How to Use Windows 10’s Built-In Photos App

How to Use Windows 10’s Built-In Photos App

As a fairly versatile operating system, Windows has always had ways of browsing and viewing photos. But with Windows 10, Microsoft decided to try and mash browsing, organizing, and viewing all together in one application, with some basic editing to boot. The result, the innocuously-titles “Photos” app, can be less than intuitive.

Here are all the different things you can do with the Photos app… assuming you want to.

Starting Photos and Setting Defaults

Starting up the Photos app is pretty simple: for most new machines and fresh installations of Windows 10, it’s already in the Start menu as a big tile. Even if it’s not, just press “Start” and then begin typing “photos” to bring it up quickly via search.

The Photos app is already set up as the default image viewer in Windows 10. If something else has taken over those duties, it’s easy to reset the status quo: press the “Start” button, type “default,” then click the first search result, “Default app settings.” Under “Photo viewer,” click the “Photos” icon.

Browsing Photos

The Photos app offers three different interfaces when looking for photos: Collection, Album, and Folders. You can choose any of the three at any time by clicking the relevant tab, above the main interface and below the “Photos” application label.

“Collection” is a view of your most recent photos and screenshots, displayed in reverse order by date. “Albums” is a series of automatically-created photo albums, organized according to the Photo app’s internal logic, though you can add your own and remove or add photos to existing albums.

And “Folders” is merely a tab for all of the photos on your machine in specific folders—your OneDrive photo folder and your assigned “Pictures” folder in Windows, by default. To add folders to this view, click “Choose where to look” to go to the Photos Settings page, then click “Add a folder” to manually select one in Windows Explorer.

Within the main viewer of “Collection,” and in the nested album or photo viewers of the other tabs, a series of controls appear on the upper-right portion of the interface. These allow you to select multiple items for a specific action like copying, printing, or adding to a specific album, or to start a slideshow, refresh the current file view, or import from a camera or mobile device. Contextual items in the Album view allow you to edit the name of the album or change the cover photo.

To navigate backwards through the Photos interface, click the left-pointing arrow in very top upper-left of the window, or press the Esc or Backspace keys at any time.

Using the Photo Viewer Interface

When you finally get down to an individual photo, the interface goes completely black and dedicates the maximum length or width of the window. If you’re using mouse navigation, scrolling up or down will advance or retreat in the current collection, album, or folder. Hold down the “Ctrl” button on your keyboard to turn the mouse wheel into zoom or retract controls.

On the bottom of the interface, manual arrow controls to go forward or back in the album are on either side of an “add to album” button and a Delete button. You can use the keyboard for both actions: Ctrl+D to add it to a specific album via a pop-up menu, or simply press the Delete button. If you press “Delete” again, the image will be removed both from the album/collection/folder in the Photos app, and the file itself will be deleted in Windows Explorer and sent to the Recycling Bin. Tread carefully.

The top controls are labelled, and fairly self-explanatory. The “Share” button will open Windows 10’s share menu, allowing the user to send the file via email, copy it via Windows’ standard copy and paste function, or open and share it directly in any compatible Windows Store app. Zoom opens a manual slider to zoom in and out—remember that you can do this much faster by holding the Ctrl button and using the mouse wheel. “Slideshow” will begin a full-screen slideshow of the current album, collection, or folder.

The “Draw” command allows you to write on the image, with a selection of pen and eraser tools that appear contextually. It’s mainly intended for pen-enabled devices like the Microsoft Surface. You can double-click on any of the tools in the upper bar to select color and width. Note that the drawings can be erased with the Eraser tool, but after you click “save” (the floppy disk icon) and see the “Letting your Ink Dry,” the original file for this photo is saved over. Don’t click “save” on a photo unless you have it backed up somewhere, or you’re willing to lose the original.

“Edit” opens the photo editor, which we’ll cover in the next section. “Rotate” will rotate the image clockwise; if you hit it by accident, just click it again three more times to return the photo to its original orientation. At any time you can right-click on the image itself to open up most of these items in a menu.

Using the Built-In Photo Editor

The editor in Photos isn’t exactly incredible, but it can handle some light cropping and adjusting if nothing else is available. On the main interface, using the + and – buttons will zoom in and out, which can also be done with the mouse wheel (no Ctrl button necessary). Click and drag any part of the image to move it around, or click the “Actual size” button (the box with corners in the lower-right) to see the whole photo maximized horizontally or vertically.

The Crop and Rotate Tool

How to Use Windows 10’s Built-In Photos App

The “Crop and rotate” button is the most prominent tool, as it’s visible at all times. Click it to open a dedicated cropping UI. You can click and drag the circles on the corner to manually select a cropping box, or click the “Aspect ratio” button to choose a standard size. This is quite useful if you want your image to be viewed on semi-standardized devices, like a smartphone or TV (16:9), iPad (4:3), or a corporate projector (usually 4:3 as well). The “Flip” button will flip the image horizontally, but not vertically, and the “Rotate” button will spin it clockwise by 90 degrees. To get a non-square rotation, click the circle beside the right-hand menu and slide it up or down. When  you’re finished, click “Done” to return to the full Edit interface.

The Enhance Tab

How to Use Windows 10’s Built-In Photos App

Right below the Crop button are two tabs, “Enhance” and “Adjust.” Let’s look at Enhance first. The “Enhance your photo” tool is an all-in-one slider: click and  drag the slider from left to right to apply automatically-selected filters to “enhance” the image, according to the Photo app. You can stop it at any point along the axis. Generally this tool brightens up an image, smooths out shadows and highlights, makes a more ideal contrast, and just generally makes things look clearer.

The rest of the “filters” on the Enhance tab work the same way: click one of the filters, then click the slider beneath “Enhance your photo” to apply the effect, with a left-to-right strength of 0 to 100. You can apply multiple effects by clicking on a new one and then adjusting the slider—rinse and repeat. When you’re done, click the “Adjust” tab.

The Adjust Tab

The controls for this page are fairly similar, but you can adjust multiple factor at once. The “Light” sliders adjust the contrast, exposure, highlights, and shadows of the image, with the master “Light” slider being a combination of all four. The “Color” slider handles saturation, with 0 reducing the image to greyscale and 100 making it overly vibrant. More fine controls can be applied with the Tint and Warmth sliders.

The separate “Clarity” slider will outline specific edges with darkened shadows or blend them into the background, and the “Vignette” slider will add a white (left) or black (right) vignette effect to the photo.

Finally, the Red Eye tool will let you click on a subject’s eyes to remove the red glare from a camera flash, and the “Spot Fix” tool will let you click and drag around a specific area to obscure fine details. It’s good removing acne and other blemishes.

Saving Your Edits

When you’ve edited your image to your liking, you have two options: “Save” will overwrite the original image file (not recommended), or “Save a copy” will let you save the edited version to a folder in Windows Explorer. The second is obviously better, unless you’re absolutely sure you don’t want the original. At any time during editing, you can click “Undo all” to return to the original image and start over.

It’s no Photoshop, but it’ll get a simple crop or adjustment done in a pinch.

Find and Rid of Duplicate Images on your Computer

You can have duplicate images on your computer for three reasons:

1. You transferred a set of pictures from the digital camera to your computer but did not erase them from the camera. Thus when you re-connected the camera, they got copied again to your hard drive but in a different location.

2. You made some minor edits to a picture – let’s say you cropped it or fixed the rotation – and your image editing program saved the edited image as well as the original picture.

3. You may also have images on your computer that are “loose duplicates” of each other.  That means the images are mostly identical except for very minor variations – often happens when you capture multiple frames in quick succession.



HOW TO DELETE DUPLICATE IMAGES

If you are only looking to find and remove images that are “exact” duplicates of each other, Google’s Picasa desktop software could be a good solution. Just import all your picture folders into Picasa and then choose Tools –> Experimental –> Show Duplicate Files to see a list of potential duplicates.

While removing duplicate images with Picasa, please remember that the software will list all copies that are found of an image including the original one. You therefore need to keep one of these copies and delete the rest as demonstrated in the above screencast.



Alternatively, create a separate folder that’s not included in Picasa and move all the potential duplicate photographs to that folder instead of deleting them.


FIND AND DELETE SIMILAR IMAGES (NOT EXACTLY DUPLICATES)

Now Picasa is a good solution for deleting identical duplicates but your disk may also be storing have pictures that look similar visually but may differ as far as pixels or bytes are considered. Such files won’t be recognized by Picasa as duplicates but VisiPic, a tiny utility for Windows, can come really handy here.

To get started, launch the program and click File – > Add Folder to add folder(s) that you want to scan for duplicates. Then slide the Filter to somewhere between “Strict” and “Basic” so that program may group images that are similar or only slightly different. Hit play to begin scanning for duplicates.

To eliminate the duplicates, just move your mouse over the thumbnails and left-click the pictures you want to delete. They’ll be marked with a recycle bin icon and you may then either choose “Delete” or even “Move” to transfer them to a separate folder.

The tool is also smart enough to auto-select images for deletion that either have lower resolution or lower file-size than the original image.

How to Remove Personal Information from your Digital Photos



This iconic Situation Room photograph, captured at the White House, has now been viewed more the 2.5 million times on the web. There’s little information available about the photograph but if you download the full-size version, you can get details about the camera model, the camera  settings and even the software that were used to edit this picture before it was published online.

This information is stored in every digital image, in the form of EXIF tags, and you can extract it using Windows Explorer or with the help of even the most basic image editing software. In the case of mobile phones, your pictures may even include location information thus giving others an idea of the exact geographic coordinates where that shot was taken.


HOW TO REMOVE CAMERA AND GPS DATA?

If you are planning to share your personal photographs over email or on a public website (like Tumblr), it may sometimes make sense to remove the camera data and the location information from the images before putting them online.

There’s a free Windows utility called QuickFix that can help you here. Simply drag-n-drop the photographs in the QuickFix window and click the Clean Metadata button to remove all identifiable information from the photographs. It creates a new copy and won’t overwrite your original photographs.

QuickFix will not only delete the EXIF data and the GPS location information from your photographs but also the IPTC and XMP tags that may have added by the photo editing application.

Microsoft also offers a free utility called Pro Photo Tools that you may use to edit as well as delete common metadata from digital photographs including the GPS location.

AN ALTERNATIVE WAY TO REMOVE EXIF INFORMATION

If the photographs are in one folder, you can easily remove the EXIF data from one or more of these photographs using Windows Explorer itself without requiring any additional software.

Select all the images files, right click and choose Properties. Now hit the Details tab and click on the “Remove Properties and Personal Information” link. The next screen will give you an option to remove the various metadata that is embedded inside the pictures. Simple.

Online Tool Crops your Images “Intelligently”


Cropp is an online tool that will intelligently crop and/or resize your images in the browser without requiring any software. You can use the tool to crop a single picture or upload multiple images (max 5) and it will crop /resize them all to the desired sizes in a batch.

This is obviously a crowded field – search for “crop resize images” in Google and you’ll find dozens of similar web apps that do cropping and much more –   but there are few unique features in Cropp that you’ll probably like.

MANY-TO-MANY CROPPING

One, Cropp is probably the only online app that does many-to-many cropping – you can upload multiple pictures, select multiple outputs sizes and it will provide you all the cropped versions in a downloadable zip file.

The other advantage is that Cropp algorithms will automatically try to preserve the most interesting parts of a picture in the cropped version (handy when you are trying to create small thumbnails). And if you aren’t happy with the final output, you can always adjust the crop marquee manually to get the desired result.

An Impressive Web-based App for Photos Editing

Today we chanced upon an interesting web-based image editor that’s fast, the UI is beautiful with several useful features. It’s called Picozu.



While Picnik and PicMonkey are purely photo editing apps meaning you can use them to edit your existing images, Picozu lets you both edit and create new images from scratch. Picozu is written in pure HTML5 and CSS3 and requires no Flash or other plugins.

To get started, you can upload load images from your computer or you can directly import photos from your other cloud-based accounts like SkyDrive, Google Drive, Facebook or Dropbox. Alternatively, you may fire your webcam and capture images direclty inside Picozu.

The app offers a layer-based editing workflow seen in editing software like Photoshop or GIMP. There are dozens of filters and image-effects to give your photos a distinct look. Or you can use the regular tools and brushes to manually touch your photos.

Their Firefox add-on takes screen captures and imports them into Picozu for editing. There are also built-in tools for creating photo collages and posters.

How to Change the Date of your Digital Photographs

Most image editing software, Picasa and iPhoto included, allow you corect the data and time of photographs imported from a digital camera or a smartphone. You can import your digital photos in the software and select the ones that need to be fixed.

In the case of Picasa, choose Tools -> Adjust Date & Time and select a new date for your photos. This will change the “Date Picture Taken” field in the EXIF data of you picturs. Similarly, iPhoto users can choose Photos -> Adjust Date & Time to set the selected photos to a particular date and time.

ther's a little-known comand line utilitly called ExifTool for such operations since it is much more versatile. To get started, download the ExifTool executable and extract the zip file to your desktop. Now rename the exiftool(-k).exe utility to exiftool.exe and we are all set to adjust the date and time of our photographs.

Unlike the iPhoto or Picasa software that simply set the date and time of a photograph to another time stamp, Exif Tool can “shift” the data and time values associated with a picture. For instance, if your camera’s time was off by 2 hours 30 minutes at the time of capture, you can use ExifTool to shift the time stamp of all your pictures only by that “off” duration.

The sytax is:

exiftool.exe "-DateTimeOriginal+=Y:M:D h:m:s" filename.jpg
For instance, if wish to shift the time of photographs by 5 hours and 30 minutes, the command would be:

exiftool.exe "-DateTimeOriginal+=0:0:0 5:30:0" filename.jpg
And if you wish to perform a negative shift by 1 day, the command would be:

exiftool.exe "-DateTimeOriginal-=0:1:0 0:0:0" filename.jpg
Please refer to this document for the exact syntax and other examples.


While other programs only modify the “Date Picture Taken” (DateTimeOriginal),, Exif Tool can also be used to modify other meta data include the “Date Modified” (ModifyDate) and “Date Created” (CreateDate) fields. The command would be:

exiftool.exe "-AllDates+=Y:M:D h:m:s" filename.jpg
Exif Tool makes a copy of your original photograph before updating the time stamp. The tool is free and available for Windows, Mac and Linux.

Clean Up your Whiteboard Pictures by Email

One little trick that will vastly improve the quality of your whiteboard pictures is available inside the manual settings of your cameraphone. Go to your camera’s manual settings, choose EV (Exposure Value) and add 1 or 2 “stops” (usually indicated by +2) before clicking the Capture button.

Then there’s a shell script that brightens and cleans up your whiteboard images using the popular ImageMagick library. It runs from the command line and all it needs is ImageMagick, a free image editing software that is available for Mac, Windows and Linux.

If you find it a hassle to remember commands, there’s an even easier way. Capture the whiteboard scribbles with your mobile camera and send the picture as an email attachment to the following email address.


Wait for a minute or two and you’ll get a prettier version of the whiteboard image, clean and legible and more optimized for printing. Here’s an example.

Before

After

Internally, the Unwhiteboard service uses the same ImageMagick command to clean up your Whiteboard captures but on their own server so you don’t have to install anything on your computer.
