How to Create Perfect Panorama Pictures

Panoramic shots break down restrictions on aspect ratio and angle of view. Panorama expert Jan Röpenack will show you what types are available and how high-quality images are created.

With a panorama, in English “panoramic view, holistic view”, a scene can be presented comprehensively and, if required, completely. If a conventional single shot is always fixed to a certain aspect ratio, e.g. 2:3 or 3:4, the stitching technique not only allows any desired aspect ratio to be achieved, but also allows image angle restrictions to be cleverly circumvented. There is practically no need to carry a bag full of lenses anymore, one starts photographing at the place where the motive starts and stops where it ends. Photographers who create panoramas in this way adapt the aspect ratio and angle of view to the motif and thus have far more creative possibilities than their colleagues who “only” take single images. In addition, the resolution of a panorama increases with each partial shot taken; in terms of quality, the panoramic photographer is thus at the highest level without having to invest in expensive camera technology.

Panoramas are usually classified according to their angle of view (360° or partial panoramas) and projection type. In the latter case, a main distinction is made between surface, cylindrical, spherical and cube projection. Also exotic projections like the representation as “Little Planet” are possible. Switching between the projection types is a pure software matter and takes place later on the computer with only a few mouse clicks. So you can create panoramas in different projections with the same partial shots and decide on the computer which one fits best.

One of the best examples of professional Panorama images of that kind can be found on on their Panorama wall displays on canvas gallery. Panorama pictures on Canvas

The beauty of their images lies in their natural grace. They do not seem too artificial like many other pictures today.

Let’s have a look how such images can be created:

Cylindrical Panorama – Ideal for large Image Angles

The most common type of projection, cylindrical projection, has the advantage that large horizontal image angles of up to 360° can also be displayed. Imagine you are standing in the middle of a cylinder and looking at its surface from the inside. If you represent a cylindrical panorama on a flat surface, for example as an expression, horizontal lines, except for the horizon, appear curved, and the further away from the horizon, the stronger they appear. This becomes clear in case of larger image angles, in the picture well recognizable by the roofs of the houses.

Area Panorama – the usual Perspective

For smaller image angles, surface projection is an alternative, as there is no deflection of lines. With this type of display, a wide-angle or super-wide-angle lens is digitally simulated on a “normal” camera. With very large image angles, however, distortion of objects at the edge of the image, the “Super wide angle effect”. This is not an image defect, but corresponds to the natural image. In the case of surface projection, only image angles smaller than 180° can be displayed, because on a flat surface only what is in front of it can be displayed, but not what is behind or next to it.

Spherical Panorama – for the whole Room

For panoramas that depict the entire room 360° x 180°, spherical or cube projections are possible. These panoramas are produced less for print and more for presentation on the Internet. Here they are usually integrated into the website with the help of Flash or HTML5 players. The viewer can thus move interactively in the panorama, seeing only a section in the surface projection he is used to.

Stitching – the Sewing Together of single Images

In the stitching technique, several pictures are taken one after the other, with the camera being rotated by a certain angle, the step size. The individual images are later stitched together with stitching software, e.g. PanoramaStudio, PTGui or Autopano, to form a complete image, the finished panorama. For this to work, the individual images should overlap by about 30%. Recommendations regarding the twisting angle depending on the focal length used can be found further back in the workshop and in the manuals of the panorama heads of all well-known manufacturers.

The right Pivot Point – why a Panorama Head is needed

If one turns somehow from the hand or with the help of a turning plate between the single shots, there is almost always a shift between the foreground and the background. If this shift takes place in the overlapping area, the software creates unsightly ghost images. On the other hand, if you pan around a certain point, the center of the entrance pupil, also called “optical center”, “no parallax point” or erroneously “nodal point”, this parallax effect can be effectively avoided and the software can create a flawless panorama without any later retouching.

A panorama head allows exactly this rotation around the center of the entrance pupil of the lens and is essential for high-quality and reproducible results. Here is an interesting panoramic head overview.

Why Panoramas sometimes succeed without a Panorama Head

In this context, it is important to note that the parallax effect only occurs if the foreground and background are displayed together in one shot. If the scenery consists only of background, e.g. distant mountain peaks, there is no parallax effect, i.e. a panorama head is not necessary. Panoramas can then also be taken with a smartphone, for example. In the living room, however, this will hardly be possible; here, near and far away objects can be found equally well. Beginners often look for the problem with such motives and unsuccessful attempts with the software.

Where is the optical Center?

The center of the entrance pupil is the virtual image of the aperture when viewed from the object side. “Virtual”, since the aperture is not seen directly, but through a lens system. The “center” is the point of intersection where the optical axis intersects with the plane of the entrance pupil. So if you close the aperture a little bit, look into the lens from the front and move it a little to and fro, you can roughly determine the entrance pupil.

Experiments are more precise with tripod, panorama head and experimental set-up in your own living room. Since almost all panorama heads have scales on movable parts, the values determined can be reproducibly adjusted on site. The “finding” of the entrance pupil depending on the lens used – in the case of zoom lenses also the focal length – is therefore ideally a one-time affair, which can be done in your own four walls after the purchase of new equipment. How to proceed when adjusting a panoramic head can be found further back in the workshop.

Security of VPN tools under criticism – what is true?

Due to headlines of data spying and alleged observation by governments and organizations, the topic of anonymous surfing is more topical than ever before.

The German Basic Data Protection Ordinance (DSVGO) has also been the subject of much discussion in recent weeks. In this context, many media are once again becoming aware of the subject of VPN. At one point they say you should use VPN to protect yourself.

Recently, however, there have been articles that claim the exact opposite: VPN is just a myth. But what is really true about it?

The topic of anonymous surfing has passed several stages in terms of public interest. A few years ago, only hackers and computer enthusiasts used VPNs. Due to numerous warnings in Germany (keyword music downloads, torrent software), ordinary computer users have also become increasingly interested in VPN. Shortly afterwards, the topic of data protection and privacy flared up. This has brought many new VPN providers to the market. A list of reputable VPN providers for your iphone can be found here: Depending on your needs a Smart DNS provider might be the better choice:

Security of VPN tools

To claim that VPN tools are not secure and would not provide sufficient protection is not correct. It is just as wrong to claim that VPNs offer 100% protection against all kinds of spying. The question is, what security can you really expect from VPN providers?

  1. A first study shows that most of these articles on the web have been written via VPNs by people who are not VPN experts, let alone have expertise in the field of information technology.
  2. These articles should be used with caution. Recommended and confident sources include magazines such as c’t (heise Verlag), or notes from the Chaos Computer Club.
  3. Both sources have so far commented positively on VPNs. One should be very sceptical about the contributions of the websites Golden Frog, Spotflux-Blog, Computer Fraud and Spideroak. Here, the so-called VPN lie and the VPN myth are reported without weighing up or looking at the topic from different angles.

Dubious VPN providers

First of all, it should be noted that there are a lot of VPN providers. Among them are dubious vendors who ride the trend and offer insufficiently mature VPN software. There are also providers who disguise themselves as VPN tools, but these are viruses and Trojans – special caution is required here: above all, one should keep one’s hands off advertised free VPN tools.

Which data do VPN providers collect?

Since VPN providers charge money for their VPN service, they store payment data of the user, such as the Paypal e-mail, credit card numbers or bank data. The VPN servers, on the other hand, are anonymous. This means that in the event of a traceability, an authority or organisation would only know that it is using VPN services. However, the data traffic, i.e. the transmitted data, cannot be traced. This ensures anonymity in the data flow.

However, we cannot confirm that allegedly the VPN providers create log files and also monitor the data traffic, at least not from the tested providers. The contributions circulating so far as a rumour could not go beyond pure speculation and assertion. So far, no case has come to light in which a user has been dismissed despite the use of VPNs. It is therefore clear that even when using torrent software and downloading illegal data (e.g. pirate copies), it is basically impossible for the authorities to trace the data and the IP of users. In many forums there are reports of warnings – but it turns out that the VPN connection failed in this case. Here too, the providers have already reacted and installed so-called kill switches – the Internet connection is interrupted if a VPN server fails (for example with NordVPN).

Tips To View Pornography In India Despite The Prohibition

Now internet pornography is finally completely forbidden in the large democracy of India. Porno-adoring Indians who are one of the most prolific buyers of the items in the world now need to do without more than 850 sites which the government has apparently prohibited. The countrys web service companies must make sure that their customers cant get these web sites, and a few currently have.

While nobody is really certain what exactly caused this latest crackdown, HuffPost India reports the Narendra Modi government seemingly went for the kill following the countrys highest court prodded it because of its tired way of the problem of porn in India.

Heres the complete record of the 857 websites which were obstructed. We’rent difficult anybodys right to view this kind of content, a government official involved with the procedure informed Quartz, seeking anonymity. We’re challenging the right of someone to reveal the articles. That discussion, obviously, is specious, particularly since the high court itself had previously shown that prohibiting pornography could be debatable.

Some one might arrive at the tribunal and say look I’m over 18 and how will you be able to stop me from seeing it inside the four walls of my chamber. This is a breach of Article 2 1 [right to individual freedom], key rights H.L. Dattu had mentioned last month.

To increase that, government resources informed Quartz which they just expect the prohibition to be completely enforceable, offered the huge amounts of adult articles on the world wide web along with the several paths for obtaining them. Essentially, the prohibition appears mostly emblematic.

Thus, if you are in India, heres a tough manual to circumnavigating the authorities latest on-line shenaniganor, why the Modi authorities tried joke on on-line pornography is completely absurd:

The 850-strange restricted sites are just the point of the massive iceberg of online pornography that online users have entry to. So, in situation your goto website has become clogged, its perhaps not especially tough to locate yet another portal site. All things considered, the world wide web is profitable with pornography (even though no one understands just how much) as well as the largest of websites once seemingly attracted as much visitors as Google and Facebook.

If youre nevertheless enthusiastic about these restricted websites, just make use of a proxy. A clutch of proxy websites including HideMyAss, Free Proxy, and inCloakshould permit you avoid an web companies web process (Internet Protocol Address) tackle and hook up to any web site.

Whenever doesnt perform, change to the handy VPN course, which our Oriental neighbors assiduously apply to break their Fantastic Firewall. Pick from many different complimentary or compensated VPNs, depending in your readiness to cover to perform.

Subsequently, theres a couple of societal networksincluding Reddit, DailyMotion and VKontaktethat host large levels of adult stuff. Actually while these web sites say that simply adults are permitted in to webpages with adult articles, it’snt required to enroll of all.

Needless to say, the planet of torrents remains unaffected. It’s, certainly, mo-Re period eating than rapidly loading articles but it gets the occupation done.
Indias substantial and pervasive greymarket of off line porn is still another alternative. A porno DVD might be purchased for only Rs30, while some vendors additionally provide to add articles on a memory stick at actually more affordable prices. Simply see your neighborhood marketplace. If everything else otherwise fails, reserve a admission to Khajuraho for motivation.

Windows or Linux

Among the most efficient ways Linux secures its systems is by way of privileges. There are a number of striking advantages for Linux. I have already been around the Linux community for at least ten years now. Take into account these items for Linux servers.

You’ll find Linux Mint platform to be highly robust, fast, flexible, enjoyable, user friendly, with a ton of software necessary for an usual user already installed and extremely stable. Fortunately, there are a number of methods to run Windows applications on Linux. We must mention, however, that lots of Linux variants will need an adjustment period for all those familiar with Windows or OSX. On Linux or Unix this may be achieved utilizing the command.

Windows or Linux Explained

The most recent Mac computers supply an important advantage in how they’re also compatible with other operating systems like the Linux, Windows XP, Windows Vista, etc.. For instance, Windows Vista Ultimate needs 15Gb simply to install, however a small Linux installation might just need half that. It sounds strange consideration to do, but VirtualBox is actually a normal OS X program which emulates a normal PC. There’s also a Linux version also.

Compatibility worries, generally, don’t affect Windows users. Mac technical support is, in addition, excellent.

  • In a Windows box, you can put access-control mechanisms with no software add-on. Frequently, this comes at an extremely low cost, and together with the choice to upgrade to dedicated server hardware and redundant online access, at a greater cost.
  • It may be run in a number of forms on practically any operating system (such as OS X and Windows).
  • Sometimes perhaps it does not be possible to have a whole Linux installation in an organization, because of company rules or even a restrictive computer administration.

Users will probably be particularly delighted at the broad choice presented by free internet mac games which have hit the market in the last few years. It seems sensible that Windows would have the absolute most software choices, which it does.

What to Expect From Linux?

Doing this enables you to make and manage your own server architecture entirely in-house. You may be able enough to get Magento to run beneath a IIS, but it’s neither supported nor recommended. Windows is actually an extremely capable server platform, particularly if you will need to run ASP or ASP.NET scripting. In Windows, utilize the mklink command to generate symbolic links.

Getting your own server is a superb approach to start, build a website within the privacy of your network, and prevent paying for hosting services when you’re not even prepared to put them all to use just yet.

Managed VPS hosting servers are truly the most useful meprocessor-1371357_960_720ans to go if you’re not very tech savvy or don’t possess the employees accessible to look after any technical concerns that can arise with the hosting. Linux hosting is possibly the most common hosting platform on earth. If it isn’t root, it will almost certainly be your cPanel username.

You’ll get skilled pros who’ll deal with any issues with your hosting server that could develop. If you’re a professional site developer, you most likely already know which hosting platform you prefer, or at least that there’s a difference between both!
