Pixel Enhance Software
So, in this post, I'd like to introduce you 10 advanced photo enhancer to help you edit & enhance an image on your Mac, PC, iPhone or other mobile phones. Fix 4 of the most common photo issues using our advanced image enhancement tools. A technique called adaptive exposure allows for our photo enhancer to surpass typical HDR effects. Rather than applying the effect to the entire image as a whole, HDR DLX separates the image into regions. This enables our photo editor to make micro adjustments.
Image editing programs like GIMP (GNU Image Manipulation Program) can give you resolution information and allow you to change the resolution of an image. One would change the resolution of an image particularly for printing purposes, because the quality of the print is dependent on the resolution of the image.
1. With GIMP open, go to File > Open and select an image
Tip: You may right-click and save the tiger image below to use it as a practice image.
2. Go to Image > Print Size
3. A Set Image Print Resolution dialog box will appear like the one pictured below.
If Print Size Width and Heights are not shown as inches, select the dropdown beside Height and select 'in'.
4. In the X and Y Resolution fields, type in your desired resolution.
You will notice that when you type a value into the Resolution field, the values of the document's width and height also change. This is because GIMP is changing only the resolution of the image and not adding any additional pixels (which is what happens when an image is resized). To change resolution we are NOT changing the number of pixels in the photo, but changing only how many of those pixels will be displayed per inch.

Congratulations! You have successfully changed the resolution of an image!
In this example, we had an image with a 300ppi resolution. I wanted to print this image in a professional publication and the image needed to be at least 600ppi.
Remember that the number of pixels in the image have stayed the same because we did not add or subtract any pixels to the image, only determined how many of those pixels to display per inch.
However, note that the Width and Height decreased by half when the Resolutions doubled. This means that in order to print at 600ppi and retain full-quality, I can print this image only as large as 5' x 3.33'.
What happens if we decrease our resolution?
As you may have guessed, our Width and Height doubled when we halved our Resolutions. Now my image will print larger, but the quality will be much lower.
What does it all mean?
It's a game of give and take!
We notice that the pixel dimensions never change. We started with an image at 3000 x 2000 pixels (px) and ended with the dimensions still being 3000 x 2000px. This is important to remember, because when we change resolution we are changing only how many pixels will be displayed per inch of the image, not how many pixels make up the image. Since we are not adding or subtracting any information (pixels) from our image, our image has to always balance out to its original 3000 x 2000 px. If we increase resolution then we must decrease from somewhere! Since the pixel dimensions cannot change, the only other place to decrease is our document size (width and height of image).
Here's the math to make it more clear: Sample Image is 3000 x 2000 px
600ppi: 3000 pixels / 600 pixels per inch = 5 inches

2000 pixels / 600 pixels per inch = 3.33 inches
300ppi: 3000 pixels / 300 pixels per inch = 10 inches
2000 pixels / 300 pixels per inch = 6.667 inches
150ppi: 3000 pixels / 150 pixels per inch = 20 inches
2000 pixels / 150 pixels per inch = 13.33 inches
72ppi: 3000 pixels / 72 pixels per inch = 41.67 inches
2000 pixels / 72 pixels per inch = 27.78 inches
How does resolution affect printing?
In this example, our image has been sent to print from a laser printer on standard 8.5 x 11 sheets of paper.
72ppi: The document size is so large that it cannot fit onto an 8.5 x 11 sheet and is clipped. The print quality is extremely low, leaving the image looking very blurry or 'soft'.
150ppi: The document size is still too large for the 8.5 x 11 sheet and the quality is mediocre and makes the image look acceptable, but isn't very desirable.
300ppi: The image almost fills up the entire sheet of paper and the print quality is very good with crisp, sharp details.
600ppi: The image is substantially smaller than the other files, but the quality is extremely high.
Which one to choose? The 72ppi and 150ppi images are too low of quality to produce a high-quality print, so they're out. The 300ppi and 600ppi images both looked very crisp, but the 600ppi image was way too small. For this example, the 300ppi image would work best because of it's larger print size and high quality.
The key to printing images is to find the best resolution that will produce both the size and quality you need.
Free Digital Camera Enhancer
'The whole process is so easy it's almost idiot proof.' Jumbo! Program of the Day
Note: Free DCE is a young (and free) brother of our commercial automatic enhancer and batch processor DCE AutoEnhance.
Free DCE does the hard job of noise reducing and automatic balance control for you. And it is free!
The program works best if you have bad light condition (indoor, shadows etc.) and your image is somehow off. So if some of your images are already fine, you won't see much difference. DCE makes very delicate changes..
One thing makes DCEnhancer different from other tools - reducing the noise and skin smoothing algorithm. It makes DCE ideal for making cool portraits and close-ups! |
First you have to find out the optimal settings for your camera.
There are just few sliders you will be changing more often:
Midtones - if your image is too dark or too bright
De-Noiser - to reduce noise and skin artifacts from the objects on the image.
Note: This software is intended for advanced users. Most of the sliders work in the default position. (As on the screen capture). You should gently change one of the sliders just little and then see the effects.
Once you find your optimal settings, it should work on most of your images from the same camera.
And you will always find images where it doesn't work..
