I was also shaking my head before your comment. Obviously people would rather do things right the first time, but circumstances and situation can change involuntarily and all people can do is make the best of those situations by coming up with work arounds. I must really spend some time learning how to operate the Photoshop I purchased some time ago.
I generally just resize photos by using Picasa3 for cropping and such. I have only ever used Photshop to re-size images. But only to a certain extent. When you start with a low-rez image it can only be sized up to a certain extent. You will see the resolution change as you mess with the pixel size. This is splendid stuff. Can you please suggest some free Photoshop plugins to simplify photo manipulation?
Nice article thanks for sharing. You could also consider using Photoshop, make the image a smart object, enlarge the canvas then scale the image to fit.
Remember that every time you open, edit, then save a. Is your target audience composed entirely of urban dwellers with access to fast broadband, who only visit your site while at home? Does your visitor-base have smart phones? Do you want to support a mobile experience? Then guess again.
Guys, there is no way you can enlarge or shrink a pixel. Pixel size is relative. You can only add or subtract pixels. Very nice and useful tips for resizing images. Resizing of images is a very common day to day activity of bloggers while adding photos to blog posts. I love this site and a lot of your posts have been very helpful. There are plenty of other resampling options in Photoshop. Thanks for choosing to leave a comment.

Each of these pixels is mapped to a fixed location on the image, hence the name Bitmap. Here is how to use this method in most common image editing software. Now you can export this file by saving it as a web image. Here is how to make small images larger in Gimp without losing quality.
Irfanview will now resize the image, which you can then save to your computer. Thanks Giorgio. Hello how do you make your mobile Nokia phone photos bigger to download on a shirt. Thank you! Hi Team, I am glad to have found my solution on this site.
Happy me Thank you once again. I have been looking for a resize plug in on photoshop! I have two questions: 1. Try this: 1. Open the file you want to resize — in this case you want to downsize. While in this file, hit Edit — Copy. Go to the new file and hit Edit — Paste. The 72ppi and ppi images are too low of quality to produce a high-quality print, so they're out. The ppi and ppi images both looked very crisp, but the ppi image was way too small.
For this example, the ppi 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. Web images work differently than printed images.
With printed images, we must pay close attention to resolution to ensure we get a high-quality print. For web images, we must focus on the pixel dimensions. Look at the two images below - one is ppi and the other is 72ppi. Pixel Dimensions x ; Resolution ppi. Pixel Dimensions x ; Resolution 72ppi. Both of these images display at the exact same size even though their resolution varies. This is because the pixel dimensions are what really matter when working with web images.
Notice that the pixel dimensions of each image are the same and therefore both images will display at the same size even though they have differing resolutions. University of Michigan Library Research Guides.
Ask a Librarian. Focuses on many common image questions in regards to image resolutions, resizing images, file types, vector and raster images, scanning, saving and more. Home Raster vs. What is Resizing?
PPI Pixels Per Inch refers display resolution, or, how many individual pixels are displayed in one inch of a digital image. If the detail was never present it can't be replaced. There are ways to increase the number of pixels whilst minimizing artifacts an example being fractal based image resizing.
These methods are useful when you need to print large without seeing pixel artifacts. But the results are nothing like what you'd get with an image that was higher resolution to start with. Resizing can increase pixel count if you want, but in general it cannot increase the amount of detail. Though in some situations upscaling is necessary for example, if you want to combine two images.
Use Sinc Lanczos3 interpolation when upscaling the image in Gimp. Even more, resizing usually leads to loss of image sharpness even if you downsize the image. Some resizing algorithms are better at keeping the image sharp, but are more likely to produce resizing artifacts.
Usually, you would need to sharpen e. Cubic interpolation is usually working well for downscaling. If you mean pixel density as points per inch, and resize as an operation to change the number of pixels in the image, then you can change the pixel density freely it affects only the size and the quality of the print , but it doesn't affect the quality of the resized image which depends mostly on what algorithm you use to resize, whether you upscale or downscale, and how much you resize.
However, it is possible to increase the amount of detail and resolution of the image, if you have a stack of almost identical images with small shifts with respect one another.
There is a technique known as super resolution. It is pretty advanced, and, as far as I know, it is not yet available in popular photographic software. But there are quite a lot of papers about it and research-grade code which can do it. Scaling algorithms have sophisticated ways of inventing pixels, called interpolation, but without more data, those added pixels cannot increase image details.
Clever algorithms may look slightly better than dump ones by adding pixels with more local contrast but that is it. Yes, it's possible to upsize an image. The most common application used for such work is Genuine Fractals which I see has now been renamed to Perfect Resize. It can be used as a standalone application or as a Photoshop plugin. The software will enlarge and then interpolate to fill in the "missing" pixels.
The company has some complex fractal algorithms that work pretty well. They offer a free trial Windows or OS X. It's not quite clear from your question what you mean by "resolution", as the term is often used to describe two not quite related things. Image size in pixels - i. This parameter describes how much information an image can contain - i. There are algorithms using fractals, wavelets etc.
Obviously, this trickery only works for a limited range of up-scaling. So, for example, if you shot an image at x physical pixels, there's absolutely no way to make it look as if it was shot at x pixels. This parameter is just a number recorded somewhere in image's metadata which controls how the image should be scaled when reproduced on a physical medium paper or screen. As a result, it controls the size of an image when printed or even, I'd say, the default size as you can easily change the image's dimensions in a publishing program, for example.
