how can I blow up and improve pixelation of lower resolution digital images?

Question

I use Mac so any external program would have to be compatible

Answer 1

If you have Adobe Photoshop

1) Open up Photoshop

2) Open up image

3) Select your crop tool
- Set width to 5"
- Set height yo 7" (vice versa if landscape photo)
- Set resoluton to 120 (a 72dpi image can be resampled to 12o dpi with little additional work)

4) Crop image

5) Click on Filters -> Sharpen -> Unsharp Mask
- Amount (45 - 55)%
- Radius (5 - 10) pixels
- Threshold (4 - 8) levels
Click ok

6) Click on the Channels on the Layers Palette

7) Select just the Blue channel

8) Click on Filters -> Blur -> Gaussian Blur
- Radius (5 - 10) pixels
Click Ok

9) Select the RGB channel

You'll have to experiment on the different settings as it will change per photo and what the photo is of. Also, contrast will play a big part in some of the percentages.

This will give you a nice, sharp 5x7 image that can be printed up to an 11x14 with keeping nice proportions and image sharpness

Answer 2

The best way to do this would be to open your image in Photoshop and increase the size by only 10% at a time. This is the easiest and safest way to increase and decrease your image without making it pixelated or blurry looking. Just keep in mind if you blow it up too much, no matter what process you use, it can get ugly.
You can also use the unsharp mask which works very well to shapren images. When increasing a low res image you would first want to go to image size and unclick resample. choose your image size then click back on resample and type in 300.

Answer 3

There is just one answer use adobe Photoshop.

There are a couple of ways you can do this.
1. Print the photo at the current resolution in a small print then scan it at a higher rate.

2. Save it at its current size at a higher rate and try to enlarge it.

The first way usually works the best.
