I have a question about selections in PP.
Why when I make a path for example and make a selection from it every time the selection is 1 pixel wider then the path. I'm used to it with Photoshop and it's very precise even you use the lasso tool and paths. But here I can't understand the logic in that 1 pixel more. Every time I make a selection I have to reduce the size of the selection with 1 pixel and that is very uncomfortable.
what the resolution is on the screen in Pixels mode? Where Corel finds the value of resolution?

I have thousands of images. First: will corel 12 sort images by pixel dimensions? or is there a program somewhere that will? Second: can I then take the smaller images and bulk resample them to 500 pixels on the longest side?

View 3 Replies View RelatedI'm using a Canon 40D, Photoshop 6 and a Mac Mini running OSX 10.8.4.
I'm loading a RAW image from my Camera into Photoshop in 16 bit mode. As I understand it, my Canon 40D has a 12-bit A/D and RAW images have a 12 bit depth out of the camera. Loading them in 8-bit depth would lose some dynamic range/resolution, so I choose to load them in 16 bit mode.
Once the RAW image is in Photoshop in 16 bits, I scroll over parts of the image with the color picker to see the pixel values. This is where I lose understanding of what's going on. The color picker shows pure white values as 32768 and pure black values as zero. Apparently Photoshop (or Camera Raw) is shifting the 12-bit camera data up to fill the top 16 bits in Photoshop. But this is not entirely true! If it truly shifted all 12 camera bits into the 12 MSBs of the 16 bit Photoshop value, wouldn't the max white value be 65535?? If the 12 bits were shifted into the 15th bit, wouldn't the max value be 32767?? Where does 32768 come from? Also, what is Photoshop putting into the LSBs after it does the shifting?
I'm trying to do some averaging of lots of low light exposures using Linear Dodge in 16 bit mode. If photoshop indeed shifts the 12-bit camera values to the MSB of the 16 bit word, I'll eventually run into clipping when I sum my images. I'd have to go to 32-bit mode and that really slows down my system, almost to the point of uselessness.
What's going on in 16-bit mode?
It blows my mind that somthing this simple isnt all that simple. I used the eyedropper tool to slect a color from another photo, then used the brush while fully magnified to change the color of each pixel.
It was coming out a weird greyish color, and I noticed that if I clicked more than once, it got darker, but so did the pixels directly around the one i was editing. So, i copied both pictures, loaded them into paint, and went to town.
It worked, but then when i copied it back into photoshop, it had a black background (there was no background in the original pictures) around the sprite I was editing. I tried to use the magic wand tool to get rid of it, but it took parts of the sprite with it, so...
Is there any way that I can edit the color of a single pixel (or hell, even a group of pixels if they share the same exact color would be nice...preferred, even) accurately? If not, what program could I use that would keep the transparent background?
i want to change the color of a bitmap that i hav in the cdr 11.
1st i draw a circle, then fill any color. then i turn that circle to bitmap by click the option "Covert to Bitmap" as RGB with 300dpi. Then i select that image, then i go to " Bitmap - Creative - Scatter". Now the image is show with edges scattered. After all these ladder i want to change the color of that image by right click on mouse from the color palatte. someone says, go back and change the color and do all these ladder. Its very difficult. i had seen this thing when i went to a printing firm near by.
My CMYK palette is the same hue as my RGB palette right now. I guess you know the difference. RGB looks bright and high in contrast like the ones used in Microsoft word. And the cmyk is, not the bright... Anyway, so the problem is...its the same color on my monitor. Its looks all RGB. On my other PC-2, its the other way around. My RGB palette looks like CMYK. Its not much of a problem with my PC-2 because i rarely use it for photo editing. Its just use for our cutting machine, the other one, my PC-1..
What's going on because it where i do most of my designs. And the color is a major factor there because most of our clients usually send their design to email and they have specific color. So, im having trouble doing designs. Is there a problem with my monitor? I tried editing my files on PC-2 but if i transfer it to PC-1 the color is different again... I cant get the exact (almost) color i want. The adobe gamma isn't do much either nor the monitor adjustment. Do i need to get a professional calibrator for all my PCs or are there downloadable calibrator on the internet? I was about to try the one about CorelDraw 12 Color Management guide but im still not sure about it. I have to read the infos first.
Here's from my PC-1. To the left is the CMYK and on the right is the RGB
Now here is from my PC-2. Left is CMYK and right is RGB.
When viewed from my PC-2..this one looks all CMYK (and dull)
Ideal color settings for exporting .jpg and .eps files for CMYK printing? The default X6 settings result in rather washed out looking exports (both on the screen and on the prints). Black looks very dark grey etc.
Never had this issue with X3 but I understand that X6 uses a totally different color engine so I figure I just need to know the correct settings.
Something strange happened today when I was working on a cdr project. I think I have by mistake somehow managed to completely delete the original rgb palette, copied the cmyk palette and saved it as "rgb" palette. As a result if I try to change the color palette, the rgb and the cmyk options are exactly the same palettes.
This happened whilst I was working on a cdr drawing. Somehow I managed to press a wrong key combination whilst trying to save (probably CTRL-something and then CTRL-S immediately after) and noticed that the colors on my drawing changed. I tried to undo, but nothing happened.
After some checking I realized that the original rgb color palette has been replaced with a copy of cmyk. If I now try to switch color palettes, the cmyk and the rgb are exactly the same palettes regardless of which cdr project I open (new or saved).
This is how I tried to fix the issue:
I tried F8 during startup - no change
I tried with the repair option of the installation cd - no change
I tried a removal and a new installation of the Suite - no change.
Could be worth a try: Maybe someone could send me a copy of their rgbstd.cpl-file so that I could replace mine in the C:Program Files (x86)CorelCorelDRAW Graphics Suite X4LanguagesENProgramsData
How to restore the rgb color palette to it's original status as I work mainly with drawings displayed on the net, not on printed materials and I'm getting desperate as I have a deadline tomorrow.
I have lost the CMYK and RGB color pallets on Corel, we have tried re-installing, but still nothing!
We need these color palletes for printing purposes.
I always use CMYK in my designs and the Pantone color codes for their logo design. I have never had to convert them before and have searched forums and boards with no luck in finding an easy way to do this.

I posted the comments below the link because color management off always pops up in the conversation as it turns to non-postscript devices so I wanted to circumvent the side bar conversation.

First let's get this straight, I've written it and said it about a thousand times, you cannot turn off color management.
When you select simulate color management off in the default application color management dialog, CorelDRAW simply utilizes a different set of color management settings. The rules of color management never change! The application requires guidelines on color and still must have rules that govern conversions, PERIOD.
These rules are not different, only the engines, rendering intents and profiles change. These setting in X5 and X6 can be, in some cases adjusted to simulate previous setting in versions prior to X5 that were labeled color management off, but this label in older versions (X4 and older) were deceptive in their nature, color management was never turned off, just set to a specific configuration.
Simulate color management off (in X5/X6) uses wide gamut cmyk simulation as the CMYK profile, it disengages the color engines (setting CorelDRAW to another internally controlled process) and sets the interface to RGB. It does not turn color management off.
These settings have many uses for industries such as laser engraving and screen printing separations and I support their continued use. Do not confuse this and use these settings for professional output using press work, ink jets or digital printers.
I need to know if i can make a file into a process color like cmyk for plates. How would i do that

In the Info panel, the eyedropper tool displays percentages for every type of color information (K, CMYK), while the "8-bit" field remains blank.

View 6 Replies View RelatedI have recently stumbled upon a problem I cannot correct. I am using Corel 11 and although I have the default CMYK palette selected, all the colors ( for CorelDraw and PhotoPaint) are in 255 percentages as opposed to the 100% CMYK model. I must have inadverdently selected this color mode but cannot figure out how to revert back to the 100% model. This makes it impossible to determine the exact color you want based on CMYK percentages. I know this is a RGB model but all colors are displayed in CMYK ex. C- 233 M- 122 Y- 114 K- 155.
