Thread Title: How to increase size of jpeg images Added by Suman Das on 22/Dec/05 at 11:07:37
I usually take my pictures with a D70 set at JPEG Fine which produces 6MP pictures with a filesize of 3MB each. I need to increase the file size to 18MB for a storybook album. How do I do this? Please can you help. Thank you. Suman

Suman, when you open these in an editing program you should have a file size of about 18mb. I say should, meaning it might be useful to open one and let us know for sure.
When stored jpegs are compressed and when open they become un-compressed. Try saving an opened jpeg as .tiff and see how big it is. .tiff files are not compressed.

I have managed to increase a file size from 643kb to 11.3MB simply by enlarging the photo in Photoshop. Increase the image by 5% and it will slightly increase in size but not lose much quality, repeat this action until you get the file size required. Doing it in 20% increases will lose more quality of the picture. I''d suggest ''recording the action'' in photoshop to make it quicker. My image of 643kb now hangs on my living room wall measuring 24"x32" using the above method. Hope this helps.

Adpooler. It sounds as though you are shooting at a fairly low image size and/or low quality (high compression), presumably to cram as many photos as possible onto the card. It really is better to shoot at the maximum image size and quality that your camera will support. You will get much better images that way than by increasing the image size in Photoshop later.

MarkL - the image I increased was an old image from my first digital camera when I was still getting to grips with the basics of it. I now shoot using maximum file size like you mentioned.

Hi there, I would advice you to shoot in raw format rather than jpg, it will hold more information and be a bigger file size

Suman, having checked my files at lunchtime I find an 8MP camera with compressed files at 3MB in jpeg will give you 23.4MB when opened in photoshop. This means you should be ok as you are. Steve.

Dear Steve, Adpooler, Mark,

Thank you very much. I will open my images in photoshop and follow your advice.

This forum is wonderful.

Have a good Christmas and best wishes for the new year.

Suman

Suman, if you get this sorted please let me know. I am too being asked to submit a minimum of 18MB to Graphistudio for a story book and with 200 files I can''t see how I have the space! I must be missing something, my lab''s happy with JPEGs at 8MB!

I have just looked at this web page: http://www.albumart.com/textfiles/gs_digitalfiles.htm . The ''18MB'' refers to an opened file; i.e one that would save to an 18MB tif. It does not mean an 18Mb jpeg! When you compress the file to a jpeg the file size will be much less. Hope this clears up your problems. Happy Christmas. Mark
