Osim ako niste profesionalni fotograf, postoji mnogo puta kada je sjajna slika uništena jer je mutna! Bilo da se radi o tome što se nešto jako brzo kretalo ili zbog podrhtavanja fotoaparata, mutna slika je prilično beskorisna.

Međutim, postoji mnogo slučajeva kada jednostavno ne možete ponovno stvoriti trenutak uhvaćen u toj mutnoj slici i učiniti je jasnijom ili izoštriti sliku vrijedi pokušaja. Srećom, postoji tona alata koji se mogu koristiti za rješavanje ovog problema.

Softverski programi za poboljšanje slike poput Adobe Photoshopa^{(Adobe Photoshop)} imaju izvrsne alate koji pomažu da mutne slike budu oštre, ali nisu besplatni. U ovom postu govorit ću o nekoliko metoda u Photoshopu^(Photoshop) koje vam mogu pomoći da razmutite fotografiju. Ako vam je slika zaista važna, onda će vam Photoshop dati najbolje rezultate.

Osim toga, spomenut ću i nekoliko drugih programa koje možete koristiti u slučaju da na svom stroju nemate instaliran Adobe Photoshop . ^{(Adobe Photoshop)}Preskočite^(Skip) na prethodnu metodu 1 i 2 ako vas zanimaju drugi programi. Ostali programi koje spominjem također nisu besplatni jer sam otkrio da svi besplatni programi za uređivanje fotografija u osnovi imaju jednu opciju izoštravanja, koja gotovo uvijek radi užasno.

Programi u nastavku posebno su dizajnirani s prilagođenim algoritmima za stvaranje oštrijih slika uz najmanju količinu degradacije.

Photoshop metoda 1^{(Photoshop Method 1)} – korištenje dodatnog sloja^{(Extra Layer)}

Ova metoda je prilično jednostavna i radi vrlo dobro za izoštravanje slika. Na primjer, pogledajte ovu fotografiju s jednom stranom zamućenom, a drugom izoštrenom.

Pogledajte desnu (izoštrenu) i lijevu stranu. Vidite li razliku u drveću i u osobi koja silazi? Evo kako to učiniti.

Prvo otvorite sliku u Photoshopu^(Photoshop) i pritisnite CTRL + J da duplicirate pozadinski sloj. Obavezno^(Make) kliknite na Layer 1 na ploči slojeva .^(Layers)

Zatim idite na Filter , zatim Ostalo^(Other) i odaberite Visoki prolaz^{(High Pass)} . Što je viša vrijednost koju postavite, to će vaša slika postati oštrija. Međutim, ako ga postavite jako visoko, slika će postati zrnasta. Ja sam svoje postavio na 10 piksela.

Ne brinite ako vaša slika izgleda kao da je tamni ugljen po njoj, još nismo završili! Dok je novi sloj još uvijek odabran, postavite način miješanja na Hard Light i podesite neprozirnost^(Opacity) na ono što mislite da slika izgleda najbolje. Prema zadanim postavkama postavljena je na 100%, ali možete dobiti bolje rezultate na 50% ili nešto treće, pa se samo poigrajte s tom vrijednošću.

To je to! Vaša bi slika sada trebala izgledati mnogo oštrije! Nažalost, ako je vaša slika jako zamućena ili je zamućenost uzrokovana jako brzim pokretom, vjerojatno nećete vidjeti nikakvu veću razliku.

Najbolji rezultati su kada je slika jednostavno izvan fokusa jer je kamera fokusirala pogrešan objekt ili nešto slično. Evo slike prije i poslije koju sam testirao ovom metodom:

Photoshop metoda 2 ^{(Photoshop Method 2)} – Filter za smanjenje potresa^{(– Shake Reduction Filter)}

Gornja metoda bila je jednostavan način za izoštravanje fotografije u Photoshopu^(Photoshop) . Napredna metoda je korištenje novog filtera za smanjenje potresa^{(Shake Reduction Filter)} . Da biste počeli koristiti ovaj filtar, samo naprijed kliknite Filter , zatim Izoštri^(Sharpen) i zatim Smanjenje potresa^{(Shake Reduction)} .

Pojavit će se prozor sa slikom na lijevoj strani s nekoliko opcija s desne strane. Photoshop će automatski pokušati shvatiti koji dio slike treba pogledati kako bi ispravio zamućenje. Vidjet ćete ovaj odjeljak na slici kao točkaste linije.

To se zove trag zamućenja i prema zadanim postavkama postoji samo jedan. Trag zamućenja bi idealno trebao biti dio slike koja ima najveći kontrast rubova. Dakle, ako je jedan dio slike svijetao, a drugi dio taman, trag zamućenja trebao bi uključivati ​​rub. U gornjem primjeru, zadani okvir je oko njenog lica, što je u redu, ali nije idealno.

You can adjust the box by dragging the corners and changing the size. You can also click on the circle in the middle to move it around. If your image is really large, you can also create multiple blur traces in the case the blurring effect is different in different parts of the image. To create another blur trace, just click and drag to start drawing another box. I created two blur traces to see if the results would be better.

In my tests, I found that sometimes the default options resulted in better results than when I changed the blur traces. In other instances, I felt adjusting the blur traces made the images better, so you’ll have to really play around with all the options to get the best results.

Ovdje je konačna slika iz metode 2, za koju mislim da izgleda malo bolje od rezultata iz metode 1. Očito je daleko od idealne, ali mutne slike rijetko se mogu ponovno pretvoriti u kristalno jasne snimke.

Zamagljenost

Blurity je Windows ili Mac program koji je dizajniran samo za uklanjanje zamućenja fotografija. U mojim je testovima odradio izvrstan posao i mogu vidjeti zašto naplaćuju 79 dolara! Toliko se svakako isplati potrošiti samo ako vam slika zaista puno znači ili ako imate puno mutnih fotografija koje želite popraviti.

Također sam pokrenuo program kroz VirusTotal i ispao je čist, tako da se ne morate brinuti o špijunskom softveru itd. Jedina neugodna stvar u vezi s ovim programom je da nakon što ga instalirate, prisiljava vas da prođete kroz ovaj vodič koji MORATE^(MUST) dovršiti prije nego što stvarno počnete koristiti program.

U svakom slučaju, nakon što to prođete, samo kliknite gumb Otvori sliku^{(Open Image)} , a zatim kliknite bilo gdje na slici gdje postoji dobar primjer zamućenja na subjektu.

Nakon što odaberete regiju, samo kliknite na gumb Process i on će generirati pregled fiksne zamućene slike. Evo rezultata na mojoj probnoj slici s vodenim žigom i dalje na slici.

Popusti na vodeni žig, program zapravo radi vrlo dobar posao ispravljanja zamućenja na slici i to bolje jer košta prilično malo. Za dobre rezultate i nešto povoljniju cijenu pogledajte program u nastavku.

SmartDeblur

Još jedan dobar program dizajniran samo za mutne fotografije je SmartDeblur . Ovaj će vas koštati 49 dolara, ali opet, radi vrlo dobar posao. Nakon što preuzmete i instalirate program, morate kliknuti gumb Otvori^(Open) pri dnu kako biste odabrali svoju sliku.

Zatim možete podesiti nekoliko postavki poput veličine zamućenja^{(Blur Size)} ili vrste plave ( zamućenje izvan fokusa^{(Out of Focus)} ili Gaussovo^(Gaussian) zamućenje), ali preporučam da prvo koristite zadane postavke da vidite što program radi. Također možete odabrati regiju ako želite ili možete jednostavno kliknuti na Analiziraj zamućenje^{( Analyze Blur)} i analizirat će cijelu sliku.

Možda ćete nakon toga morati povećati opciju glatkoće jer sam otkrio da zadane postavke čine sliku prilično zrnastom. Evo mog rezultata za istu probnu sliku koristeći 100×100 za veličinu zamućenja i analizirajući cijelu sliku:

Dakle, imate nekoliko metoda za ispravljanje zamućenih slika pomoću softvera. Kao što sam spomenuo, svi besplatni alati koje sam isprobao radili su užasno i zato ih nisam ni spominjao. Ako imate bilo kakvih pitanja ili prijedloga, slobodno komentirajte. Uživati!

How to Make Blurry Pictures Clear

Unless you are a professional photographer, there are many times when a great picture іs ruined because it’s blurry! Whether it’s because something was moving really fast or because of camera shaking, a blurry piсture is pretty useless.

However, there are many times when you simply cannot recreate the moment caught in that blurry picture and making it clearer or sharpening the image is worth a shot. Luckily, there are a ton of tools that can be used to fix this problem.

Picture enhancement software programs like Adobe Photoshop have excellent tools to help make blurry pictures sharp, but aren’t free. In this post, I am going to talk about a couple of methods in Photoshop that can help you unblur a photograph. If the picture is really important to you, then Photoshop will give you the best results.

In addition, I’ll also mention a couple of other programs you can use in case you don’t have Adobe Photoshop installed on your machine. Skip down to past method 1 and 2 if you are interested in the other programs. The other programs I mention are also not free because I found that all free photo editing programs basically have a single sharpen option, which almost always perform terribly.

The programs below are specifically designed with custom algorithms to create sharper images with the least amount of degradation.

Photoshop Method 1 – Using an Extra Layer

This method is fairly simple and works very well for sharpening images. For example, take a look at this photo with one side blurred and the other sharpened.

Take a look at the right side (sharpened) and the left side. Can you see the difference in the trees and in the person walking down? Here’s how to do it.

First, open the image in Photoshop and press CTRL + J to duplicate the background layer. Make sure to click on Layer 1 in the Layers panel.

Next, go to Filter, then Other, and choose High Pass. The higher the value you set it to, the sharper your image will become. However, if you set it really high, the image will become grainy. I set mine to 10 pixels.

Don’t worry if your image looks like dark charcoal has been thrown all over it, we haven’t finished yet! With the new layer still selected, set the blending mode to Hard Light and adjust the Opacity to whatever you think makes the image look best. It’s set to 100% by default, but you may get better results at 50% or something else, so just play around with that value.

That’s it! Your image should now be much sharper looking! Unfortunately, if your image is very blurry or the blurriness is caused by really fast motion, you probably won’t see any major difference.

The best results are when the image is simply out of focus because the camera focused on the wrong object or something similar. Here is the before and after image that I tested using this method:

Photoshop Method 2 – Shake Reduction Filter

The above method was the simple way to sharpen a photo in Photoshop. The advanced method is to use the new Shake Reduction Filter. To start using this filter, go ahead and click on Filter, then Sharpen and then Shake Reduction.

A window will pop up with the image on the left with a few options on the right. Photoshop will automatically try to figure out which part of the image to look at in order to correct the blur. You’ll see this section on the image as dotted lines.

This is called a blur trace and there is only one by default. The blur trace should ideally be part of the image that has the most edge contrast. So if one part of the image is bright and another part is dark, the blur trace should include the edge. In the above example, the default box is around her face, which is OK, but not ideal.

You can adjust the box by dragging the corners and changing the size. You can also click on the circle in the middle to move it around. If your image is really large, you can also create multiple blur traces in the case the blurring effect is different in different parts of the image. To create another blur trace, just click and drag to start drawing another box. I created two blur traces to see if the results would be better.

In my tests, I found that sometimes the default options resulted in better results than when I changed the blur traces. In other instances, I felt adjusting the blur traces made the images better, so you’ll have to really play around with all the options to get the best results.

Here is the final image from method 2, which I think looks a little better than the results from method 1. It’s obviously far from ideal, but blurry images can rarely be turned into crystal clear shots again.

Blurity

Blurity is a Windows or Mac program that is designed only for de-blurring photos. In my tests, it did an excellent job and I can see why they charge $79! It’s definitely only worth spending that much if the image really means a lot to you or if you have a lot of blurry photos you want to fix.

I also ran the program through VirusTotal and it came out clean, so you don’t have to worry about any spyware, etc. The only annoying thing about this program is that after you install it, it forces you to go through this tutorial that you MUST complete before you can actually start using the program.

Anyway, once you get past that, just click the Open Image button and then click anywhere on the image where there is a good instance of blur on a subject.

Once you select the region, just click on the Process button and it will generate a preview of the fixed blurred image. Here is the result on my test image with the watermark still on the image.

Discounting the watermark, the program actually does a very good job of correcting the blur in the image and it better since it costs a quite a bit. For good results and a slightly cheaper price, check out the program below.

SmartDeblur

Another good program designed only for blurry photos is SmartDeblur. This one will set you back $49, but again, it does a very good job. Once you download and install the program, you have to click the Open button at the bottom to choose your image.

You can then adjust a couple of settings like Blur Size or the type of blue (Out of Focus blur or Gaussian blur), but I recommend just going with the defaults first to see what the program does. You can also select a region if you like or you can just click Analyze Blur and it will analyze the entire image.

You might have to increase the smoothness option afterwards because I found the default settings make the image pretty grainy. Here is my result for the same test image using 100×100 for blur size and analyzing the whole image:

So there you have a couple of methods to correct blurry images using software. As I mentioned, all the free tools I tried performed terribly and that’s why I didn’t even bother mentioning them. If you have any questions or suggestions, feel free to comment. Enjoy!
