I see that all I did was open the image, copy the text layer from another open image (taken the same day and place) to this image, save it as a jpg (which, of course, did not require flattening), dragged the text layer to the trash and tried to save it as a tiff. Then I got the message. I then flattened the image and was able to save it without the message, but my question is why did I get the multiple layer message to begin with? I only had the background layer and had copied the text layer to the trash, so why does PS think I have a multiple layer file? Does dragging a layer to the garbage not actually remove it? Or is it something else?

Hi

Is your single layer a standard layer (e.g Layer 0) or a Background layer (with the lock).

The former will generate the message , the latter will not.

This was new information for me, and I guess I still have a lot to learn about Photoshop. It never occurred to me that the name of the layer might change the behavior during a Save As, but your answer corresponds exactly to what I now see when testing.

Thank you for solving that problem. I now only have to figure out how and why the background layer got its name changed to Layer 0, as that was exactly the case.

UPDATE:

I am adding this update to tell what apparently caused the change in layer name from background to layer 0, and thus caused my issue. I expect most users will already know this but I thought this might help those who, like myself, are new to Photoshop.

The layer name changed from Background to Layer 0 when I unlocked the layer. The new layer name, Layer 0, caused the warning message and thus I would not have seen it had I not unlocked the layer. Since there was no need for me to unlock the layer I will not do so in the future unless I have to, and then will try to remember the side effect of doing so.

Hi Mike

It is more than a name.

A background layer is locked and cannot have transparency.

A normal layer starts unlocked (although you can lock it) and it can have transparency

You can convert a normal layer at the bottom of the stack to a background layer using Layer >New >Layer from Background
