Hello all. I've re-built my desktop computer and I now need to figure out a consistent way of preparing my images for posting here – via FlickR. So Please can I ask you to take a look at this standard test image and report how you see the results at your end. Please comment thus:- Maximum black – the darkest square you can distinguish at the bottom left. Maximum white – the lightest square you can distinguish at the bottom right. Any banding – in the black to white ramp. Any gross artifacts – colour cast, skin tones wrong, too dull, too bright, whatever. Many thanks. Ps – for the record – my results. Original file. 14 253 no banding – ramp symmetrical A tiny bit dull – kinda “safe looking” jpeg prior to posting. 14 253 no banding – but ramp shifted to dark end a bit. About right – a little more saturated than the original. As seen here - by me 20 253 no banding – ramp symmetrical Bright and cheerful ! - a bit bright and a little over saturated.  |

Now as I use a duel monitor set up, I view the internet on my second uncalibrated (as yet) screen which I also use for the tools in Photoshop, this screen is a lot brighter as the blacks can be seen as low as 10 and all the whites look the same. But when I move Chrome over to my calibrated screen I get the same results as your last 'As seen here - by me'.

Hello, Nick. Here is how I view the test image on my setup:
As seen here - by me
2 is very faint but still noticeable. 4 is the one I can easily distinguish on my screen.
253 is very faint but still noticeable. 252 is the one I can easily distinguish on my screen.
no banding – ramp seems to have a 20% black to 80% white ratio on the gradient.
When I viewed this without using any ambient light, it is bright and contrasty. However, when I turned on my room's ambient light (3 CFL lights) it looks just fine with me. Not too bright, not too contrasty. The skin tones are also very good when viewed.
I am using a DELL 16:9 screen and my browser is Firefox. My monitor is not technically calibrated using any tool. I only calibrated it using online test images using my poor old eyes. Hope this helps.

I noticed that, too Steve when working with images. The ambient light does affect how we view images on our monitor screen. 4 days to go before Christmas! Hope your family will enjoy the season together and with love. Cheers, Steve. |

Barry, Steve, jiro, Thanks for taking the time to give feedback. Fascinating results – especially on the max black.
All – please, if you can – take part in the exercise. The wider the variety of people and set-ups we get data from the better we will all be able to understand issues around presentation of our images. In other words – since this is a standard test image the results should be helpful to all of us. When I get the production process nailed I will let you know all about it. Thanks.
… and on the laptop I've been using for the last six months – in typical lighting conditions – the results are
18,
252
no banding – but ramp shifted to the light end a bit
A bit bright – a little too saturated – with a hint of a magenta cast in the flesh tones.

This is a problem I use to come across when giving illustrated talks using various club projectors, they all seem to be different brightnesses so I brought my own projector now so that I can control how my images are displayed.

Thanks George.
All, please keep the results coming.
So far the process is simple. In LR v3.6 I select my finalized image (post photoshop) and use the LR Export function with the Web preset. The preset has size set to 800px on the long side. Sharpen for screen - standard. Output is sRGB jpeg with max quality and then shipped to FlickR.

6, 248, no banding and symmetrical.
All images nice and bright. Yellows look a bit oversatturated and flesh tones slightly warm.
Viewed in Firefox on a 17" gloss laptop monitor.
