digital camera download file quality

  dugit 14:08 24 Aug 2004

I have just bought my first digital camera a canon ixus 430 and after downloading files which are jpg (I have Adobe Photoshop Elements)should I then save the jpg files as psd format as I understand that everytime you save a jpg file its quality is reduced?
Also the few pictures I have downloaded so far all appear to be better on screen if Adobe unsharp is applied would the same be seen on actual prints?

Like you, I save as psd. Everytime you make an alteration to a jpeg and then save, it will attempt to further compress as you state.

I find screen images usually improve with a little sharpening. It probably depends on the degree of manipulation already applied within the particular camera.

Printed images likewise benefit from sharpening in my case, but I think you will have to experiment with prints, as what you see on the screen can differ markedly from how a print turns out, regarding brightness, contrast and colour saturation.

Better to keep original jpg intake, just simply copy picture files from digi camrea to computer and then you can do anything you want with other copies.

If you have Irfanview (and it's well worth it) open one of your Canon's picture files.

Then click on the small i within a red circle at the top of the Irfanview panel. You will bring up details of your file including its resolution, original file size (TIFF?), its .jpeg size, date pic taken etc,

The EXIF info button will bring up the make and model of camera, exposure details, whether flash was used etc.

The main reason for saving images in the PSD format is that it preserves any individual layers you may have created. This allows you to work on the image, using each individual layer, over a period of time. For non layered images you can save your images in TIFF format which will allow you to work on the image and save it without any loss of quality from that point on.
