Monitor Calibration Inconsistency

[M_Livesey]

For the past few months I have been using Spyder 5 Pro to calibrate my monitor, and re-calibrating it every week or so, always in the same conditions (middle of the day, lights off, door closed, curtains drawn as this is when I edit photos). However, lately I have noticed that when I re-calibrate instead of advising the brightness level to be around 20-25 on the monitor, it is advising around 9-10, which I believe is too dark my monitor conditions. The only thing I can think of that may have changed is the intensity of the sunlight outside, but surely that alone and with curtains drawn can't make such a big difference?

My Flickr username is MattLivesey97 - The photos there were all edited around a month ago before it started advising me to reduce brightness further. I believe that they are at the correct brightness, but would welcome people to feedback.

Thanks

Went to have a look but Flickr says there is no user under the name you posted.

Hi - if you type it straight until Google followed by Flickr it should come up as one of the first links

Your latest ones look a tad dark to me, especially compared to the older ones.

The two cormorant ones are slightly darker but this could be the nature of the black feathers. They don't look dark when zoomed in, and these were PP on the brighter setting. If I drop my brightness level to 10 then they are slightly a tad bit to dark. I'm looking on my moniter which is calibrated using Spyder 5 Pro and the software tells be to set my brigtness to around 25. I always calibrate in the dark with the single light source that I use when editing. The difference to a curtained room between sunlight and a cloudy day can be quite surprising.

Thanks posting the link (the site said I couldn't post a link until I had 3 posts) - If they look too dark on both mine and your monitor's (presumably both calibrated), then I presume I should re calibrate when it is dark and so there is no variability in light. I can only think it may be have been cloudier lately and therefore it recommended lower brightness.

I don't use a Spyder to calibrate , I'm an X-Rite user. However if the 25 setting works well ten don't change it. Also with LED monitors it's not necessary to calibrate that frequently. With normal use once a month or less should be more than sufficient. My old iMac had calibration software installed that allowed you to track calibration of the monitor. It proved to be remarkably stable over several months. I'd suggest a 30 or 60 day period rather than weekly
