Find Similar and Duplicate PSD Files

How to find similar or duplicate photo files – PSD- Photoshop Document Files (Adobe Photoshop)

Photoshop files can grow quite large and saving multiple versions of the same document can lead to huge waste of disk space. Having in mind that even simpler files can take up to 100 MB, a quantity of even 50 unused files will waste 5 GB of disk space. Visual Similarity Duplicate Image Finder provides support for over 100 popular image formats and also 300 RAW camera formats. This of course includes the popular *.psd file format.

While a standard duplicate finder can find exact duplicates, it will not help you in such situation where the images are slightly modified or converted to multiple formats. The Duplicate Photo Finder performs a real image analysis and can identify duplicate and similar photos even if they are edited and stored in various file formats. It is the only similarity tool that supports the complex PSD file format. There is a FREE demo of this low-cost tool available for download at the above link.

About Adobe Photoshop

Adobe Photoshop is a graphics editing program developed and published by Adobe Systems.

Adobe’s 2003 “Creative Suite” rebranding led to Adobe Photoshop 8’s renaming to Adobe Photoshop CS. Thus, Adobe Photoshop CS6 is the 13th major release of Adobe Photoshop. The CS rebranding also resulted in Adobe offering numerous software packages containing multiple Adobe programs for a reduced price. Adobe Photoshop is released in two editions: Adobe Photoshop, and Adobe Photoshop Extended, with the Extended having extra 3D image creation, motion graphics editing, and advanced image analysis features.[7] Adobe Photoshop Extended is included in all of Adobe’s Creative Suite offerings except Design Standard, which includes the Adobe Photoshop edition. However, in 2013, Adobe announced a new brand – Creative Cloud. And the Photoshop version included in this suite is named Photoshop CC. The CC version( Originally 14.0, and will be continuously maintained and upgraded) has 3D content as Photoshop Extended, which means the standard version is canceled.

Alongside Photoshop and Photoshop Extended, Adobe also publishes Photoshop Elements and Photoshop Lightroom, collectively called “The Adobe Photoshop Family”. In 2008, Adobe released Adobe Photoshop Express, a free web-based image editing tool to edit photos directly on blogs and social networking sites. In 2011, a version was released for the Android operating system and the iOS operating system, followed by a release of a version for Windows 8 in 2013.[8][9][10]

Adobe distributes Photoshop in Windows and Macintosh versions.

PSD File format

Photoshop files have default file extension as .PSD, which stands for “Photoshop Document.” A PSD file stores an image with support for most imaging options available in Photoshop. These include layers with masks, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. This is in contrast to many other file formats (e.g. .JPG or .GIF) that restrict content to provide streamlined, predictable functionality. A PSD file has a maximum height and width of 30,000 pixels, and a length limit of 3 Gigabytes.
Photoshop files sometimes have the file extension .PSB, which stands for “Photoshop Big” (also known as “large document format”). A PSB file extends the PSD file format, increasing the maximum height and width to 300,000 pixels and the length limit to around 4 Exabytes. The dimension limit was apparently chosen arbitrarily by Adobe, not based on computer arithmetic constraints (it is not close to a power of two, as is 30,000) but for ease of software testing. PSD and PSB formats are documented.[15]
Because of Photoshop’s popularity, PSD files are widely used and supported to some extent by most competing software. The .PSD file format can be exported to and from Adobe’s other apps like Adobe Illustrator, Adobe Premiere Pro, and After Effects, to make professional standard DVDs and provide non-linear editing and special effects services, such as backgrounds, textures, and so on, for television, film, and the web. Photoshop’s primary strength is as a pixel-based image editor, unlike vector-based image editors. Photoshop also enables vector graphics editing through its Paths, Pen tools, Shape tools, Shape Layers, Type tools, Import command, and Smart Object functions. These tools and commands are convenient to combine pixel-based and vector-based images in one Photoshop document, because it may not be necessary to use more than one program. To create very complex vector graphics with numerous shapes and colors, it may be easier to use software that was created primarily for that purpose, such as Adobe Illustrator or CorelDRAW. Photoshop’s non-destructive Smart Objects can also import complex vector shapes.[16]

Photoshop Language availabilities

Photoshop is available in more than 20 languages. These are the following:

Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, Finnish, French, German, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Romanian, Turkish and Ukrainian. Arabic and Hebrew are added as of Photoshop CS6.[17]

Photoshop Plugins

Photoshop functionality can be extended by add-on programs called Photoshop plugins (or plug-ins). Adobe creates some plugins, such as Adobe Camera Raw, but third-party companies develop most plugins, according to Adobe’s specifications. Some are free and some are commercial software. Most plugins work with only Photoshop or Photoshop-compatible hosts, but a few can also be run as standalone applications.

There are various types of plugins, such as filter, export, import, selection, color correction, and automation. The most popular plugins are the filter plugins (also known as a 8bf plugins), available under the Filter menu in Photoshop. Filter plugins can either modify the current image or create content. Below are some popular types of plugins, and some well-known companies associated with them:

Color correction plugins (Alien Skin Software,[18] Nik Software,[19] OnOne Software,[20] Topaz Labs Software,[21] The Plugin Site,[22] etc.)
Special effects plugins (Alien Skin Software, Auto FX Software,[23] AV Bros.,[24] Flaming Pear Software,[25] etc.)
3D effects plugins (Andromeda Software,[26] Strata,[27] etc.)

Adobe Camera Raw (also known as ACR and Camera Raw) is a special plugin, supplied free by Adobe, used primarily to read and process raw image files so that the resultant images can be processed by Photoshop.[28] It can also be used from within Adobe Bridge.

How to Organize Images?

How to Organize Digital Images and Photos

The issue behind organizing images

Nowadays most users have thousands of images and while organizing few hundred images may not be so difficult it is a headache to organize thousands or even hundreds of thousands photos. Luckily Visual Similarity Duplicate Image Finder (VSDIF) can help with this task. There is a free download available at the product’s web site so you can download and test the tool before placing an order. VSDIF is the best tool for finding duplicate photos.

Quick tutorial on how to organize images (for novice users)

Once you download and install the duplicate image finder all you need to do is to create a new project and add the folders to be scanned.

Duplicate Image Finder

Duplicate Image Finder

Click the New Project button to create a new project. A dialog box will pop-up automatically where you have to select the folder where the images are located. The selected folder will appear in the folders list panel on the right.  If you have photos in different locations just use the “Add Folder” (1) button to add more folders.

Some important notes for novice users:

  • Add only the folders with you own photo collectionsnot your entire drives.  If you add your entire drive all the images that are duplicates will be listed. This means that these results will include images also from applications and from the operating system. Some of those images are intentionally duplicated so deleting them may lead to malfunction in your applications or operating system.

Once the folders are added select the scan method.

Find the Exact Duplicate Images First

Before running a “Visual Compare” use the “100% Identical Files” mode. It is much faster and will list exact duplicates.This will help you to quickly get rid of the exact duplicate files and will reduce the amount of images that will be scanned using the slower “Visual Compare” method.

Find Similar Images

The default scan method is “Visual Compare” at 95%. Usually this should work best for you and we do not recommend lowering the value below 90% as it will lead to false positives. The levels below 90% can be used by advanced users for certain special types of scans.

Review Duplicate Image Results

Once the tool completes the scan it will list all similar or duplicate images and group them by similarity. Name, path, properties and similarity are listed for ever image in the duplicates grid. The groups are listed in alternating colors for better readability and the group number that the image belongs to is listed on the right.

Mark Duplicate Images for Deleting

Use the “Auto Check” panel in the bottom left corner to mark files automatically. By default it will mark files with smaller dimension and files size meaning that it will keep the images with the best quality. You can change these settings via the check-boxes and the advanced button in this section. Auto-Check will select all images in a group except ONE – the image that will be kept depends on the above settings.

Some important notes for novice users:

  • Always review the results before deleting or use the MOVE option and make a backup before deciding whether to delete the files permanently or not .

There are plenty of shortcuts in VSDIF that will make things easier while reviewing duplicates. You can use Space Bar for example in order to check/un-check an image. Take a look at the help file for complete list of shortcuts.

Delete Duplicate Images

You can delete duplicates manually or automatically. Using the “DEL” key you can delete the currently selected image.

Some important notes for novice users:

  • Use the delete functionality inside VSDIF to delete images. If you have scanned some folders and then later manually remove folders or images using Windows Explorer you will get “Not Found” message inside VSDIF for the missing items as they are no longer present at the location that was available during the scan process.

Once you have reviewed the results and marked the images that you want to remove you have several options. You can move the files to a backup folder before deciding whether to delete the permanently or not. The other option is to delete the file to Recycle Bin from where you can restore them if you have deleted something by mistake. The third options is to PERMANENTLY delete the files. You have to be 100% sure before using this option as there is no way of recovering the deleted files.

Final Words:

This is a very basic tutorial on how to get rid of duplicate photos and organize an image collection. You can find an Advanced Tutorial on How To Remove Duplicate Images here.
