Okay, I want to make a calendar using Cafepress.com. They tell me that for their large calendar, pictures need to be 3500x2300, with a dpi of 200. I am having a hard time finding a camera that saves pictures that large. :eek:

Is there an editing program that could help? Is there a way to increase the size without making it blurry? Someone I know told me this:

the photo has to be clear & preferably set on the highest/finest setting your camera has.

I can edit mine using Corel Photo-Paint. I just reset the DPI if I need to & then crop & resize the photo to whatever size I want. Usually need to sharpen the photo a bit after doing that.

And yes, the photos have a copy made to the correct size and dpi!
Would this really work well enough for a photo for a calendar?

Yes .. You can increase the pixel size ..
But it'll still only look as good as the original picture ... when standing father away.

I'd recommend using a nearest pixel algorithm for the resizing in this application ..
and maybe saving the Image as a gif file.

There are several free "viewer/editors" ..
Once upon a time, I saw one that had a nearest pixel resizer .. But I can't remember which one it was.
Anyone ???

If you can get me a Copy ... and are on a high speed net ...
I can send you back a resized copy ... done this way.
Send me a PM if you need my Email address.
The picture(s) will be too large to attach here.

Nearest pixel is usually referred to as nearest neighbor, and almost any program is capable of that. Some programs like Irfanview refer to it as resize rather than resample. It is faster than a resample method, but most consider it of lower quality. The biggest advantage other than speed is that you don’t usually require as much sharpening after a simple nearest neighbor resize.

Unless you use sophisticated filters like Genuine Fractals or Alien Skin Blow Up, you can’t usually do better than the Lanczos resample filter in the freeware Irfanview IMO. Or Bicubic in most good image editors.

The advice you got is accurate. You need to crop, resample and sharpen.

3500x2300 is pretty close to 3:2 but not exactly. Most smaller digital cameras give you a 4:3 ratio at best quality. In any case you have to crop to the right proportions before doing the resample. If you crop and resample to 3500 X 2300 at 200 PPI you get 17.5 X 11.5 image size. I would guess that is what the calendar requires. You can do all of that in Irfanview, but it is easier in an image editor like Photoshop or Elements.

The image will look great from a 7Mp or higher camera as there will be very little resample up to that size. Even a 5 or 6Mp should look quite good with a good resample and sharpening.

Glad you know what I meant .. not what I said. :)
Now that I think about this ... Laura probably has photos instead of Text like on a Calender.
This changes everything .. back to the "normal" way of doing things.

I've volunteered to help .. This'll probably take more than a simple freeware editor.

You would need a 9.18 Megapixel or so camera to get a picture that would not need to be resampled to a higher resolution. I found a UK site that reviewed few 10 Megapixel cameras that will give you pictures that you can crop a bit to exactly 3500 X 2300 pixels. How big is your wallet? :eek: :eek:

Mine's rather miniscule, actually. :p

Thanks, Noyb! I've sent you an email!
