I am noticing that I often print my photos about 0.5 to a stop darker than I really should. I would print a test strip, review it under table-top Ott-light and pick a best exposure. Then I would print the full size print and after reviewing it under normal indoor light, I confirm that I'm happy with it. It would even look fine when I pull it from the drier.
In a day or two the time comes to hang it on the wall. I would put is under glass or simply attach to a wall with a sticky tape. And that's when I notice that the print should have been a half or even a whole stop lighter.

Is that an issue with eyes adopted to dimmer light, or is it viewing vertical vs horizontal print?

Did you experience such a thing? What did you do to address it? Please share your technique...

Thank you!
