    Hi Guys.:wink:
    I have been with Canon Digital since the days of the S40. and now on my 4th. I have just bought the Eos 400D :heart: and find it to be a delight to use. (NOTE: If you can afford to. buy it as body only and get a better lens. The kit lens (EFS 18 -55 3.5 - 5.6 II) is a fine little starter. But if you want better you need to upgrade). I would reccomend it to any one ..... BUT.... The whole point of going up the megga pixel and well known brand trail, is to get SHARP DEFINITION.... and frankly I am not getting any better than with my G5 which was only 5 Mp.
    I can pop them through Photoshop (It takes a L O N G W H I L E to put 1000 images through Photoshop). and sharpen them up. But to get the full definition it requires 200% unsharp mask. Have you ever seen an image processed with 200% unsharp Mask.... Not pretty. any way why should I spend £500 on a camera which takes soft images....?
    Does any one know how I can get sharp images from the camera? or from a quick fix out of the camera? or is it just My specific camera ? does any one have one which takes razor sharp pics ? etc etc.....


    Many thanks.....:wink:

    I'd agree with bitteraspects about the problem being the lens and not the camera. You said yourself it's a fine starter lens but better to go for a higher quality lens.

    That said, i bought a Canon Digital Rebel a few years back with the kit lens (18-55mm non USM) and got some fine shots with it. I now have a 5D with top quality L glass and sometimes get soft shots so it's not necessarily your equipment.
    check the following-
    • DOF is too shallow and your subject is not plane of focus
    • camera shake can be reduced by using a tripod or decreasing shutter speed
    • try using the flash since it will "freeze" shots better than those with no flash
    • increase your ISO to decrease your shutter speed.
    • borrow a lens to compare images with your lens.
    • try your lens on another camera to compare your camera

    There are so many variables that you could check before assuming it's your camera so check them out and see if things improve

    I have no knowledge at all about the camera and lens. But I will make a comment about unsharp mask and mega pixels. Photoshop doesn't sharpen soft images, it just increases contrast at the edges. If the subject is out of focus or at the corner of the frame where the lens doesn't do too well or has motion blur or is soft for any other reason, Photoshop can't fix it. It can only "mask" it. The image has to be made right in the first place.

    The only time I use unsharp mask is to clean up the image after I resize it. The resizing process can soften things a little and unsharp mask can fix its own issues because the sharpness is already inherent in the image. I generally use between 20% and 30%. It doesn't take much.

    More megapixels will provide more image resolution but not more sharpness. Sharpness is still controlled by focus, depth of field, camera stability and all the other basics of making good images. More pixels will simply provide more out-of-sharp things for photoshop to worry about.

    Let me suggest a little test. If you have a tripod use it for the test. If you don't, then find something stable in which you can cradle the camera to keep it from moving during an exposure. Find a high contrast, brigtly lit subject and focus manually and carefully. Then put that image into photoshop and see if it is sharp. If it is not, then the equipment is probably faulty. If it is, you will have improved your technique and will have learned more about what your camera needs to shoot sharp images.

    I shot this image a few days ago. This is the type of image I'm talking about. It is only a 72ppi JPEG (very low resolution) but it is sharp with no help from Photoshop. See if you can make an image like this with your camera.

    Many thanks for the run down though. It is nice to know that other people would use the same checks so I might not have missed out much.

    Really like the image. at this size mine appear fine. It is only as you home in on them at pixel size that the softness really come through.
    I normally use photoshop at up to 60% depending on the size of the file (bigger files will allow you to use more U/M. although only like you after processing. the remark about the 200% plus was an illustraition to suggest that all is not well. It does pull out the detail at that amount but as you can imagine it is not worth looking at. again (And to every one.) Many thanks for your help and suggestions. I really appreciate it. As no-one has come up with anything that Ive not tried I can at least pat myself on the back for having tried most if not all of the most obvious things. I had though that there may be "in camera" processing involved which I had not found, But if so I still can't find it. A friend with a 5D and a1DMkII gets sharp images out of the camera and to be honest I really don't see why I shouldn't as well. Thanks again

    To post images...you have to use a remote host (Photobucket is a good one)...or if you subscribe to this site, you can upload directly.

    If you try to find fault...you will find it with any image...irregardless of the camera or format.

    I've found that just about all digital images need sharpening of some sort. Digi-cams sharpen the images in-camera (which is why people often think that digi-cams produce sharper images)...and you can set your DSLR to do the same with Jpegs. If you shoot RAW, that shaperning is not applied to the image unless you do it during RAW conversion or later in Photoshop.

    Now THAT sounds interesting.. Not least because it means that I am not necessarily at fault. AND it's not expensive ! ! !
    Many thanks again,

    Thought that I'd try to upload a couple of the images. May be able to see what I mean. worth a try anyway.

    To be honest I rather think the softness suits this one. Although it is not what I was trying to achieve at the time, and would prefer the option of introducing it in a print if I wanted it.
