Today, I'm here to make a late artifact in the place of death snapseed How to use .

Dry only .

More pictures .

I feel like I'll be killed by pictures ……

Promise me , For the sake of my hard work , When I send my circle of friends later , Try to make sure you don't send the original picture ?

I know you want to see the contrast map , Let's start with a group of town buildings .

This is the original

This is a revised picture

===================== I'm the dividing line for software profiles ===================

snapseed( The name of the Chinese version is “ It refers to a redrawing drawing ”) Is a very powerful mobile based image post Software . what PS More powerful ? crap .

To be exact ,snapseed Is a set of powerful and convenient in one of the late software .ps This kind of thing , First of all, it's only suitable for computers , It's not convenient to modify the circle of friends immediately after taking pictures with your mobile phone , And then there has to be a mouse , At the end of the run, it still takes up memory , Of course, the most important thing is , The technology content is relatively high , Most people don't have the patience to learn .

snapseed Is that , First , The interface is clean , There aren't so many messy buttons , Operate in one word , Shuang .

secondly , And the most important , Lossless photo quality . A lot of later software based on mobile phones will be foolishly default, you only need to view this picture on your phone , So the photo quality is compressed to fit the size of the phone screen , When it's transferred to the computer, it turns on , It's impossible to see …… and snapseed There is no such problem at all , This magical software is only responsible for modifying pictures , Not responsible for compression quality , So Apple users can choose airdrop Back and forth between the computer and the mobile phone , Non Apple users can use QQ File transfer between mobile phone and computer , Look at the photos on the computer and watch them on the mobile phone , There's not much difference in the effect .

Last , It's also my favorite ,snapseed A little surprise . I'll tell you later .

===================== I am the dividing line of the text =================

So let's see first Snapseed The basic function of :

that …… Sorry, I don't know what's wrong with it. I only found the English version on my mobile phone snapseed…… Anyway, there are not many new words. Let's make do with it , It's OK to look up the dictionary. There are not many new words …… Don't hit me . But there's a Chinese version ! Broadcast it again ! There is a Chinese version ! It's called a digraph ! Of course, if your mobile phone is OK, search directly snapseed It's also the Chinese version !

snapseed Only tools( Tools ) and filters( Filter ) There are two categories of functions , But these two kinds of functions are enough to cope with the vast majority of map revision needs .

First look at tools( Tools )

Tune Image( Adjust the picture ) This is the most basic function , It's about the same as PS The pull curve inside . It includes the following functions :

It's the brightness 、 atmosphere 、 Contrast 、 saturation 、 shadow 、 highlights 、 warm tones .

All the exposure problems and color temperature problems in the previous shooting , Both can pass Tune Image Get it done .

I know you're going to look at the contrast map :

Just through Tune Image, You can achieve this effect , So don't underestimate this most basic function .

Let's talk about it first. shadows( shadow ) and highlights( highlights ). When the exposure is uneven , That is, some places are very dark , Some places are especially bright , Promise me , Please be sure to try these two features . Increasing the value of the shadow can increase the brightness of the shadow part , And turn down the highlight value , Can reduce the brightness of the highlight part . The combination of these two functions can make the screen exposure more uniform , It is very helpful to show the details of the picture .

Use shadows And highlights When , Pay attention to brightness( brightness ) distinguish . Increasing the brightness value will increase the brightness of the whole picture , When the whole picture is underexposed , The brightness option is useful , But when part of the picture is exposed correctly and partially underexposed , Or when it's partially underexposed and partially overexposed , The only function of the brightness option is to make the overexposed parts more overexposed , Less exposed parts are less exposed .

Take a chestnut :

This photo has two problems with exposure , The first is that the overall exposure is slightly under exposed , That is, the brightness is not enough ; The second is that the arch is underexposed , It's almost black . There are two things to do at this time , The first is to improve the overall brightness , That is to use the brightness option to make the whole picture bright , Make the highlight part , That is, the church in the arch and the sky are exposed correctly , Then use the shadow option , Increase the exposure of the arch section . After that, we'll add some other treatments , You get the final picture .

In the processing of this picture , Exposure is the trickiest issue , And exposure issues , It's basically through brightness 、 Shadow and highlight three options to solve .

Contrast 、 Saturation and warm tones are easy to understand , Try it yourself and you can feel the obvious effect , About Tune Image, The last thing to say is this ambiance( atmosphere ) This amazing option .

So called atmosphere , Mysterious and mysterious , Through extensive use of , I think this function is basically equal to brightness 、 shadow 、 The combination of highlight and saturation , Very intelligent . It's suggested to take a picture and try it out , Feel a little bit of magical change in the picture as the number increases , You're bound to love this feature .

Most of the time, we will face the problem of local adjustment , There's something wrong with the exposure in one corner , There's not enough saturation in one corner , There's not enough contrast in one corner , Now Tune Image The functions are not helpful , The reason is simple , Move the whole thing .

Tune Image The functions of are all for the whole graph , So when there's a problem in one corner , It's about to sacrifice Selective( Local ) This big killer . Pinpoint the details , And it comes with transition function , The edges are not stiff , There's no need to worry about the scars .

Vignette( Fainting ) Its basic function is to change the brightness of the center and edge of the picture . In other words , Use vignette You can add dark or bright corners to your photos . Of course, usually we use the most , It's a dark corner .

The role of dark corners in photos , The focus of the audience is the visual guidance , Can play the role of highlighting the central content of the screen . All kinds of filters provided by various map revision software , Basically added a dark corner of the screen . There is also an advantage in focusing the viewer's attention on the center of the picture , It is to make the picture more concise by reducing the details , So more “ On the tall ”.

The last image with a pure white background is easy to see :

This is the original ️

This is the revised

Details( details ) There are two options , One is structure( structure ), Two is sharpening( Sharpness ).

There is no need to say more about sharpness , Let's look at the structure .

Use the structure option appropriately , Can make the details of the picture more prominent , More three-dimensional . Or talk with pictures :

Pay attention to the texture of the bricks in the modified picture , Obviously , Used “ structure ” After adjustment , The texture of the picture is clearer , More texture . Another set of contrast pictures :

Still pay attention to the texture of the brick , And the details of the character's arm .“ structure ” Options for improving the texture of the picture , It's very obvious and amazing . Pick a picture you like , Select the structure option , Pull the value to feel the change of the picture , You'll instantly fall in love with this feature .

in fact , This is one of the features I use most .

Let's talk about the tool category first , There are many other easy to use features , such as transform( deformation ), Can help create a wide-angle effect , Build long legs ; Another example healing( Stain repair ), It can help you get rid of redundant information points , Make the picture cleaner and simpler .

Let's talk about filter tools .

Filter tools are fun , There are many functions , A lot of times it can give you unexpected results .

Here's a brief introduction HDR Scape(HDR Scenery ) and Drama( drama )

HDR Landscape can intelligently adjust the exposure to color , Create a visual effect similar to color lead .

Upper figure :

To highlight the effect , The adjustment is a little exaggerated , In practice, you can adjust the transparency of the filter , Looking for the most appropriate effect .

Besides, Drama( drama )

This is the basis of the filter structure( structure ), Therefore, the texture of the image will become clear after use . In addition, it can increase the brightness around the main body of the picture , That is to create a halo for the subject in the picture .

Upper figure :

It's pretty obvious , After using the dramatic effect , Around the tableware , Especially the handle part , There's obviously a brighter circle , Make the subject of the photo more solid , It's also more prominent . Let's look at a few similar effects :

Dramatic effects are especially suitable for modifying photos that need to reflect the cloud , It helps to highlight the texture of the cloud , Make the shape of the cloud more prominent .

Upper figure :

Use more dramatic effects , You'll find the great surprise of photos .

In addition, there are many useful functions in the filter category , such as Lens Blur( Lens blur ), You can blur the background artificially , Make shallow depth of field . If you don't have a big aperture, you don't have to worry about not taking good photos of the background . Compared with the beautiful picture, the beauty of the virtual image ,snapseed The lens blur function has its own feathering effect , That is, the edges are soft , It belongs to gradient blur , There will never be a rigid transition from clarity to ambiguity , So the processed image looks very natural , The scar problem was solved perfectly .

Another example Vintage( Restoring ancient ways ), Not only does it offer a variety of retro filters , And equipped with adjustment function :

Give you more freedom to play . Your filter is up to you . Compared with many later stage software, although it provides numerous filter options, each one has a set value and is not allowed to be changed by the user ,snapseed Show greater respect for users' intelligence and aesthetics . Although the number of filters available is limited , But it gives users the freedom to adjust at will , The filter effect created is endless .

Besides Black & White( Black and white ) Provides a variety of black and white effects that can be adjusted by themselves ;Frames( Frame ) Offer up to 23 Kind of border options , And allows users to adjust the width of the border ;Glamour Glow( Glamour halo ) Help soften the picture , And support to adjust the softness freely 、 Saturation and color temperature ……

snapseed In terms of respecting the creativity of users , Go further than most later software . Good post Software , It must be a limited tool for you , Help you realize infinite ideas , Instead of giving you a lot of ideas , Let's just pick one and use it .

And I like snapseed The point of , It automatically retains every step of the user's modification process , And before it's finally saved in film , You can go back to any step at any time , You can also delete or adjust any intermediate effects at any time .

like this :

More Than This ,snapseed And there's a huge , It's a surprise that you can't predict the result of the movie : Repeat all the previous steps .

Let's take a concrete example : This is the original :

First , We need to rotate the cut to make the picture more neat and clean , And then use the drama function , Finally using Tune Image( Adjust the picture ) Fine tune the whole thing , Finally, use the detail function to enhance the texture of the picture , Got this picture :

In the top right corner of the 5 It means that it has been carried out 5 A step-by-step adjustment ), We click on the numbers 5, Every step that has been done will appear , Then click on the three dots in the upper right corner , choice Insert( Insert ), The steps that have been done will be copied automatically and appear above the existing steps , At this point, we click on any of the following steps , There will be different effects .

We go straight to the last step , Click on the top Details, All the steps go from dark to bright , All the modification steps below have been applied to the photo . At this point, we magically get this result :

Repeat the existing steps again , It's like this :
