Flickr Images Published through LR Appear Brighter

I recently started uploading images to Flickr using Lightroom's publish services. I previously just uploaded a jpg. I've noticed that the images published through LR are noticeably brighter than viewed in LR5. Anyone else seeing this.

Are you looking at Flickr on the same device?

Are you using a calibrated monitor and color managed browser?

What space are the rendered images in?

Good point, but they are the same two devices that I've used previously. Upload on an old MacBook and make public after viewing and changing title etc. noticed that they are much brighter on iPhone whereas they weren't before using publish service.

Are you using a calibrated monitor and color managed browser? See above.

What space are the rendered images in?

I don't even know what you're asking in the third question or how that might apply to the publish service.

Showing us a problem image might be a good idea? This might help.
sRGB

Replying again because some of my previous reply was contained in your quote.
Let me first restate my concern because, based on the responses, I'm not quite certain that I explained it well the first time. Up until just a few weeks ago I would export a jpg from LR5 to my macbook hard drive, then upload to flickr. Viewing it on my macbook and iPhone (both previous 4s and current 6 revealed no indications of changes in brightness to the image. Now that I'm exporting and uploading images to flickr from using the LR5 publish service, I've noted that viewing the images appear brighter on my iphone than on the computer. I just uploaded one tonight (flickr link below). The breast of the two snow geese sentries and the water appear much brighter on the iphone than on the computer.

Yes, I'm looking at flickr on the same devices that I've used prior to using LR5's flickr publish service.
I've never calibrated my computer screen. don't know how. don't know what a color managed browser is. Using Safari on El Capitan.

sRGB

The "problem" image is on my iPhone, or rather, now that I'm exporting and uploading images to flickr via LR5's publish service, I've noticed a difference in the brightness of the images viewed on the computer versus viewed on the phone. the phone images are much brighter. Not certain how to show that to you. A link to my flickr is below.

The flickr images look fine to me, but I have no idea where in the chain between LR & phone software the problem can be fixed. Sorry.

My experience with Apple devices is limited to an iPad (my phone is Android operated) so I am probably not the best person to answer your questions, but I imagine that your phone's display is not too different from my iPad (iOS 9.2). The display is not color managed and is presumably somewhat similar to sRGB in gamut although also probably a smaller gamut than sRGB. The one control it does have is a brightness control with which the display can be made brighter or darker manually or will adjust itself automatically (in relation to the ambient light?). So I would suggest that you start by investigating whether something has changed there from what it was previously. Or, alternately, whether your Macbook display has changed.

Also, photos rendered from Raw and uploaded through the Publishing Service are always rendered in sRGB. You cannot choose another space. But when you render and save a photo through the Export dialog, you have to select and set the output space. So what space were you using before? If it was other than sRGB, that might account for the difference that you see today.

Turn down the phone or turn up the monitor?
Yeah, it's a smart ash response, but my point is that different, uncalibrated devices will look different. I've been dealing with calibration for more than a decade, so I don't even think about this issue, but newbies won't know that it's typical for different devices to look different.

Also, when you use LR to send directly to flickr, LR might be imposing changes to how you edited the pic. Check if there are options in that export type that would affect brightness or 'color space'.

There are other approaches you could use to check things out. For example, do the conversions in DPP and compare with the Lightroom conversion before uploading, then upload to Flickr and compare things.

It's entirely possible that your iPhone may be using a brighter display than what could be considered "normal" for us photographers ... this is common with consumer displays. But of course there are other variables.

Also, what happens if you download an image from Flickr that has not been processed and re-sized and you compare in your various displays? Or if you upload to Flickr without using the LR Publish?
