Thanks for your reply Alan but what I am trying to reduce is scanned slides, (not RAW digital at the moment) I downloaded Fastone but not being very clever I don`t understand how to get just the photos I need into the programme. Can you advise please.

Thanks Alan, I will have a go at that and let you know. As I said I`m a bit thick when it comes to this digital stuff but will have a go.

Thanks Brian but as I just replied to Alan I am trying to downsize scanned slides, not RAW as yet, but I take on board your advice about making the change in camera when I shoot RAW. I have Elements 7 and I understand that you go onto image Resize etc but I don`t know what measurements to use to reduce the file size to 20mb. Hope I have explained myself a bit better. Also see my reply to Alan. Any further help would be appreciated.

I'm not familiar with fastone. However, in Photoshop you go to image>image size>click resample and input the dimensions of one side of the photograph. To get a file that exactly 20mb it will need to be 7.88x9.853 US inches @300 dpi. That will get you a file that is exacly 20.00mb. I haven't worked with Fastone but I suspect the operation will be similar.

The other way to do it, and it is faster, would be to set you cropping tools to the above dimensions and resolutionand then crop each photograph. Along that some line, if you needed a smaller file, just lower the resolution and experimetn til you get ths size you need. Hope it helps.

Is there some magic to 20 mb? Just asking. If you have Photoshop Elements, you can try to calculate the size as Nathan suggested. I see the file size of JPEGs from my camera jump all over the place depending on what is in the picture, even though the dimensions are the same for all photos from the camera.

If you just want a smaller photo file to email, you can save the file (use a different name) with more compression. Here is your photo at quality 11 instead of quality 12 and Photoshop says the file size will be 16.7 mb. Depending on use, you could get down to quality of 8 or 9 without most people noticing. For your own use, however, scan at the maximum resolution you can and save the files at the original size without compression for maximum quality.

Thanks for that info. The reason I mentioned the 20mb is that I am uploading images to another website that I have just set up www.australia.imagesandprints.com and the file size can`t be over 20mb, so I am actually trying to get it probably just below that. A lot of slides I am scanning are larger than 20mb. So Iwill try just dropping the quality as sometimes I have it at 12 and other times at 8 . I didn`t know this had anything to do with the file size. Once again thanks for your input.

Why do you want to upload the scans in full 20-25 megapixel size? Is it for printing, or for demonstration purposes? Frankly, there isn't 25megapixels' worth of image in them, your scanner outresolves the film it seems. Reduce the size 50%, to 12 megapixels, and you will save a bundle of server space and not lose any appreciable detail either.

If it is for on-screen viewing, I'd strongly recommend that you resize them to something a bit more reasonable and sharpen them for the purpose. Personally, I normally use 1024 or maybe 1280 as the longest dimension on photos I upload for viewing; it will fit on most computer screens without any need to resize in the browser.
