RGB values (eyedropper) where ot find in Aperture?

Where can I find the eyedropper tool in Aperture? I want to check if in fact my greys are neutral... Can't seem to find it!

Although Aperture does not have this built in (an
oversight to be sure) there actually is a pretty good
alternative shipped with every Mac.
Actually, it’s useless for the task. It’s NOT providing RGB values of the image data but the color sent to the display. We need RGB values of either the internal HDR color space (that is being represented by the Histogram) and/or (better) whatever output color space you need to export the files. Aperture provides neither which in my mind is very confusing.
While many have said Aperture is lacking due to lack of curves, the lack of an info palette is a far bigger issue.
It would also be lovely if the Histogram would represent the rendered data based on my selection for a color space I’ll encode the data. Adobe Camera RAW provides this (toggle the output color spaces and watch the Histogram update). Not the case in Aperture. So I have no idea, based on the gamut of the scene if I want to encode in ProPhoto RGB or Adobe RGB (1998). If scene gamut fits within Adobe RGB (1998), I'd rather not use ProPhoto RGB. In Aperture, I’m flying blind.

CO-PA: Value fields - where to find? Function Module?

Hi there,
I want to select all the available value fields (VV010, ...) that can be included in tables CE1xxxx and CE2xxxx. Is there any Function module or table where I can get the (value) fields from? I don't want to create static coding that includes the fields that are included in this structures in this moment. My report should be as flexibel as it could be and so I'm looking for a possibility to get the VV-fields in the named tables.
Will thanh you so much
Kind regards
Max

Hi,
There are two tables you may need to refer to.
The table TKEF is the field catalog table and contains all fields and their attributes in the system, from where you can identify the value fields. Table TKEFE lists the fields assigned to the operating concern.
You may also look at the program RKEREOFC to identify a FM or method for your use.
Cheers.

RGB values

I know my iMac has a digital color meter in it (finder, utilities, digitalcolor meter. But its giving me sort of funky readings off my photo's. I'm making a zone system for my camera for a class (ugh awful assignment).
I have Aperture, can I see the RGB values on my photo's with Aperture?
(I have photoshop as an external editor added to my aperture but I don't know how to find that info in Photoshop either)
Help!
Susan

(I have photoshop as an external editor added to my aperture but I don't know how to find that info in Photoshop either)
Kirby's advice should suffice.
FWIW,
I use PS full version (not Elements), so not sure if it is the same, but in PS full version you use 'Window Menu > Info' panel. Using the eyedropper tool gives you access to both RGB and CMYK values at the same time as you drag over image.
Clicking with the eyedropper tool also allows you to set the foreground or background color (whichever is in front in tool panel) to the sampled color.
Good luck with the assignment.

Pixel counts for specific RGB values

Can Photoshop CS4 find pixel counts in an
image for specific RGB values? Where would
you input these RGB values and would you see the pixels highlighted and totaled?

Hi Zeno:
Thank you very much for your response!
Your directions work very well for a single image. I have an entire series of images and was wondering if I could just enter a specific set RGB values some where and see a total pixel count for each one of them.
When I go to foreground color and enter the RGB values there and then set the color range to zero and press OK, I get a Warning: No pixels were selected message.
Any additional advice that you have would be much appreciated.
Thanks, Bretzfrog

How to find the RGB Values of a Color for Hyperion

When customizing your Hyperion forms, we come across situations where we need the exact RGB value of a given color. This article explains a simple technique to find the RGB values using MS Paint and the Calculator applications that come as standard applications with your operating system.
Here are the steps to find the exact RGB value of a given color.
1) View your Hyperion form using IE, scroll down until you see the color you want to find the RGB value and press the "Print Screen" button (in your keyboard).
2) Open MS Paint and click Edit -> Paste or simply Ctrl+V. What you saw in the browser will be copied as a new untitled image.
3) Select the Color Picker tool and click on an area that has the color you want to match.
4) Now go to Edit Colors... option and click on the "Define Custom Colors >>" button. The color you picked will be selected on this palette. At the bottom right hand corner you will see the Red, Green and Blue values you need. Note down the R,G,B values (given in decimal).
5) Now we need to find out the hexa-decimal values that correspond to those decimal values. This is where we use the simple Calculator. Open the Calculator application from Program -> Accessories. Switch to the scientific mode by clicking View ->Scientific.
6) By default it will be in the decimal number mode. Enter the R value (238 in this example) and click on the Hex radio button. The corresponding hexa-decimal value (EE in this case) will be shown in the dial.
The selected color in this case has the same value for R, G and B. (In fact, all shades of gray has the same values for R, G and B.) Therefore, the RGB value of the background color that we need is #eeeeee. Repeat step 6 to find out the hex value for the Green and Blue elements, if they are different.
Tip:
If you find it difficult to pick a color, zoom the image by pressing Ctrl+PageDown or using View -> Zoom -> Custom... option.

These tips are to find the RGB color of HFM default row where row is text and text lines in data columns are also visible to business users as Yellow as an input cell. By applying the same RGB color you can apply the same color to your data cells or rows. This post shows how to identify color from any web view-able object.

New to Kuler- where are the RGB values?

Hi I'm new to Kuler-
When I go to the main web site there are a lot of beautiful
color sets on the first but I see no where, where it says what the
RGB values are.
What am I missing? I didn't find any thignin the help files
either.

you have to sign in, then go to Create - the colors will be
displayed in either rgb, hex or various other ways ~ O_O

How to find RGB values of an image in MIDP 2.0?

I am builiding a midlet in which i m supposed to take an image and than i want to find RGB values of all pixels
.After Finding the RGB values i want to store them in an array,and sort that array to find 5 Most repeated element of that array.Also i wanna construct color from those 5 Values and Display Those Colors.Can Anyone
Guide me Through This?

I have not used Vision much but I would be very surprised if you would be able to do this directly. It should be straight forward to get an average intensity with or without Vision (convert image to 2D matrix and average the values, for instance) -- the difficulty will be correlating the calculated values back to Lumens, etc. This could likely be done but it would probably require you to come up with the calibration curve and would be sensitive to setup changes, dust on the lens, equipment aging, etc. and these things should not be discounted. This is why, particularly if you're in a production environment, you'd probably better off buying a commercial meter and talking to it via a driver than to try to do it yourself -- they've already taken these things into account.
One more thing, in the picture you attached, any luminosity calculations you made would probably be skewed low as the white is saturated (railed) in spots and those under-reported values would affect your average. If you did try to come up with a Lumen calculation, you would probably want to turn your aperature and/or exposure down before creating the calibration curve.

How can I select an area of a picture (larger than one pixel) and find the average RGB values of all the pixels contained inside the area?

I'm analysing the differences between several different images and I would like to select a large area of each (such as with lasso tool) and find the average RGB value of all of the pixels within the selection area made/

With the selection you could do a copy paste and use the histogram of the new layer set the histogram source to selected layer. The eye dropper sample size may also to get the average of a square area around a point.

DigitalColor Meter - RGB Values Don't Match?

I've saved a 16 color palette under 'Colors' in the 'TextEdit' application. Each color has been set by directly typing in the values for R, G and B, for example one of the colors is R=68, G=255, B=153.
If however I open the 'DigitalColor Meter' application, which is set to 'RGB As Actual Value, 8-bit' and move the aperture over the same color in the 'Colors' window the DigitalColor Meter reports the RGB values of that color differently to what was set. For the color mentioned above it reads R=73, G=250, B=151.
Why don't the two match as they should? This happens with any color, but not black, white or a shade of grey.
If I save an image from a website by draging the image to the desktop then open the image and use the DigitalColor Meter to compare the RGB values of any given pixel in the saved image to those of the same image displayed on the webpage then again the RGB values between the two will not quite match, but black, white or a shade of grey will.
If however I save the image to my desktop by using >Apple-shift-4 to grab the image then the RGB values do match.
Can someone explain exactly what's going on? Does it have something to do with perhaps OS X applying gamma correction to the screen so that any image displayed on the screen will have its RGB values slightly altered?
If this is the case why isn't the DigitalColor meter affected or does it read a pixel's RGB values directly from graphics memory instead of screen memory where the gamma correction is being applied, not that I know how a Mac's graphics are organized, but I'm assuming anything to be displayed on the screen first has to be fetched from graphics memory.

Well this is a day of debugging I'd rather have back.
With a form of Rubber ducking my colleague helped me notice that the number of items being displaced was equal to the number of page zero item I added recently.
These items were placed in my menu region, which happens to be region position 7.
I had commented out a section of my page template

but this content was obviously still being generated.
At some point during the page submission, this disturbed what apex was doing - somewhere these 'duplicated' yet commented field definitions were causing apex_application.accept to store the values in locations offset by the four P0 items.
I often look to page zero for potential causes to strange issues - but this one initially beat me.

Hi people,
I'm typing from Brasil, sorry my English.
I have a iMac 21,5" Intel mid 2011 and I need to know if is possible I change the original 500Gb HD for a 512Gb SSD?
I intend to keep the original DVD driver and install the SSD in the same HD place.
If yes, where I find a tutorial about this?
And I will like to know if the 512GB Solid-State Drive Kit for Mac Pro is compatible with iMac.

Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
Instead of HDDFan Control, get the free SSDFan Control

How can I convert (or switch) the RGB percent values from the LR histogram into RGB values which are shown e. g. in PS/CameraRAW?

In LR 5.5 (same in previous versions) the RGB values in the histogram are shown in percent (relativ) values. I prefere to see the absolute values, but I can`t find any way to switch. Maybe this option is intentional disabled, because LR works in 16-Bit mode this would result in values up to 2^16. But as i compared the relativ values from LR with the absolute values from PS i run into a conversion problem. The following example shows the differences:
CameraRAW : RGB, 128,0,0
Lightroom: RGB, 43,8%, 19,0%, 6,2%
CameraRAW: RGB, 0,128,0
Lightroom: RGB, 29,8%, 47,5%, 17,5%
Mainly i have two questions:
1. Is there any possibility to change the percent RGB values in LR to absolut values?
2. How can i convert CameraRAW values to LR values (see above)?

TThe reason that a design decision was made from the beginning of LR to show only the percentage values was that RGB values are dependent on the color space and the LR histogram and numerical readout are derived from the Develop module's display space which is a hybrid color space with ProPhoto RGB primaries and the sRGB TRC. Thus the numerical values in the display would be different from the exported RGB image (in an orthodox space) and it was feared that this would be misleading. When soft proofing was introduced, because it involved converting the display to an orthodox space, it became possible to use the 0-255 scale in that mode.

Error handling for RGB values

Hi
I am having problems doing error handling for RGB values. I have a Java applet with 3 JTextFields whose values are parsed as int variables and stored as ints. If a value is entered that is not a value between 0 and 255 is entered, the appropriate field/s should be set to an empty string.
The problem I am having is that I am using try/catch block to try to parse as an int but then it breaks out of execution completely.
I hope this makes sense and that someone can help.
Thanks!

this is because your code is probably inside one giant try catch block, what you need to do is have small ones in places where you do the parsing.
post code and i can show you how to modify it

PMS RGB Values Different in Illustrator & PhotoShop

Hello, Forum;
I'm stumped here. I'm working on a project that has me going back & forth between PhotoShop & Illustrator, working in PMS color. I've noticed that the RGB values for a given PMS are significantly different between the two environments. For instance, PMS 383C in AI is
R:178
G:187
B:30,
where the same 383C in PS is shown as
R:162
G:173
B:0
Why would that be?
Thanks.

System colors do not give correct RGB values

When using the IMAQ integer to color value function, I get correct RGB values for colors chosen via a color box control - except if the colors are selected from the “system colors”. Is this supposed to happen? The RGB values for the system "White" is: 0, 0, 9.
Attachments:
ScreenShot010.jpg ‏21 KB

That function does look at the most significant byte. Try wiring the system color to a "Split Number" (numerics "Dat manipulation) to split the I32 to two I16 and then again to get four I8s.
You will find that the "other" bytes has a "1".
System colors are special.
