Reducing Filesize for the Web / Albums etc.

I've moved away from my old habit (when first using digital cameras) of fitting 10,000 images on a 16 mb card. OK, that is a bit of an exageration In those days, I never printed anything, so it was never a problem.

Now I do tend to print more, so usually use best quality jpeg for most stuff, and the images are around 1.2 - 1.5mb. I know how to re-size, but even when using 72dpi, and 900 - 1000 pixels for this site, I sometimes cannot get down to the 200kb file size. Sadly, I have to admit to e-mailing myself (told you it was sad) the images from the smallest size I could get using software, so that they were downsized further by Outlook express before they were within the limit.

I'm sure that there must be a way, can someone enlighten me please? I have been reluctant to go down further than 72dpi, but is this the key?

Now a plea to the Crew. I seem to have accidentally over-written the shot of Manhatten I put into the 'landscape' assignment. Is there any chance that you could e-mail a copy to me for my records?

Re: Reducing Filesize for the Web / Albums etc.

You probably want to adjust the JPG compression
100 = low compression
0 = high compression.

I find @ 1:1 I don't tend to notice compression artifacts much over 65 - 70

So by adjusting the compression (format settings usually) you can have a large (resolution) image in a small file size

Thanks for that. I've got a feeling that I did try this, although when I was getting towards pulling my hair out, I can't actually remember. I'll have to have a play around when I get a mo.

Hi Graham, as far as I know we only keep images sized for the gallery but I might be wrong. I'll nudge one of the crew. You can always right click on the image in the gallery and "Save Image As...!

Re: Reducing Filesize for the Web / Albums etc.

Hi Graham

I am not sure what exactly you are asking for in the second part of your post...but if it as Stepheno has said then he is correct, the gallery automatically deletes files that are 'oversize' once they have been used to create files within the limits, so if you uploaded a larger file with more detail and wanted a copy of that then I am affaid that it is not retained at all. The best you can get is the current full size image located at http://www.pixalo.com/gallery/data/551/Manhatten.jpg and the best way to get a copy of that is open it and then 'right click>save as'

If I have missunderstood your request please try to clarify and if we can help we certainly will

Re: Reducing Filesize for the Web / Albums etc.

Steve & Crew - sorry, I was being economical with my posts. The second part is not actually directly related to my resizing question. I just stuck it on the end because it sprang into my mind.

I have accidentally overwritten the file I used to submit the landscape 'Manhatten' in the last assignment with an earlier version. I noticed that the picture in the landscape fortnightly assignment gallery still exists, so I wondered if a copy of it could be e-mailed back to me for my records. I'm not intending to print it, so it does not matter that itis a small file.

I'll start my 100 lines now.

Ahh I am with you now...but my answer still applies, the best you can do is view the full size version of the file and then right click on it and save the file. Hopefully that will help.

As to your initial question I usually use the photoshop save for web fuction which allow me to alter the file size (in kb) to keep it under the limits I need to. Usually I will reducd the file to the dimentions I need in PS, apply any sharpening and then go file >save for web then in the pop up box adjust the slider to get a good balance of detail vs file size. As OrangePeel has said you will be suprised how small you can get the files sizes without losing details.

HTH

Re: Reducing Filesize for the Web / Albums etc.

Thanks for that, Steve. I guess that PSP X will have a similar facility. If not I still have PE2 which may do it. I got brassed off with PE2 due to printing profiles. I could never get it to print anywhere near what was on the screen, but have not had any problems with lesser programs or PSP X. All using the same profiles. I used to edit in PE2 and use Adobe Photo Album to print to get decent results.

My hand aches from doing my lines. Signing off now until tomorrow.
