Images from Hospital visit...for C&C

I too was fascinated by the abrupt change of shade inside of the tubing loop. Especially as it follows the path of the tube!

So, I took the liberty of downloading the image and using a tool or two on it. This one certainly tells the tale:



And here's how RawTherapee sees inside and out:



Of interest is the Lab numbers below the histograms showing the difference in lightness of course but also a slight shift in hue if read a* and b* correctly.

No idea of the cause, though . . .

Thanks Bruce...I learn something each day...I was just confused as to why his colour management says that I am using AdobeRGB when all my settings indicated I am not hence my comment because I am confused...My colour setting in PCS6 is actually SRGB. I captured my Colour Settings from Photoshop...here it is...



Do you think I should change the first option to Monitor Screen instead??

Izzie, I'm not certain whether Mike's tentative explanation is correct. It may well be. In response to your question, I don't know in what circumstances you'd ever want to choose "Monitor Screen". My guess is you should leave the settings as they are unless someone like Manfred or a CS6 guru suggests otherwise.
When I'm preparing an image in CS6 that's going to be used on the internet, I save a special copy of it and deliberately change the colour space of that copy to sRGB. There may well be simpler ways of doing it that I don't know about. If I'm dealing with an image where I've been able to do all the editing in Lightroom, the process is easier since I use an export preset.

What a long thread! Sorry for posting a bit late Isabel . I just want to say that I wish the best for Bill I don't want to comment on the images as hospitals don't remind me nice things.

I understand Binnur...I don't like hospitals either that is why I keep healthy...hate doctors, hate taking pills and I don't like needles poked at me...one day I might need them but not yet...

Bill is doing very well, but his pain medication is a little bit too strong I think and his memory is not like last week's. I will bring him back this coming Wednesday for those stitches to be removed. I have not heard this one before but men can also have lumps on their breast...therefore if that wasn't removed, he would have had cancer or something...strange, but I thought only women have breast cancer...thank you for passing by. I appreciate it very much...

Grahame, I must apologize to you for thinking that the walls here you uploaded is almost pure white. When I looked at it again last night at my desktop and that big screen, the colours of the wall is very right exactly as I saw it...when I commented I was in my laptop...I should stop doing this...I need to go upstairs if I am going to CiC...sorry again...

Thanks for the explanation Izzie of how you reached your result with the WB on No 1. It's one of those scenes that's not straightforward due to the lighting and in reality if its just a snap more than likely not worth spending much time on. Even just moving around with the WB picker in ACR there's so many 'slightly' different results from white and grey surfaces the best one is what pleases you

I'm still baffled by what has caused the difference in wall shade in the area C to D when A to B is as would be expected

Thanks for your help, Mike...You did your best...I understand. Thank you for trying...'appreciate it very much..

Izzie,

I don't use PCS, so I don't understand the details of your screen shot. However, it seems to me that the "working spaces" are the color spaces being used while you are editing the image and the "color management policies" are the color spaces that are saved to the image file. So, in your configuration, I suspect that the color space that was in the file prior to opening it in PCS is being embedded in it when you save your edits regardless of the color space that is being used while you make the edits. It would be a good idea for you or someone to confirm or correct my thinking about that.

Thank you for your explanation, Dave...pure white can be so hurting to the eyes especially as I am downstairs in my laptop here with the reflection of the bright sunlight on the concreted street hitting my eyes. So I apologized to Grahame for jumping in too quick on that because I saw his edit and it matches exactly what I saw in that hospital wall...I may have forgotten to note something in the lighting too...on the lower right side I am not sure because there is another computer there BUT it is facing me, not the wall so I thought it does not matter really...

As to the colour space, Mike tried to help ... but I can be a little bit too strong in my statement because I don't understand how that can happen...

Thank you for your extra help...I do appreciate it very much.

I am really no expert on colour spaces, but from what little I do know ...

If you are processing RAW shots from the camera, the colour space it has set is largely irrelevant - it mainly affects the in-camera jpgs.

If you were using Nikon software to process images (you are not), Nikon's RAW converter might well recognise the camera setting and apply it to any TIF or jpg produced from the RAW image.

However, (as far as I know) Adobe, in LR and/or ACR in PS CS6 will not. I believe they will apply another setting that I believe may be specific to the LR/ACR and different from what's in PS CS6 (particularly with respect to image exporting from CS6) - but now I am mainly guessing.

So this may help explain what's happening in regard to colour spaces (even if I am partially mistaken).


The difference in the shade of the wall at the places identified by Graham's A, B, C vs D is perplexing - I'm sure I have noticed something similar (ages ago) in one of my own shots, it made my head hurt, so I am in denial - it never happened
It begs the question: what do you mean 'the camera never lies'?

Cheers, Dave

Thank you for detailing the problem, Ted...there must be a reason somewhere out there but I can say, I am happy with Grahame's edit...'appreciate your help...really do, very much.

I agree...with you. I tried to change to Monitor Screen but I guess that is only for monitor screen. Not that I am wanting to do a print of this image, but it will help to change it back to default before I forget later on when it causes a problem in my printing something or whatever...

Thank you for your extra help, Bruce. I really do appreciate it very much...

Hi Izzie,

No need to apologise as the only one that knows exactly what colour the walls were is you and an end result would be as you personally want to adjust the image.

The discussion I have raised that Mike, Dave and Ted have commented on is the anomaly of the change in shade/brightness of that wall area just above and below the lower loop of that tube. Not what colour it possibly should be.

I almost get the impression it's got a big soap bubble in the loop but I do have a vivid imagination

But looking more closely I also see some anomalies on the plastic tube edge and the vertical chrome stand in the area that raises the question have you undertaken any work in that area using 'selections' ?

Image forensics experts could have some fun with this one

Isabel, of course his doctors now much better than us but Bill's memory might have weaken because of the anaesthesia and he will most probably get it back soon. I know some old people who get very nervous after some operations and it took them some time to recover from the situation, but they made it in the end :-)

I'm suprised to hear about the breast cancer in men too

I understand Binnur...I don't like hospitals either that is why I keep healthy...hate doctors, hate taking pills and I don't like needles poked at me...one day I might need them but not yet...

Sorry to have been missing, I hope Bill is recovering well & the hospital has recovered from someone visiting them with so much life!
Well done you, I would surely enjoy having you drop by my department!
Lovely fun images too.

[IzzieK]

No other pp there...as soon as I loaded the NEF, it went straight to Camera Raw and then I went to the Lens Correction to enable the Lens Profile Corrections. I did not touch any sliders there, also enabled the Remove Chromatic Aberrations. Did not touch any sliders there either...now that I have thought of it, could it be my enabling the Lens Profile Corrections thing? Do you ever touch/enable those buttons?

Other than those two buttons, I did not correct anything at all, I just loaded them straight in the Photoshop Window because I was trying to illustrate the RGB Highlight Channels and I thought by touching any other basic sliders will ruin that idea of showing how it really looked like SOOC.

Thanks for the extra help...'appreciate it very much..

That must be it! The anaesthesia!!! That's it!!!...the anaeisthologist said he will be a little bit disoriented somewhat and forgetting quickly what I just said moments ago...I am scared to let him drive down the road now that you reminded me of this...I will make excuses to drive with him until he recovers. He is physically OK though and sleeping a lot more during the day, complaining of the heat of course and of so many things other than pain...Thank you for the reminder...

Unfortunately as women, we are more sympathetic to women so we only read about breast cancer in women I think... nor really in men...like as if only women has breasts. For a while there I always suspected that Bill is so caring that he must have been a woman in his previous life...now nearly having breast cancer (the lump was benign anyway...) confirmed that...

Thanks for the reminder, Binnur. Really truly, truly, appreciate that very much...

[IzzieK]

Yes...he's doing fine apart from the forgetful thingie...and boy! don't wish for someone like me dropping by your department -- you will regret it. I love children very much, they will also be laughing their heads off with my antics...

(No, actually, I am very quiet in person...you wouldn't believe what mischiefs I'd like to do that goes through my mind...it is those what ifs can be Dangerous!!!)

Thanks for passing by and commenting and for wishing for something you shouldn't wish for...I appreciate it very much.

A man who was very helpful to me in my career had a benign cancer tumor removed from his breast.

I guess lack of information on men's breast cancer is not much publicized just as much as men being raped...same statistics but it happened...Thanks Mike...Bill's lump was also benign, thank goodness...
