A white paper is a report or guide that informs readers concisely about a complex issue and presents the issuing body’s philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision. A white paper is the first document researchers should read to better understand a core concept or idea.

The term originated in the 1920s to mean a type of position paper or industry report published by some department of the UK government.

Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper is closer to a marketing presentation, a form of content meant to persuade customers and partners and promote a certain product or viewpoint. That makes B2B white papers a type of grey literature.

The term white paper originated with the British government and many point to the Churchill White Paper of 1922 as the earliest well-known example under this name. Gertrude Bell, the British explorer and diplomat, was possibly the first woman to write a white paper. Her 149-page report was entitled “Review of the Civil Administration of Mesopotamia” and was presented to Parliament in 1920. In the British government, a white paper is usually the less extensive version of the so-called blue book, both terms being derived from the colour of the document’s cover.

White papers are a “tool of participatory democracy … not [an] unalterable policy commitment”. “White papers have tried to perform the dual role of presenting firm government policies while at the same time inviting opinions upon them.

In Canada, a white paper is “a policy document, approved by Cabinet, tabled in the House of Commons and made available to the general public”. The “provision of policy information through the use of white and green papers can help to create an awareness of policy issues among parliamentarians and the public and to encourage an exchange of information and analysis. They can also serve as educational techniques.”

White papers are a way the government can present policy preferences before it introduces legislation. Publishing a white paper tests public opinion on controversial policy issues and helps the government gauge its probable impact.

By contrast, green papers, which are issued much more frequently, are more open-ended. Also known as consultation documents, green papers may merely propose a strategy to implement in the details of other legislation, or they may set out proposals on which the government wishes to obtain public views and opinion.

Examples of governmental white papers include, in Australia, the White Paper on Full Employment and, in the United Kingdom, the White Paper of 1939 and the 1966 Defence White Paper.

Since the early 1990s, the terms “white paper” or “whitepaper” have been applied to documents used as marketing or sales tools in business. These white papers are long-form content designed to promote the products or services from a specific company. As a marketing tool, these papers use selected facts and logical arguments to build a case favorable to the company sponsoring the document.

B2B (business-to-business) white papers are often used to generate sales leads, establish thought leadership, make a business case, grow email lists, grow audiences, increase sales, or inform and persuade readers. The audiences for a B2B white paper can include prospective customers, channel partners, journalists, analysts, investors, or any other stakeholders.

White papers are considered to be a form of content marketing or inbound marketing; in other words, sponsored content available on the web with or without registration, intended to raise the visibility of the sponsor in search engine results and build web traffic. Many B2B white papers argue that one particular technology, product, ideology, or methodology is superior to all others for solving a specific business problem. They may also present research findings, list a set of questions or tips about a certain business issue, or highlight a particular product or service from a vendor.

Layers are used in digital image editing to separate different elements of an image. A layer can be compared to a transparency on which imaging effects or images are applied and placed over or under an image. Today they are an integral feature of image editor.

Layers were first commercially available in Fauve Matisse (later Macromedia xRes), and then available in Adobe Photoshop 3.0, in 1994, but today a wide range of other programs, such as Photo-Paint, Paint Shop Pro, GIMP, Paint.NET, StylePix, and even batch processing tools also include this feature. In vector image editors that support animation, layers are used to further enable manipulation along a common timeline for the animation; in SVG images, the equivalent to layers are “groups”.

There are different kinds of layers, and not all of them exist in all programs. They represent a part of a picture, either as pixels or as modification instructions. They are stacked on top of each other, and depending on the order, determine the appearance of the final picture.

In graphics software, layers are the different levels at which one can place an object or image file. In the program, layers can be stacked, merged, or defined when creating a digital image. Layers can be partially obscured allowing portions of images within a layer to be hidden or shown in a translucent manner within another image. Layers can also be used to combine two or more images into a single digital image. For the purpose of editing, working with layers allows for applying changes to just one specific layer.

The standard layer available to most programs consists of a rectangular, semitransparent picture which may be superimposed over other layers. Some programs require that layers cover the same area as the final canvas, but others offer layers of multiple sizes.

A layer mask is linked to a layer and hides part of the layer from the picture. What is painted black on the layer mask will not be visible in the final picture. What is grey will be more or less transparent depending on the shade of grey. As the layer mask can be both edited and moved around independently of both the background layer and the layer it applies to, it gives the user the ability to test a lot of different combinations of overlay.

An adjustment layer typically applies a common effect like brightness or saturation to other layers. However, as the effect is stored in a separate layer, it is easy to try it out and switch between different alternatives, without changing the original layer. In addition, an adjustment layer can easily be edited, just like a layer mask, so an effect can be applied to just part of the image.
