Green in Blurb ICC profile
Book Design and Imaging

… and one more question – how do you adjust landscape pictures? (I mean no sea or desert pictures). :-)

Green in Blurb ICC profile
Book Design and Imaging

Hi Joe, thanks a lot, what a shame. It also explain, why I cant get nice colors of yellow-green lawns and grass.

Does it mean, that all books in Blurb are printed with Blurb ICC (CMYK in fact), whereas in your link it is mentioned, that blurb uses HP Indigo which uses sRBG?

 Thanks 

Richard

Green in Blurb ICC profile
Book Design and Imaging

 Hi, I have serious problem with soft proof of green color. Monitor calibrated. I am not able to adjust this piucture under soft proof ON to be same (or similar, at least) as original sRGB.

Any ideas appreciated.

 Thank you very much

Still confused about Blurb ICC profile
Book Design and Imaging

Some additional information – proof setup with perceptual is slighly richer than relative colorimetric. Any important difference?

Still confused about Blurb ICC profile
Book Design and Imaging

Hello  to all.

 I use Adobe RGB profile and RAW out of camera. Convert into tiff and in Photoshop convert into sRGB ICC. Then I swich on soft proof with Blurb ICC profile.

My question is:

Should I do all contrast, color, masking, etc.  activities with proof ON? Does it mean, I see final result on my monitor (I calibrate my NEC with Spectra View II)?When I finish my adjustment work, my picture is still sRGB saving as jpg with ICC checkbox OFF.

My trouble is:

Now I have lot of rich and deep green colors of lawns, trees, plants in sRGB and viewing in ICC all change into blueish, washed, hazy greens. I can do what I want with curves, light, color balance, but no same result as seen in sRGB.

Hope my English makes sense.

Thank you for assistance.

Another color management question - could not find answer so far anywher...
Book Design and Imaging

Let me ask one more question. It is partly in my first question, but no solving  yet.

 I am confused in sRGB with/without bpc.

I open a picture, convert into  sRGB IEC61966-2.1. Then I do view > proof setup > custom > device to simulate: sRGB IEC61966-2.1 > rendering intend: perceptual > black point compensation: checked. I know, bit silly, but pictures are NOT same!

When I  convert into sRGB IEC61966-2.1with BPC, then  view > proof setup > custom > device to simulate: sRGB IEC61966-2.1 (only) and pictures ARE same.

How it is possible?

Thank you very very much.

Richard

Another color management question - could not find answer so far anywher...
Book Design and Imaging

Thank you very much for you answers and suggestions.

Last night I did some experiements with following results:

I wanted to know if the trouble with wrong color in BookSmart is due to no color management in BookSmart, so I converted picture to the profile of NEC monitor (saved after calibration). Once I saved it with Save options > Color > ICC profile CHECKED, once with UNCHECKED. Those with unchecked (as recommended in Blurb help) filed was correct on my monitor, the other wrong again. To be honest I have no idea whats going on with checked/unchecked filed and what is this good for.

To your suggestions:

- I can  change color profile in Camera Raw (which is part of PS). When I open the picture in PS I control the profile under the picture, where I have sRGB. If I would have different profile from working space, warning table would jump out. But as I open sRGB into sRGB there is no need to convert.

- I could use Nikon software to convert picture from RAW (NEF) to sRGB Tiff and open it in PS, but Nikon software is slow.

- I work only with 16bit pictures.

-  Finally I think that all wrong colors are only question of wide gamut monitor, because in other software with color management system pictures are OK. But wrong and same where no color system is adopted. So I think book will be OK in spite the fact I can see it properly, because information about profile is in pictures, only my monitor is not able to show them properly. Any idea how to change setting of my monitor?

 Thank you very very much, I wanted to give the digital photography up and start with poems. :-)

Another color management question - could not find answer so far anywher...
Book Design and Imaging

I have been spending last two day searching any help for my problem with PS and Blurb color management. Basic problem is that my final and saved image from PS is different in colors from picture importing into BookSmart programme.

My software and setting are as followed:

Monitor: NEC P221W, calibrated with i1 and SpectraView II software, profile saved (lets call it NEC profile)
Windows: Windows 7
Photoshop CS4, working color settings is sRGB (edit > color settings > Custom – sRGB IEC61966-2.1) – correct?

1) shooting with Nikon D90 into RAW (NEF) in sRGB (could change later anyway)
2) Saving pictures into Hard Disk
3) Open RAW into PS CS4 through RAW Edit (or what is it), doing basic settings
4) Open into PS CS4
5) Do all I need to do with my picture
6) view > proof setup > custom > device to simulate: sRGB IEC61966-2.1 > rendering intend: perceptual > black point compensation: checked
7) It seems to me to be a nonsense to proof sRGB in sRGB, but picture differs. ???
8) Smae nonsense, but anyway, edit > convert to profile > destination space RGB: sRGB IEC61966-2.1 > perceptual > black point: checked
9) transfer from 16b to 8 b
10) sharpening
11) save as > jpg > icc profile: unchecked
12) open BookSmart
12) open saved picture and move it into the page
13) picture has more reds, it differs from one just saved in PS, when I set proof in PS into NEC profile, both are same.

I dont know if final book would have sRGB saved from PS or reddish picture seen on LCD monitor. How to set booksmart or my monior to see what I will have.


One picture opened in different software with this results:
PS and Zoner Photo Studio (with color management system) same and OK
Windows explorer view and IrfanView and AcdSee and BookSmart and PS with NEC profile same but NOT CORRECT (more reds)

Please, help.

Thank you very much!
