How to Increase Resolution of Image?

Passionate Photographers like to pursue his image quality first, which also includes maximum sharpness, picture details, and resolution.  Most likely, you’ve thought at some point how to take high-resolution photos or upgrade the resolution of already taken images that you have (whether it is photographs or any digital pictures).  This article explains step-by-step how to quickly and easily increase resolution in common post-processing software.  It also includes a comparison of five popular options for upsampling images to find which one achieves the best results.

Note that this article approaches the subject of resolution primarily from the point of view of photography, although the final comparison between software options also includes a digital illustration component.

WHAT IS RESOLUTION?

In photography, resolution implies the amount of detailing your snapshot has. This focus is determined by factors such as precision, lens quality, and camera sensor pixel count.  If you print your picture, other factors also come into play – size, display medium, and print quality, and so on.

People use the term “resolution” to talk about more than just the level of detail in a photo.  It can also refer to more specific things like resolving lens power, pixels per inch in print, and total pixel count of your digital image.  That end-user is one of the most common and is also the focus of this article.

When photographers ask about increasing the resolution of an image, the pixel count is usually on their mind – turning something like a 200 × 200-pixel photo into 1000 × 1000 pixel photo (just to take arbitrary numbers).

If the clear image quality of your photo has not improved, it is certainly not enough to just add pixels.  Otherwise, why bother increasing resolution?  Unfortunately, it is not easy to get a good photo from a low-resolution original – but it is not impossible.  You can still get impressive results if you do things right, as shown below.

Increasing Resolution in Photoshop and other post-production software

Most major post-production software can increase the pixel count of an image.  However, this is not really a complex part.  The difficulty lies in achieving any meaningful extension (or even confusion) of the path.

Hopefully, you will not be surprised to hear that the CSI-level “enhancement” of a low-resolution thumbnail is only possible on television.  No matter how good your post-processing software is, you can only go to improve a picture with a lower resolution.  Depending on the software you use, sometimes the best-case scenario is creating a pixelated image, out-of-focus instead!

But this does not mean that the situation is hopeless.  This in fact further helps the resolution of a still image (here about pixel count) that is known as upsampling.  Personally, this is something I do when making large prints – over a meter / three feet.  It also helps as a last-ditch to improve an image that might otherwise be unusable.

If this sounds great to you, here’s what you need to know to increase the resolution using some common post-production software.

How to Upsample in Photoshop

It is very fast and easy to refine an image in Photoshop. You simply go to Image> Image Size, type in the pixel dimensions you want, and select the ablation method you prefer. (Hint: If you have Photoshop CC, the new “Protected Description 2.0” is what you should be choosing.

After you are done, you may want to sharpen the photo a bit, though it depends on the image. Above all, it is a quite a fast process.

Personally, this is the method I use to highlight a photo for printing. To be specific, I can usually uplift the photo to get a 300 PPI image (pixels per inch) in my chosen print size, because nothing overkill is overkill.

Using Dedicated Upsampling Software

Many photographers already own Photoshop, and not surprisingly, it is the most popular tool for capturing images.  Nevertheless, you will find many dedicated options for this task, especially on the market.  Historically, the most famous of these options was called the genus fractals.  It eventually changed the name to Perfect Resize, and now ON1, but it is still the same program under the hood.

Just because this standalone software does not mean it is the best. However nevertheless, if you do not have Photoshop CC, some of these dedicated resizing programs may be worth checking out.

Free Choice

With the many paid software options available, some free tools can do the same.  One of the most popular is open-source photography software known as GIMP, not only for upsmapping, but also for extensive photography work.  Upsampling in GIMP is a simple process for upsampling in Photoshop.  Click on Image> Scale Image and select your regeneration options, then consider sharpening the photo after the fact.

Apart from GIMP, there are other few websites that offer you images at no cost.  In addition, you can already have your own software with upsampling capabilities, such as Lightroom (which may prevent exports) without realizing it.  Before you pay for another product, it is worth checking what you already have.

What about its future Applications?

Some companies are already developing software that increases resolution by analyzing the scene and recognizing the elements within it – as opposed to “dumb” calculations like the nearest neighbor pixel values, which we usually have today.  Huge names like Google and Adobe are getting into this business, and we can apply these new technologies to some products long ago.  (With Adobe’s most recent Photoshop CC upsampling algorithm in the test below, we are already seeing clues as to how it will be in the future.)

Even so, these technologies never fully mature.  Some of them are limited-purpose algorithms, focusing only on a certain type of image, such that people’s faces are viewed from a certain angle.  Others are more general, such as Adobe’s, but not to the same level of specialized options.  And since most of them are not available yet, it is non-issue of anything.  Nevertheless, it will be exciting to keep an eye on whatever developments may happen!

Upsampling Software Comparisons

I thought it would be useful to test some of today’s most popular upsmapping software to see which options work best with increased resolution. I wanted to test both a picture and a digital illustration to see if there was a big difference. My way was to start with a 300 × 300 pixel version of each image, then expand each to 900 × 900 pixels.

Keep in mind that I have only tested two images for this comparison, and you may get slightly different results with some photos and your (or different amounts of unadulterated) photos. Nevertheless, this should give you a good idea of ​​the relative strengths of each software package for increased resolution.

Online Program: Photo Enlarger

Many of them require account or cost money, but some of them are free.

I tested all the free options I could find, and the best result that came out was that the most popular option “En Anglegger” also appeared

It actually worked surprisingly well – second-best on illustration and third on the landscape.

In particular, there is a good amount of detail in the river and grass without over-sharpness in landscape photos. The depiction of the elephant looks quite good.

Upsampling Software Ranking

When I went with this comparison with the expectation to see only about the minor difference that occurs between those two different software. Instead, it turns out that Photoshop CC’s updated algorithm is very clear and better than the other options already available in the market for both photography and digital illustrations.

I have rather made it clear that I am not that biggest fan of Adobe due to the reason that they no longer sell standalone versions on the top of their software but rather I absolutely had to give credit for what exactly is due. Whatever artificial intelligence juice has been used in preserve Details 2.0 algorithm that clearly works well.

As per my ranking allotment. Here is how I would rank each software’s attempt in increasing the resolution of a photograph from best to worst:

  • Adobe Photoshop CC, Preserve Details 2.0
  • ON1 Resize 2018
  • Photo Enlarger (online option)
  • GIMP
  • Adobe Photoshop, Bicubic Smoother

And further for the illustration:

  • Adobe Photoshop CC, Preserve Details 2.0
  • Photo Enlarger (online option)
  • ON1 Resize 2018
  • Adobe Photoshop, Bicubic Smoother
  • GIMP

Out of my interest, the two lists were almost similar but only having little shuffling. Probably, good upsampling software usually works better no matter what type of image you use to it.

Another thing surprising is that the quality of online options that is free such as photo enlarger that punches above its weight in image quality, even though nearly as many as advanced options are some of the other software there.  Since it is designed for the betterment of day to day work, only “Preserve Details of 2.0” of photoshop was beating it both the times and therefore algorithm is just on another level.

Increasing Resolution in the Field

The above comparison shows that if your photos do not have enough resolution, then all hope is not lost.

However, the best method (so far) for capturing high-quality photographs is to get more and more rights in the field. Start with a sharp photo and crop as little as possible.

First of all, you need to start with good photo technology if you want to get high-resolution images (going back to the original definition – the amount of detail

Use the tripod whenever possible, and make sure your shutter speed is fast enough to freeze at any speed (from your subject or by yourself if shooting handheld).

Focus properly on your subject, and do not use ISO too much. In short, learn the proper techniques for taking sharp pictures. However, if you want to take things one step further, it is also possible. Personally, if I feel a wave of inspiration when taking photographs, I sometimes try to capture as many high-resolution images as possible to print as much as possible.

This can easily be done by taking a panorama (mixing multiple photos at once) instead of one picture – potentially increasing your pixel count several times. There are also other ways to increase the resolution of an image in the field.

You can try to pay attention to stacking to artificially increase the depth of field (and to use the Sharper aperture along the way). Other photographers will take multiple photos of the same scene – not a panorama – and average in post-processing software to reduce noise and improve low-level detail.

Quite simply, you can easily find having many options available to you. But even if you don’t use any particular technique such as stitching panoramas or averaging multiple exposures, today any camera can capture high-resolution photos suitable for large prints. The earlier covered Upsampling technique is really useful but they are mainly intended for salvaging especially while having a low-resolution image that is printing larger than the normal.

Conclusion

Hopefully, this article helped you learn how to increase the resolution of your images properly, with top image quality and minimal pixelation. You certainly don’t need to upsample every photo you capture, but it’s a good step to take before making large prints. And, if you ever have a very low-resolution photo that you need to enlarge to the point of usability, you now know how to get it to where you want.
