Scanning photos and slides

Negatives and slides can be returned to a lab and have prints made ​​from them but cropping of negatives and slides is very difficult, even impossible without a professional lab. This includes color photos as prints of the films made ​​in black and white classic thang enlarger can crop and edit. Not as easily as pictures in digital form but without major problems. There is also a problem of old photos (prints), which have been scratched, or other damage. Traditional retouching (ie, brush and pencil) of such images and doing znich copy a job for professionals with adequate equipment and with no artistic talent. Today, this technique probably is not used.

A universal solution to these problems is to scan film or photographs preźrocza, or processing it into a digital file. A picture or a negative in digital form we can freely manipulate, improve, or modify a program for processing image files. For a digital file storzenia need is a scanner and the problem is that the market there are hundreds of models of different companies and have to choose among them one that will be most useful for our needs and the needs are essentially two.

Development of print, or opaque material and for this purpose, we can buy a scanner only to opaque materials. Such scanners are relatively cheap but does not allow you to scan film and slides.

Development of films, or transparent materials, and for this purpose are scanners especially for movies only. Such scanners are much more expensive than those from the point first and they can not scan photos or document opaque.
For the amateur, the best solution is to buy a universal scanner that
in principle, is designed for scanning opaque materials, but is a snap to place video or slides and scan mode transparent materials.

Imitation or inspiration?

Often photographers get the order to portray a person in such a way as to resemble the form of film. Countless women (and many men) world recovered in the role Marilyn Monroe's dress billowing from the Straw widower and Audrey Hepburn from Breakfast at Tiffany's. Even relatively well-known people like Lindsay Lohan and Paris Hilton repeatedly posed for such photos. Pattern is not uncommon for pastiche is photography itself. Perhaps the best example is the work of Charles Ebbets in 1932 under the title Men on Beam at Rockefeller Center, also known as Lunch on the roof of a skyscraper. Theme of the pictures of the workers sitting high on a skeleton wysokościowca was repeatedly used. We had a version of the children, with actors from the show Friends. There were also brand advertising from the automotive industry - with an empty bar and suggesting that everyone just enjoy the discount on the car.

Pastiche in photography

Pastiche is by definition a work of imitation, counterfeiting features nienoszącym however, created more for praise than criticism - so different in this respect the caricature. As a humorous pastiche is colored, the boundaries between it and parody can be very smooth. This form is often used in comedies. Scenes or characters from famous films appear to the delight of the audience. Some images, like Scary Movie, almost entirely based on a bunch of parody quotes. Advertising, which often refers to stereotypes, is another area known posiłkującą the themes, or even specific songs, pictures and characters.

Humor in photography

Photography surrounds us almost everywhere - in newspapers, on billboards, Internet. We live in a world of images. Some of us stop for a moment, the other will pass without a trace of emotion. One of my favorite photos are ones that can me laugh, make my thoughts broke away from the prose of life. And I'm not talking about stupid shots mines, but of those, which pierces the photographer's sense of humor. The authors of these images can in an intelligent way to refer to famous works, themes or play with the conventions and associations. Photographer lets the viewer's eye, showing him a familiar character or situation, but not literally the same - it does not create a copy. Highlights some distinctive features, some rewrites, but that all were easily recognizable. This requires a rich imagination and a lot of skills, often feel and taste. Such work often can be an art in itself.

From a hardware point of view, perfectly fits a comparison of two types of viewfinder: a mirror and lunetkowego. Looking through the viewfinder SLR, the picture we see isolated from reality - as it were immediately placed in a black frame. Already at the entrance looks like a ready photo, a much more attractive than the real world, including because we look through the lens, which adds its own perspective. The riflescope camera's viewfinder shows you almost unchanged dalmierzowego world (only slightly scaled down, though, and since there are exceptions). What will be captured, marked in the viewfinder is a delicate frame of less than the whole viewfinder. Thanks also shows some of what is outside the frame - you can see, for example, a figure that in a moment we enter the frame and either break the scene, or to fulfill them. In addition, because we do not look through the lens, nothing interferes with perspective. Photographer has a greater bond with the reality that a photographer, because it looks at "the pictures"as in the SLR, but taking place before his eyes the scene.

The color in photography

Appropriately selected color tone photographs can perfectly the mood the scene, while not having anything to do with the actual colors. Anyway, really for us there is no such thing as "true color" because all the visual information reaching the end of the brain and are processed by him, the human perception of color has nothing to do with the wavelength, which is the actual color of the reflected light. We know that snow is white, so that we see it - regardless of whether we look at it in full sun or at night under streetlights. We are equipped with the most perfect and fastest automatic white balance system. At a time when fotografowało solely on light-sensitive membrane, the possibility of manipulating color images were quite small - you could choose a film to daylight, incandescent or fluorescent (the latter two were expensive and difficult to get.) Then the differences between the color images obtained were quite substantial. If we wanted to subtle changes (and we did not do color prints in his own darkroom), you can choose different types of emulsions were specific products (both in terms of slides and negatives.) But that's nothing compared with the possibilities offered by the figure. Even the simplest cameras today allows the user to choose from multiple settings (Daylight, Incandescent, several types of fluorescent light, shadow, etc.), in the case of advanced models (some CDs and all SLR cameras), the choice is even bigger and even gives you a stunning selection of color temperature accuracy in Kelvin with high accuracy. Customers photographers in RAW mode may choose after the shooting, while working on the computer.

The flatness of the world in photography

Aside from all aspects of the metaphysical, the world has for us the three dimensions: height, width and depth. Meanwhile photography is flat - the image has only height and width. How does it compare to the "faithful" representation of reality? How is that looking at a flat picture, we see three-dimensional world? Of course, no one doubts that looks at the photograph, for example, and not through the window, but very easy for us to find a flat image on the known dependence of the real world. As always, for any type of fraud that corresponds to the human brain. He combines and processes the image respectively of the two eyes, allowing you eg to easily assess the distance that separates us from some object - nota bene acting on the basis of rangefinders, like the camera dalmierzowym. Besides the ability to convert two-dimensional image in three-dimensional feel is useful not only when viewing photos, but even when looking in the mirror.

Is photography most faithful of all arts?

Almost always, common understanding of the photographs associated with the belief that it is a faithful reflection of reality. In the end not enough that the world looks in the pictures much more realistic than the images, it's still photographs were the result of chemical and physical processes, or simply had to tell the truth. The past decade has drastically changed our perception of photography - image editing software, allowing almost unlimited interference with the appearance of pictures and niezostawiające behind almost no trace, meant that we have become distrustful. However, thethe question of of truth in photography is still a key issue for the way in which we receive or create this art.

Converting RAW files for HDR

Important thing we can not allow any software used to do the RAW conversion on any uncontrolled interference in our file conversion parameters. In the case of Photoshop, this means avoiding the "auto" in the fields: Exposure, Shadows, Brightness and Contrast, and to prevent the white balance settings, "Auto " and "As Shot" white balance if it was set to "Auto" for shooting.

How many exporures for HDR?

Amount of radiation needed obviously depends on the scene, but before that in many cases insufficient 3 exposure in increments of 1.66 or 2 EV Minor strokes do not recommend, it makes no sense to play in an EV. In theory, would make a measurement point in the brightest and darkest parts of the scene, the quantity needed to calculate radiation, etc. In practice, the usual (using, D-SLR) doing an irradiation, roughly in line with the measurement matrix, and then check the histogram if it points to the clear shift towards overexposure / underexposure change parameters and perform another trial. If it is correct as far as erasing pictures, run bracketing, attach the hose and doing a series. If possible, you may want to change the way the camera's way of making a series of bracketingowych so as to begin from underexposure, and the middle performed exposures, and ended with an X-ray (-, 0, +). The Canon's default is different (0;-;+) and then hinders orientation. The pictures of a strong light source in the scene usually requires more of the radiation, I am often in such cases, the fifth.

Shooting for HDR

The basic condition for obtaining an image in HDR technology is to have several versions of an image of the same scene made with different irradiation parameters (possibly several TIFF files, or JPG also obtained from the various call one RAW file.) The best solution is to implement a number of irradiations of the same scene camera mounted on a tripod. Mounting must be as stable, so that the images did not differ from each other the frame, even minimally.
The individual exposure should be made as soon as possible because of the changing landscape elements during such as clouds, waves, moving in the wind, branches or podrygująca boat on the waves. Forgive me, I had to mention it even though it probably did this kind of situation does not meet. Know that I am "łódkofilem" And nothing will change.

Bracketing, an option available on most SLRs involving the execution of a series of shots of the same scene at a fixed aperture and the changing times, with the specified increments. This stroke and the number of shots depends on the type of camera, for example, in Canon EOS 5D is 3 frames with a maximum 2 EV increments, the Nikon D200 to 9 shots with maximum increments of 1 EV. This feature originally had another use but has proved very helpful in the performance of individual radiation needed to complete the picture in the HDR.

Dynamic Range Increase

Dynamic Range Increase (DRI), increase the tonal range, the method consisting in the appropriate application to each other and contain several layers of masking the same scene exposed in different ways. The most important difference, in a simplification, of course, is that DRI is a lot in practice, replacing one image with different stretches, these parts are relatively large, sometimes it can be an inch piece of heaven, while the HDR changes are occurring in each pixel image.

High Dynamic Rang

High Dynamic Range (HDR) - method of obtaining images of a much wider tonal range than recorded by the camera in a single frame consists of creating a file, usually about 32-bit color depth, formed by the combination of several images of the same scene in different ways irradiated So that the individual frames correctly register all ranges, from light to shadow. Creating such a file requires several input files, their number depends on the tonal range of the recorded scene, from my experience that 90% of cases, sufficient 3 files recorded in increments of about 2 EV, in practice, we highlight three of the same time changing the aperture relations x0.25, x1, x4.

Dynamic Range

Dynamic Range (DR), Tonal Range, the ratio of the image brightness of the party's brightest to the darkest, he is limited on the one hand by the possibility of recording equipment (eg digital camera sensor) and secondly by the possibility of an image display device (monitor, printer). This ratio for the average matrix is 500:1 (~ 8 EV), for the printer 250:1 (~ 7 EV), and a monitor 500:1 (~ 8 EV) The approximate course, have to illustrate the concept. The values found in the real world date back to 100 000:1 (~ 17 EV) and our eye sees 10 000:1 (~ 14 EV).

How much can one earn from microstcok photography?

So we start from scratch. Assume that at the beginning we can add 20 images per month. So we have 20 pictures published and accepted in our protfolio. Everything now depends on how they like the community, photos, and more specifically the buyer.

Defines a very simple parameter, namely the number of downloads pictures in a month. (Abbreviated to DL`s / M - Downloads Per Month) This ratio determines the success or the flap of our newly added photographs. I think that for someone who starts his adventure with photography photos score above 10 DL`s / M is a success.

Okay, but how does it compare to earnings? From my current experience has shown that averaging a sold image translates into a 0.8 earned $. So, sold 100 photographs give us $ 80. On is a lot of pictures which DL`s / M exceeds the value 100

Lenses from Nikon

Recently I've been researching Nikon lenses. I'm a Canon user, but some of my friends always try to persuade me to check out Nikon. I don't think I will, but must admit they do have some good stuff. I mean once you're chosen your brand it's rather hard to change (not that I really want to!). But say I did want to chnage to Nikon, I'd have to sell all of my Canon gear and buy everything from a scratch. That's why it's so important for those companies to attract beginner photographers and automatically make them loyal customers.

Pinhole Camera Basics

Camera obscura, also known as pinhole camera, is nothing more than a cubic box with a hole on one side and the other screens available. The walls are painted from the inside in black. This reduces reflections. In this box, on the one hand, it is a small hole through which light enters. On the opposite side is a dull fast, which shows scaled down and inverted image.

Pinhole Camera in Wedding Photography

The pinhole photography technique has has some interesting features, which can be used in wedding photography.

1. Focus from zero to infinity, eg wedding photos, the photographer can be in the foreground sharp, huge rings and many more equally sharp.

2. Spy character: the camera can be made of boxes of matches, beer cans, or almost anything and placed anywhere.

3. Very wide angle and lack of distortion, as in the fish eye.

4. Long time exposure pictures of wedding photography can be used as an advantage. For example in a busy and crowded urban landscape. With only the newlyweds and the buildings not moving.

5. Sooft images perfect for wedding photography.

6. Fashionable and abused in wedding photography image vignetting comes free with a pinhole camera.

Here are another posts of mine about pinhole photography and on how turn a room into a camera obscura.
