Im making an A5 Version (148 x 210) guidebook with Adobe Indesign and have now come to the bit where I need to add photos and topos. Some of my photos/images are from a point and shoot. Its also worth noting im on a steep learning curve here ...

Would I be right in thinking I need to only do the following?

1. Load up image/photo in Adobe Photoshop CS5.
2. Image > Image Size.
3. Uncheck the Resample Image tick box at the bottom.
4. Change to 300 pixels/inch. Click ok.
5. File > Save As > JPEG (Quality 10)

5. Open my Adobe Indesign document.
6. Drag and drop the JPEG onto the correct page in my book.
7. Resize the image with the corner toolbars to fit the image onto the page as required. Bit worried I might need to make the image/photo the right size for the A5 page in PP here!
8. Right click the image > Fitting > Fill Frame Proportionally.
9. As the image might look a bit fuzzy ----> Right click the image > Display Performance > High Quality Display.

Id go the whole hog and crank the quality up to the maximum 12. The only time I ever save images at anything other than max quality is for forum use. Everything else like flickr gets the full size&quality images, which with a 7D can mean up to 20mb files...

Why not just save as PNG or TIFF, rather than using a lossy format!

I started saving in .tiff but they were jumping from 2-4mb (size 10) to 50mb! That said space isnt an issue apart from when I try to transport it all to the printers :)

Advice taken. Ill be saving as a .tiff from now on. unless .png is a better option?

You shouoldnt need to resize the images at all in Photoshop, you should be able to resize them imported straight into InDesign to maintain print quality.

Theres no point resizing the source file or converting it to a TIFF when its already a JPEG.

Agree, Im not sure how indesign re-sizes though, but expect its fairly intelligent?

Ah right ... this is news to me then. Im basically acting on advice as shown here from the previous author:
QuoteJust to share a few problems ive encounterd after meeting with the pinters for the winter guide. As well as width and height; photos need to be sized at 300 DPI. With this finer resolution any lines you draw on will be less likely to pixellate (there are couple of horrible examples of pixellation in the last guide where lines were drawn on 72 or 96 DPI images and you can see the 'steps'). Whatever images you send to the printer will need to be at this resolution anyway for the printing process ...

I am saving the final images, to send to the printer, as a 300 DPI .TIFF because that's the resolution that the printing processes work to. You'll find that working at 300 DPI on screen will mean you see what you are going to get. Computer resolution and print resolution are different. Just as well to know in advance.

Also just to clarify ... im originally taking the photos and have to then add some lines to them using Abode Illustrator. A lot of the files are actually .NEF (i.e. RAW files) so I can save them as anything I like. I  guess .png or .tiff would be better than .jpeg?

If thats the the case then yes, save as TIFF and change the resolution PPI to 300 (this is nothing to do with resampling, which only affects the quality of resizing adjustments via anti-aliasing, etc. Always keep resampling set to bicubic sharper for best quality)

Serious

Most pictures should print to at least 300 pixels/inch anyway if you are reducing their size to sub A4. Remember to print a test just to make sure if its going to an outside printer. This should only be an issue if you are using an incredibly old or bad image source.

Cheers for the help folks. So to sum up I should let Abode In-Design sort it to 300 dpi? Which it somehow does on it's own.

My other problem is resizing images once they are placed into Abode In-Design. I've got some good high res photos that seem to either distort or loose quality if I make them fit the page. Does the "only drag a corner icon" apply here? Is there a way to vector them or something? I'm deffo going to need to make these images fit into my A5 page.

I've not used In Design really so can't give you specifics, but if it's like the other software in the suite there should be a tool that will allow you to specify a width/height resize in percentages so if you are corner dragging you can just click on the tool to make sure the width/height ratio matches so the images aren't distorted. They shouldn't lose quality though, perhaps it just looks that way because its a preview?
