I have a question about resizing photos for a challenge to make them bigger! I see the Photoshop help but I don't have that. In fact I don't have anything! I have Iphoto, so I really don't know how to make a photo bigger but not to big! It's either to big or to small there is no in between! Which is starting to make me mad! Well if you know how to do this please tell me!

Oh one more thing, if I didn't put this topic in the right place tell me and I will move it!

I think that IPhoto has no way to remove the sidecar files like exif ect that it keeps with the images. I get the image looking right in iPhoto, then move it to Graphic Converter. I can then resize it and strip off the fluff files for the challenges.

Kirbic walked me thru the process when I was learning how to do it.
I think you will find Graphic Converter bundled with your Mac in Applications. You can do a lot more with an image with G C than in iPhoto.
Hope that this helps.
To get an image from iPhoto to G C, open G C then close the pop up boxes that come up. I think "Cancel" will do that. That will leave the G C icon in the dock. Drag the photo from iPhoto to the icon in the dock, and it will open in G C.

There are many photo editing programs that will let you resize a photo. However, most are geared to makeing the photo smaller, not larger.

The biggest problem with making a photo larger is the deterioration of the image. The software cannot add details, so at the basic level it more or less multiplies the pixels to get the larger size. If you take it very far, things get jaggy and blocky looking. Anything beyond a very minor enlargement, the image gets soft.

With a D40 you have much more than enough resolution for a 640 pixel image. If you are needing to crop down to a size that is much below 640, you might want to consider reshooting with a larger lens, or get closer to the subject if possible.

Resizing upwards would be a last choice desperation move.

With iPhoto, you can make a new file in Finder, and in iPhoto, choose File-Export, and use the pop up window to make it jpg, and use custom to set the max size. The largest size for DPC challenges is the 720 pixels max, and 200 Kb file size, so why would you want to enlarge the shot from your D40?
If you export to the new file using the "medium" size setting in the popup, the images will be 640 pix on the longest side, just right for most of the challenges. I usually upload for my portfolio that way, and the file size is generally from 32 to 50 Mb.
For the challenges, I use G C to be able to set the file size to near the max allowed for the challenge.

Where is G C? I checked in my apps. and it was not in there! >_<

Any other suggestions?

How long should the export take?

I shoot jpg 12meg, the jpg files are about 4 meg each with the Fuji S3's. It takes about 4 or 5 sec to do the export. In iPhoto, select the image you want to export, then choose File at the top bar, and choose Export in the drop down. It will then ask you about size and file type (jpg for DPC photos) and the next pop up will ask where you want to send the file. It should only take a couple of sec unless you are trying to export a raw image.
I am using a 4 year old G5 Power Mac, so maybe they don't put Graphic Converter in the newer ones when they ship them.

Something must be holding up the export. I exported one to see how long it took at medium, and it took less than 2 seconds. This is a 1.8 Ghz machine, so your newer one should do the export in less than a sec.

I would highly recommend downloading and learning Gimp, a freeware photo editing software with a lot of power, versatility, and option.

Also, most importantly, it has a feature that allows you to save your images for web viewing, much like Photoshop.

*EDIT* err.. Gimp, not The Gimp. I watched Pulp Fiction recently.

*EDIT #2* Oh.. duh, a Mac. *smacks head*
