What is DSLR?

A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The traditional alternative would be to have a viewfinder with its own lens, hence the term “single lens” for this design. By using only one lens, the viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera’s sensor. A DSLR differs from non-reflex single-lens digital cameras in that the viewfinder presents a direct optical view through the lens, rather than being captured by the camera’s image sensor and displayed by a digital screen.

DSLRs largely replaced film-based SLRs during the 2000s, and despite the rising popularity of mirrorless system cameras in the early 2010s, DSLRs remain the most common type of interchangeable lens camera in use as of 2017.

How to turn you photos into cash

Hobbies can sometimes easily be turned into a money making business. If your hobby is photography and you you’re good at it, you could make some extra cash selling your photographs online. Here’s how to do that.

Stock photography is probably one of the best ways to start selling your photographs. There are literally dozens of websites where you can upload your photos. On these sites people can then purchase your photos to use them on websites, newsletters, magazines and other media. However, the competition is fierce. Hundreds, if not thousands, of photographers do this, which means that in order for you to get your photos sold they have to be of high quality as well as cheap. This in turn means that for you to make any kind of serious money off your photos you will have to upload dozens or even hundreds of good quality photos.

So, do you think you’ve got what it takes? Start by doing some research. Check out the most widely used stock photography sites to get an idea of what’s on offer, what customers might be looking for, and also what kind of quality is needed. Remember that even the cheapest stock photography sites will turn your photos down if they’re not good enough.

A couple of things you need to keep in mind

  • Your photos should be high resolution – customers will be able to buy your photo in different sizes/resolutions depending on what they need it for. The higher resolution a customer wants, the higher the price.
  • Try to be unique – don’t submit the same kind of photos that already exists in their hundreds on the site. Unless they happen to be exceptionally good, they will most likely not get accepted. Try to see what kind of photos are missing or at least are very few in numbers.

Selling your photos online will not make you rich, but providing you’re good and you manage to sell at all you could possibly see some nice extra cash coming your way. In the meanwhile, start taking photos, lots of photos!

Here are a few sites where you can start

Instagram to Facebook for $1,000,000,000

This is what I call a major league transfer. Facebook is paying a whopping $1 billion for this little picture company. Because this is really what it is. It’s a undeniably a very popular app, which is now also coming to Android. As you all probably know, it used to be exclusive to iPhone users to alter their photos by applying different filters.

Now, the fear would of course be that Facebook decides to make Instagram a part of Facebook, but according to Facebook this won’t happen.

We believe these are different experiences that complement each other. But in order to do this well, we need to be mindful about keeping and building on Instagram’s strengths and features rather than just trying to integrate everything into Facebook.

That’s why we’re committed to building and growing Instagram independently. Millions of people around the world love the Instagram app and the brand associated with it, and our goal is to help spread this app and brand to even more people.

We think the fact that Instagram is connected to other services beyond Facebook is an important part of the experience. We plan on keeping features like the ability to post to other social networks, the ability to not share your Instagrams on Facebook if you want, and the ability to have followers and follow people separately from your friends on Facebook.

A lot has already been written about this deal, and a lot seems to focus on negative things. My question, however, is why does it have to be a negative thing that Instagram now is a part of the Facebook community? The fact is, that most Instagram users already share their altered photos on Facebook, as well as other social media websites. The ability to post your pictures on other social networks will not be removed according to Facebook, so what’s the problem?

Why not instead try to see the positive side of this, and be happy for the creators of Instagram who will now get a well deserved payoff, and those of us who have yet to discover the awesomeness of applying different filters to pictures taken with a mobile phone.

The Canon EF 50mm f/1.8 II Camera Lens – Affordable And Just The Right Weight

The Canon EF 50mm lens is compact, inexpensive and boasts of a fast f/1.8 aperture. This is a great zoom lens for photographers who are searching for a fixed focal length. The EF lens weighs just 4.6 ounces, the least heavy Canon makes, yet due to its Gauss-type optical design it gives really clear images. This brings about an image provided by the lens, which is very close to how the eyes really view the subject. It is a fantastic lens when natural depth of field is essential for the photographs or portraits. You have the capability to take pictures of subjects very closely since this zoom lens can focus at just 18 inches. The color balance provided by this zoom lens is excellent, and there’s an one-year warranty, like all other Canon lens.

The opinions by the customers have been largely rather good, where it was a lot better than expected by many, and less than expected by others. It looks like it depends on what the expectations were. Sometimes, the customer expected more after reading through the description of the lens. Other products which exaggerate what their product is able to do, are worthy of dissatisfied customers. Generally, this lens seems to meet the expectations of the purchasers. Many purchasers were dissatisfied that the housing was completely constructed of plastic materials. Because of its flimsy structure in comparison to other lenses, you must be very careful not to drop it. Everything except for the glass is bare bones, so you should be aware of that.

Because this camera lens is rather inexpensive as compared to others, it’s worth giving it a try. It may meet your lens requirements and therefore could certainly save you some money over buying a more costly lens. Unless you are an experienced photographer, you might not even know the differences, so start lower and work your way up, as you learn and become better at shooting photos. As you would expect, there is a learning curve to using this lens which will vary with your particular earlier experience.

The Canon EF 50mm f/1.8 II Camera Lens still provides top lens quality with the exception that the housing is made of lightweight plastic in lieu of something tougher. The suitability of this zoom lens varies with your particular photography abilities; it may work well for you or it may be a let-down.

Pictures for your press release

Perhaps you’ve read my “9 steps to a compelling press release” article. Here’s a follow up about what to do with the pictures you attach to your press release:

1. Good quality pictures that are easy to obtain for the reciever can increase the turnover rate of your product.

2. The pictures should have a high technical quality, i.e. be right exposed and sharp.

3. Pictures meant for print media should have a resolution of 300 dpi and be as big as you want it to be in print. This means that a picture you want to be printed on a whole A4 page should be 29.7 cm at 300 dpi. Pictures meant for digital media only need to have a resolution of 72 dpi.

4. Photos can be saved as jpg with high quality. Logotypes and other vectorized pictures (illustrations) should be saved as eps.

5. Make it easy for those who wants to use your pictures. If one can download press material from your website, make sure they’re easy to get to. You usually don’t need special logins and passwords.
