Problems to open CR2 files in CS2

I have CS2 and have always been able to open the RAW files produced by my OlympusC5050. I now have a Canon S95 and photoshop does not open the CR2 files it produces. After some research, I downloaded a DNG Converter and used this. However, the results are far from good, resulting a very grainy image.

Hi Jane,

Your put questions on why the Canon S95 is noisier than the Olympus C5050.   There seems to be several factors:

First of all, there are more pixels on the sensor of the S95, so each pixel is a little smaller, and one stray electron of the noise is a percentage more high maximum value of pixels each additional electron noise will appear a bit more highlight; However, in my view, there are the most important differences between your shots of Olympus green-water and your blue Cannon shots - water:

Because the eye is more sensitive to green, photo sensors are designed to have twice as much green as red or blue pixels, so your green shots will have much more detailed that mask the noise.  In addition, when you balance of a blue more often turned to one that has more red, there is very little red at first, so no noise in the Red is magnified by several times and even with the blue, although that perhaps not quite as well.

If you have a blue shot or a green shot with two cameras, so it would be easier to say what proportion of the increase in noise is due to the color of the light and how is something else.

Anyway, I test to see if the format Conversion DNG using ACR 2.4 compatibility had nothing to do with whatever it is, and it doesn't seem to change what the image looks like, so it's not a factor.

The main problem is that you're using CS2 and ACR 3.x which has the original Adobe raw conversion algorithm (and the worst), now known as process Version 2003.  Two Version of process have been since then: process Version 2010 increased the resolution of the raw conversions so that changing how work in general sharpness and noise reduction and process Version 2012 has added a new way to tone (Lighten/Darken/contrast/etc) images is easier to use once you get used to it.

To illustrate the difference, here's one-by-side, which shows that the way CS2 does things left and the latest way 7/8 ACR or LR 4/5 path on the right, where you will see a more coarse texture and more noise by using the way of CS2 and a finer texture and less noise using the latest methods - click on the embedded image to see larger :

In my opinion, the noise in the image on the left is too, and noise in the right image is deleted too, but I wanted to show how the values of 50% each slide.

What about your computer and the version of LR.  Googling the number of brand and model that you gave and find a 2011 used-computer-to-sell listing with the specifications of the system, it seems that your computer is a Core2Duo with a processor clocked at 1.8 GHz and 1 or 2 GB of memory and you said Vista.  The new version of LR you can run on Vista is LR 4.x that might still be available on Amazon (to the United States at least), but you'd have a good snap up a lot more recent computer and LR 4 or 5 LR on it.  As a kind of i5 or i7 quad-core with at least 8 GB of memory.  It would be a few hundred dollars and a little extra if it's a laptop instead of a desktop computer with the same capabilities.  Make sure you get one with a screen of at least 768 size or maybe it's 800 or 900 pixels high, so you can see all the buttons on the bottom.

Even if you think that, if you want to test how your current computer would work with the newest LR will run on it, you can download the LR 4.4.1 update and run in trial mode for 30 days, by how much you had or do you buy or abandon it.  Here's the LR for Windows download links - click on LR 4.4.1 a:

  • Problems to open PDF files after the upgrade of the file server for 2012 R2

    Hello

    This weekend we have improved our main Windows 2003 to 2012 R2 file server.

    Since the upgrade, users (including myself) cannot open a PDF of the file server.  If I double click on a PDF file, it opens as usual, but if I double click a different PDF, the acrobat reader flashes (in the Task Manager I can see another instance AcroRd32.exe starts and stops) but the second document does not open.

    If I close the first document and then try and open the other, and then it opens without any problem.

    This only affected the opening of files on the new file server, opening several files on a local disk is very good.

    If I disable 'enable protected mode at startup' then I can open several documents of the file server.  I would prefer not to have to do.

    Users are using Acrobat Reader 11.0.10 on 64-bit Windows 7 and Windows 2008 R2 Remote Desktop.

    Does anyone have any ideas, it may be the cause?  And does anyone have one solution other than to disable the protected mode?

    Thank you

    Joe

  • Cannot open .cr2 files in Bridge CS4 v.3

    Past review for hours; can not find the correct answer...

    I just bought a Canon 60 d, where .cr2 raw files. They open in Bridge, which has already opened my Canon 10 D raw files .crw. What should I do to make the .cr2 files?

    I prefer not to install Digital Photo Professional 3.10 Cannon (supplied with the camera) if I can find a solution/upgrade within Bridge/EP.

    Details:

    MacBook OS X 10.5.8

    Bridge CS4, completely updated to v. 3 with Camera Raw 5.7 v. (which are the latest available updates, I think, just updated today).

    Photoshop Elements 8

    Thanks in advance.

    Your CR2 files the 60 d are not supported for your version of ACR.

    Each provider uses different kind of Raw and sadly enough they also use another type of crude oil for every new camera produces. Adobe offers a free upgrade for the cameras, about 3 or 4 times a year. In the past, that they could not get new types of Raw earlier while consumers so often that meant you had to wait a long time before the ability to ACR was there. Today, they have a better relationship and often get pre model of production for the updates are already there when new cameras are entering the market.

    However being a commercial company, they don't offer upgrades for others then the latest versions of Photoshop and ACR. Currently, CS6 and CC are both get updates but the previous version don't are not updated any longer.

    Here is a list of the supported devices and the necessary minimum ACR versions for cameras:

    Another option is available, and it is the free Adobe DNG converter. The latest version is here:

    http://www.Adobe.com/support/downloads/detail.jsp?ftpID=5596

    Or if the link does not do a search on Adobe.com. After the files have been converted to DNG, you will be able to use them in your version of ACR.

  • Problem with opening the files after the installation of creative cloud

    I am under creative cloud in Windows 7. Since the installation of CC when I double-click on a file icon the program opens but the file is not. I can only open the file on the file menu in the program. Very inconvenient. In addition, Acrobat now displays the error message randomly, "Acrobat failed to connect to a DDE server. Does anyone have a solution to these problems? Please notify.

    Hi Rhaydn,

    Test to see if you get the same behavior in a new user account with administrative rights. What types of files and programs were a double click when the application open but not the document? For the question of Acrobat, I found this thread

  • Problems with opening the file with while loop

    Hello everyone,

    It is probably a quick question, but I know how to open data files in Labview. The attached code works if you enter a file from the folder on the front panel button. However, if the path is empty and you press the run (arrow) button, a dialog box appears and asks you the file.

    I select the file, but the dialog box keeps coming back. I think it has something to do with my while loop. Can someone tell me where I'm wrong?

    Thank you!

  • I can not open JPEG files. When I try to make my computer goes to the word and gives me strings of unreadable code. How can I correct the problem and open JPEG files?

    Cannot open JPEG files. Computer to the word when attempted and gives the unreadable code strings. Corrective action?

    The file association seems to be incorrect.  To rememdy this...

    Right-click on any jpeg and select 'Open with' in the menu.

    From there, you should have several options, select Windows Picture Veiwer or anything that makes sense on your pc.

    If it opens correctly, close it, and then right-click again.

    Rather than choose the same program, at the bottom you should see "Choose program" click on it and select the application that worked, then check the box that says "always use the program selected to reopen this file type."

    OK out of there and you should be good to go.

  • Problem in opening a file specific exe on Windows 7

    I recently bought a new computer with Windows 7 Home Premium to replace my old computer with Windows XP. I have a specific program that I have used for more than ten years for web design. Bought legally online. Unfortunately, society is no longer exist, and the possibility of obtaining a replacement download does not exist, other than the natures offered free copies that are labeled with ads.

    I have the exe file of the program that I placed in the folder of the program since I have no installation disc. I can handle open the program, but it does not past that point - he just continues to run without opening the pages I work on. Thinking it was a Windows 7 compared to Windows XP problem, I downloaded XP using Virtual Box (a whole all except nightmare) and the program worked for all of an hour, but then, too, just kept running and not to open the pages needed.

    I ran analyzes viruses and malware on the computer. It's clean. Microsoft Fixit does nothing to correct the problem. Windows tells me that it is compatible. Place the file in the folder of the program created the problem? Anyone has any suggestions on how to get this program to work? I have to reconnect my old PC to edit my web site?

    EXE files in general can only be transplanted, they must be installed so that all the DLL paths and libraries and the supporting registry are included.  Unfortunately without installing it, Yes, you will probably not be able to use on your new computer.

  • problem to open a file, .tiff due to lack of memory

    Hello

    Someone knows it why Photoshop elements 12 (32-bit) blocking (summary of the message displayed: refusal to open because of lack of memory) a type 272Mo .tiff file?

    Same problem when 3 giga (the maximum allowed) are allocated to the application via its menu preferably General.

    Runs on a HP with Windows 8.1 64 bit, core i5 and 8 gigabytes of memory is 6 giga of free before starting the application Photoshop element.

    Someone a you it a solution?

    Kind regards

    Patrick

    Hello Michel,

    The problem came from the installer that by default installs the 32-bit version and not the 64-bit.

    So I uninstalled Adobe Photoshop elements 12 keeping my settings (choice to make when uninstalling) and I have loader Installer and I opened the downloaded folder and proposed the ad hoc Installer.

    Result, my .tiff file opens without problem in the 64-bit of the software version. I left the default memory allocation value in the sub menu Preference.

    Kind regards

    Patrick.
