Do you have a problem with your photos when you enlarge them? Do they appear fuzzy and out of focus? No doubt you have run into this from time to time. But what do you do when you need to enlarge your photo for a full page (12×12) photo or when you change the dpi and the photo becomes to small to be usable?
When I attended a Photoshop seminar many moons ago, I was told that you can actually enlarge a photo but only do so in 10% increments. i.e. take a:
The photo is 3.986×6.653″ at 72 dpi(original)
To use it on my layout I would need to resize to 100% at 300 dpi makes the photo considerable smaller at .957″x1.597″
But in order to make it large enough to use I would need to open the resize dialogue box change the pixel dimensions to percent 110. As you can see the new photo size will be 1.052×1.756″. (Just make sure your Resampling is set to Bicubic. To see it better just right click on photo and open in new window or tab. To learn more on Bicubic resampling in PSP take a look at About.com
I would suggest that you only do this a maximun of 5x as the photo will start looking fuzzy the more you enlarge it. The image below shows how Suzaan looks after increasing her five times (1.543×2.573″). And after adding unsharp mask which can help bring her back into focus.
Ten times with unsharp mask (2.487×4.143″). At this point adding the unsharp mask helps some, but not much.
If the photo you want to use cannot be enlarged by this method for a sharp, clean photo, then I suggest you enlarge it to the size you need and use a blending mode on it when you place it on your page. As in this case where I used two blending modes: Burn and Luminance. This technique also works well with out of focus pictures that you really want to use. Check out wikiHow for more blending tips.
Can you think of other ways you can use the resize and blend modes?
