Question about Canon Cameras

2 Answers

Very poor definition on unsharpened converted raw files to tif format,on my Canon 1DS MKII through Image browser.A number of tests have been carried out under controlled conditions.Both location and studio at an ISO of 100,using a tripod and various Canon L series optics.The results when looking at 100% magnification are poor in both manual and auto focus modes,as indeed are the images when printed out at A3.All the files have been shot without any post sharpening this has been set at zero on the camera body.Please advise Many thanks Mike.

    I should have pointed out the original raw files where shot with the camera body parameters set at zero sharpness.

    I have since carried out sharpening on the tif files at 100% through adobe USM at several settings since, which I consider still to be basically poor when viewed on screen and outputed at super A3 they are as follows:

    1.85% - Radius 1 - Threshold 4

    2.120% - Radius 1 -Threshold 1 & 2

    3.200% - Radius 1 - Threshold 1 & 2

    4.300% - Radius 0.3 Threshold 0

    I have utilised raw files many times on several Canon body's over the years (D30 - D60 - D10 - D5) al of which have not seen such poor definition prior to USM sharpening or indeed afterwards.

    Thank you for all your help and infomation which I have taken on board,I am sure your suggestions would improve the final result.I still feel their are additional problems within the camera body itself.I am converting the raw files to tifs in the same manner I have done in the past on far inferior Canon body's and I have not experienced such disappointing results before,the files are basically unsharp even when taken through USM at 100% at various settings.

    Thank you for your help,I will try going down this route and if it's not successful I will return the body to Canon. Many thanks Mike

    TIFF (*.TIF, *.TIFF)
    TIFF is the industry standard image fileformat. In many ways, a basic TIFF isjust a big array of pixels stored in alarge file. It doesn’t contain much of the sophisticated information used in Photoshop (especially Layers). TIFFs do contain color space information which is important for color management. TIFFs are a very safe way to save your image files since the image is saved in a loss-less state i.e., there’s no data conversion caused by image file compression.
    Use TIFFs any time a file is used outside of Photoshop
    . TIFFs support both 8 bits and 16 bits per channelimages.Adobe has added a new wrinkle to TIFF, saving layers. As faras I know, this extended version of TIFF is only supported byAdobe. I recommend saving any TIFFs without layers.One TIFF option allows compression of TIFF files. Use thisoption rather than image compression for TIFFs to ensuremaximum compatibility with other programs and systems.The other TIFF options aren’t very important and should beleft unchanged.

    for raw files

    Many digital cameras can also save their images as RAW files. These areunprocessed digital camera images. Photoshop can process them to a higher-quality image than JPEG files. One of the biggest advantages of RAW files isthey have more that 8 bits per channel of information and can, therefore, beedited more than JPEG files. Every camera manufacturer has its own proprietaryRAW file format, the term RAW refers to a category of file formats. Itencompasses a wide range of formats include NEF (Nikon RAW), CRW (Canon),as well as many other formats. Adobe Photoshop CS2 supports most RAW fileformats.

We have a Canon EOS 500D. After using it for 18 months we suddenly have a Raw notice and cannot print photos. We dont know where this has come from or to get rid of it. Advise please.

Sounds to me as if someone has set the image "Quality" to RAW files which are more for a professional or advanced amateur use. Page 70 of your owners manual will show you how to set this "Quality" to jpg. I'm going to include a screen shot of this page because it has diagrams and instructions far better then what I can explain just in type.

Also the RAW files you have must me downloaded to your computer, opened in your image software program and converted to jpg file format before you can print, e-mail or any other "normal" thing people do with jpg format.

RAW is just that the actual raw file of the image captured where as the jpg file format is the compressed version with corrections already made in camera. RAW files need correction in post processing.

I suspect you are using the Rebel's direct printing feature which can not process RAW file format, I don't think you want to print RAW as there has been not corrections.

I know this will help.

Here is the diagrams.

Importing Images

The CR2 suffix means that the picture was taken in the RAW file format, a proprietary format. This requires that the images be processed by a software conversion to be 'readable' by the computer. The EOS Utility software that came with the camera will work, as well as a number of third-party software packages. GOOGLE "raw file conversion Canon digital rebel" to see the options.

The other option is to take your photos in JPEG format (not RAW). Your computer can 'read' any JPEG format image.

According to the manual, you cannot change the file type, as it only can save images in JPEG or RAW format.

You can, however save the images in RAW format, and convert them with the supplied software.

Please refer to page 80 of the user guide.

If you don't have the manual, you can download / view it here:

*ist RAW converter problem

Ignoring the JPEG artifacts, which isn't about the extra grain in both the TIFF and JPEG images produced by the convertor, is it possible that different sharpness settings were used for the output images that for the on screen review? High values of sharpening without using an appropriate noise threshold value will have the effect of increasing noise/grain.
