Hahnemule, Canson, Redriver, and Moab all have ICC. ICC profiles are binary files, and are opened automatically by Photoshop, the operating system, printer drivers, and similar files. Profiles need to be installed in the correct location on your computer for them to be available to image editing and other applications. These locations are:.

Contents Color basics7 / 10Assigning an ICC profile to an imagePublished on April 15, 2015 / Updated on April 21, 2019'Assigning a profile' is a fundamental concept in color management because it is the beginning of the story of our photos.Since there are more or less large color spaces, ICC profiles for each device, it is now necessary to know how to communicate the right color, the 'same color' as much as possible, from one device to another, taking into account their characteristics or defects. Communication of the 'right color' begins with assigning the right ICC profile to an image. Let's see why and how now.Why is it necessary to assign an ICC profile or color space to an image?Essential! This paragraph is one of the most important paragraphs of this site. A cornerstone!Assigning an ICC profile or color space to an image allows it to display it correctly, quite simply! The RGB values of the file will be 'translated' by the 'good' colors so the good colors L.a.b. Let's look back at the history of an image file since the beginning of its history.All cameras, even smartphones, can't take anything other than a RAW file.

This one is therefore developed internally by a kind of mini-Photoshop in order to provide you with a nice JPEG file. The management of the colors of this photo and therefore the succession of the two fundamental stages of the history of a photo, i.e.

'the assignment of a profile' and then 'the conversion to a color space', is therefore done in a transparent manner for the user and automatically. Without color management no colors, even in a smartphone!My RAW file is therefore a digital negative. On pro or some amateur cameras, you can retrieve this RAW file to develop it yourself in demo software such as. We will see below how it works then.

But let's start with a smartphone or an amateur camera because they directly deliver a Jpeg file without any other possibilities. However, they will necessarily and above all take a photo in RAW format which will be developed internally by the internal mini-Photoshop in order to deliver your image in the form of the famous JPEG file.Assigning an ICC profile or color space to an image allows it to display it correctly, quite simply!So how does it work?In two steps, invariably.

And according to this analogy with the story of a bank note! You find a 100 something bill on the floor. It is a currency unknown to you. So you obviously can't use it in your favorite stores!

How

Two things will therefore have to be done: find out which country it comes from to give it a 'universal' value and then convert it into dollars. This sequence 'give it a value' then 'convert' it is called in color management 'assignment' then 'conversion'.So first of all, we must give it meaning, find its country of origin to give it its universal value.

OK, it's 100 things, so it's completely unusable in the United States! In color management we would call this 'The assignment of a profile'. They must therefore be converted into dollars according to the exchange rate of the day, i.e. According to a universal value - let us assume gold.

In color this standard is called the L.a.b. color space. This is called 'conversion'. The value 100 of the departure ticket is always 100 when it is identified as 100 something. When you give it meaning. In a photo, the assignment of an ICC profile does not change the RGB values of the file. Simply, RGB values are displayed 'correctly' and no longer in a factual reading.

Then we convert it into another currency, for example into dollars and they become 10 dollars - so with the same absolute value - my 100 have become 10. The L.a.b.

colors are identical but the RGB values of the files are modified. 1 - JPEG photo case: assigning the camera's ICC profile to the image directly in the imageThe 'mini-Photoshop' of the camera must read the RGB values contained in the photo and translate them into the 'right color' and therefore into its 'ideal' L.a.b. colors. An RGB signal 255, 0, 0, 0 should be displayed with a red but with which red L.a.b.?

This is done by reading the instructions in his ICC profile.Let's say you took a picture of a perfectly grey wall. Your Jpeg photo should be perfectly grey at this point and therefore your file should have RGB values of style 128, 128, 128. However, your camera has some defects and the RGB values recorded are more like 128, 138, 126.

If you display these last values in Photoshop, you will see a greenish-yellowish grey instead. That's why you're disappointed!

But as the manufacturer of your device knows that it has these defects, it has calibrated it so it has noted its defects in its ICC profile i.e. In a table (a matrix table) where it has noted: I show you a neutral grey 128, 128, 128 and you record 128, 138, 126 in the RAW file so with a dominant ugly color! Thus the table tells him if you find an value RGB 128, 138, 126 you display a color L.a.b. 54, 0, 0 therefore a value RGB 128, 128, 128 and not a strange grey.The RGB value of the file is correct and always 128, 138, 126 BUT the device acts as if it was 128, 128, 128 at the time of its display. Assigning an ICC profile therefore serves only one purpose: to ensure that RGB values are correctly interpreted and therefore displayed without seeking to match RGB values with their 'logical' display.

An RGB value of 128, 138, 126 has no reason to display with a medium neutral grey without an ICC profile. An ICC profile does not transform a file. The RGB values of the RAW file remain the same but are then interpreted correctly. It's just an instruction manual, a post-it attached to the RAW file to tell it how to correctly display/view its RGB values.The RGB value of the file is correct and always 128, 138, 126 BUT the device acts as if it was 128, 128, 128 at the time of its display.

It's just an instruction manual, a post-it attached to the RAW file to tell it how to correctly display/view its RGB values.Then, it will be necessary to match the RGB values of the file and the display of the file. Indeed, the eye sees a beautiful neutral grey but if we place the Photoshop eyedropper tool on this grey, it shows us 128, 138, 126!!!!

It doesn't make sense! This alignment is called conversion and we will see this in detail on the. 2 - Case of a RAW file processed by yourselfAs I explain below on this page and on my pages dedicated to the or,The ICC profile is also assigned automatically when you open your RAW file in the demo software. Opening a Jpeg, Tiff or PSD file,.Opening a 'classic' image file in Jpeg, Tiff, PSD, etc.When you open a Jpeg, Tiff or Psd image without an ICC profile (i. Without color space) in Photoshop (unlike a RAW file as we will see later), this one, if you have chosen to enable color management in this software (see for more information and sample images), warns you and asks you to choose one. This is done either when the image is opened directly or, once the image is opened in Photoshop by the Edit menu / Assign profile.Let's take an example with an image from my old scanner that I open in Photoshop correctly configured on my calibrated screen:So I open this image - an IT 8 test chart - from my scanner (figure.

To understand this, I chose to open it without an ICC profile (figure a below left) - I did not assign the ICC profile of my scanner to the image opening - but as Photoshop necessarily needs to assign an ICC profile to an image to display it, it will force an assignment and in this case it will assign what is called its RGB working space. Here the image opens in Adobe RGB since I had chosen this color space as my RGB working space at the time. The image is displayed with arbitrary default colors, as if it were an Adobe RGB image.

Each pixel contains RGB values that are interpreted in this working space. In the image on the left below, you can see that the grey of the test pattern is reddish.

Indeed, in the Adobe RGB color space, the RGB value 98, 91, 87 are red. For my image to regain its 'true' colors on the display, I must assign it the 'right' profile, his! On the picture below on the right, I have assigned the profile of my scanner to my image and my grays regain all their neutrality!

It's magical. And you will find that the RGB values are always the same. The RGB values of the info palette do not change BUT the displayed colors, the L.a.b. colors change!

Assigning an ICC profile only changes the display of a picture for given RGB values.The image to which the correct ICC profile has been assigned is simply displayed correctly, here on the right!To do this, I used the 'Image/Mode/Assign Profile' menu from Photoshop up to PS CS2 and the Edit Menu/Assign Profile for PS CS3 and later versions'. Taking into account the characteristics (defects) of my scanner when reading its ICC profile, Photoshop now knows that for this device a signal 98, 91, 87 should be displayed with a neutral color, a neutral gray and not a reddish gray. The image has also recovered a normal contrast.
