RF BOOK-Project

I think it is about time that we finalise the format for this project. What is the size of photos? What is the font and size for the wordings?
 
Peter, can't give you the final size requirement for the photos yet - still waiting to hear back from LuLu to see if they can do a colour book in the larger size. Should know tomorrow.
 
Not a dumb question at all.

DPI stands for Dots Per Inch (Pixels by Inch) and is what determines print/presentation quality (on-screen or on paper).

It's basically how well the dots are 'packed together'.
On line you dont need anything over 72 DPI as thats the online presentation limit - but when you print a photo you need a higher DPI for your photo not to look all pixelated/jagged/edgy.

If you go to 'Image Size' in your photo editing tool of choice you will find something that looks like the screen shot below.
It shows 'Dimension' - which is pixel count in height and width,
It also shows 'Print size' - which is your pixel count converted to inches,
Finally it shows 'Resolution' - this is your DPI/PPI.

Now...what do you do if you open up your favorite two photos and realize - to your HORROR - that they were either saved at say 72 dpi or at a print size that is really tiny?

Well....two options...

a) You can extrapolate to 250-300 and depending on what you are going from and the type of image that MAY work well (basically you just overwrite the old value and type in what you WANT the dpi to be). I'd say save that version as a copy and look at it to see if you like it.

b) Re-scan. Either at home or have some photolab scan the film/prints for you.

There may be a more tech-savvy option 3 that I havent though of...

dumb question alert!

dpi of 300 means???

There's no dumb question, only dumb answers. :D

I'm pretty sure 300 DPI means 300 DPI printing, which is pretty much standard.

For a digital photo to appear sharp when printed, it must hold sufficient information. If you want a good 4x6 inches photo that doesn't square patches from pixelation, blurry, etc, then the file should be 1200x1800 pixels in size.

Now if you want 1200x1800 digital photo out of 24x36mm or 0.945x1.417 inch film, you need to scan the film at 1270 PPI.

DPI = dots per inch, normally used for printing
PPI = pixel per inch, normally used for scanning
 
Wayne - you are IN.

Please everyone remember to email me your email addresses - that you would not mind sharing with this group - to me at aperture (at) gmail.com

Thanks!
 
Just want to share. With PS you could 'enlarge' your photo from a 4R to 8R easily with bicubic. But the end result would be a softer image that could be touched up with a bit of USM. :)

so is the dpi determined at th time of scanning or when i save a photo after working on it (as in photoshop)?

ok, i think i have figured this one out myself.

all my scans were done at 72dpi cause i told the lab they could be low res for web use only.

so i need to pick my 2 shots and have them rescanned.

fyi,

i have made all the posts re. 'the book' sticky so we can find them easier.
and i 'stuck' the coffee & camera post also cause i have a feeling it will be around for awhile - sorta like a rite of passage.

News: Mike is also joining us (he is participant #15) and he brings a lot of experience from the world of newspapapers and editing. So Gene, Todd and Peter - be sure to hook up with Mike when you are drafting final PDF layout, covers and forewords!

Thanks again!
 
I added a very simple example of what kind of text blurb you can write for each photo you are submitting. The blurb can be longer or shorter but we should all keep the same bottom format:
Camera
Lens
Film

(C)

Open for suggestions on any of it ofcourse!!
Want to add filter used, etc? Maybe a 'Additional:' row?

Should we mention which scanner was used as well?
