    RTBM! - Colour Mode

    Well, playing around with the D80 and comparing shots of the same spot, with the same F stop, shutter and ISO, my manual images looked much more underexposed. I thought, whats going on here? Why are they different?

    After comparing the image exif data, I noticed that the colour mode was different. So I thought (again - head hurts), why dont I "Read The Bloody Manual?"

    Well, im glad I did, as the colour mode I was using was meant for "as is" photos for print. The mode I should be on is IIa (RG which, as the manual says "is adopted to the Adobe RGB color space, which supports a wider gamut of colours than sRGB" and "Prefered choice for photos that will be extensively processed or retouched"

    All these pics ive taken so far I had in the incorrect mode. If you think that it shouldnt make much of a difference, try it out (change your colour mode to IIIa sRG.

    Cheers,

    I've always found the more I read the less I know and the more confused I get.

    Just do it !
    It's not broken. It's "Carbon Neutral".

    Yes and NO,
    Adobe ARB gives the person who is going to do the printing more color options and at the printing stage always there is time to convert the image to sRGB.

    95% or more of the pro photographers (images for magazines, books etc) are using Adobe RGB.

    If you are going to post images on the web then just use sRGB because the colors looks better on the uncalibrated monitor

    Have a look HERE where is more info about it.

    The person who do my printing ask for Adobe RGB and on Tiff format to be able to PP the image for his printer and the paper selected.
    Once I sent an image in sRGB and the color palette was not good enough to print.

    Carlos, the reason why it is recommended that images for the web beconverted to sRGB it is because Firefox and Explorer did not used to read Adobe RGB.
    I believe that now Firefox have an add on to read Adobe color space.
    Other good reason to use sRGB is for those who only take shots in jpg and get the images printed in the mini labs.
    The consistence of the colors in the minilabs are better using sRGB.

    Louie Aguinaldo explained it very simple [ame="http://digitalphotographer.com.ph/forum/showthread.php't=520"]HERE[/ame]
    QUOTE:
    To be able to utilize this color advantage, you would have needed to capture your image using the Adobe RGB color space in your DSLR (if your camera is capable of doing so). Or you can achieve this by shooting RAW and converting to Adobe RGB upon post processing. It will not work if you captured an image in sRGB and then convert to Adobe RGB in photoshop. If the colors were not captured to begin with, converting to Adobe RGB will not create those missing colors.

    Now the question is when do we use Adobe RGB and sRGB?
    The general school of thought is to capture and edit in Adobe RGB, and if necessary, convert to sRGB. Yet, for practical purposes, you might not need to use Adobe RGB in certain situations.

    1. If all your images are just to be shown on the web or to be displayed on the computer, Adobe RGB becomes an extra unecessary step. What you see on the web is limited by monitors. sRGB is a color space based on typical monitors. Thus, if you want colors to be accurately represented, you would need them to be in sRGB. If ever you try to display an Adobe RGB image on the web, you will notice that the colors are very much off.

    2. If you are not overly critical about color and will only be printing with Minilabs, then it might be practical to just work within the sRGB color space. Most minilabs are sRGB by default and cannot handle Adobe RGB images. If you try printing an adobe rgb image you will also end up with colors that are off as they will be interpreted as sRGB images.


    Looks like that an Apple 24"monitor and calibration gear is on the shopping list

    I think ill keep to Adobe RGB on the D80 and PP workflow will mean converting to sRGB prior to uploading to web... when I think will be when saving from RAW to TIFF - unless this is not a good idea.
