Sign in Sign in Sign in corporate. Browse Search. Ask a question. It's a traditional way to open and close a Leica since a long time ago when there was real film under the bottom plate. When you look at the bottom of the Leica M9 you see this shape that looks like the shape of a film cassette.
It's not for decoration. When you look at the brass bottom plate, you see that's the space for the lock mechanism. The little piece of chrome sticking out of the side in the bottom goes into the bottom plate so that it stays there when the bottom plate is locked. Sometimes you will see the error message "Bottom cover removed" and you have to find whether you forgot to put it on, or it's not properly mounted. The way the Leica M9 knows is that the small piece of extruded metal on the bottom plate doesn't press down the small contact next to the battery the little black one; the big white is for releasing the battery.
The camera would work perfectly fine without the bottom plate, except Leica made this contact that prevents it from working without it. Should you find yourself on a mountain top and you have lost the bottom plate, you'll have to find a way to keep this small contact depressed to keep using the camera. A piece of chewing gum or something similar will suffice. The hole you see in the bottom is to make space for the tripod mount that sits on the bottom plate to the right in this picture.
In the later Leica M the tripod mount sits on the actual camera body and there is a hole through the bottom plate instead more stability as the camera and not just the bottom plate is attached to the tripod. Note that I removed the protective plastic of the bottom plate, as well as the sticker that tell all the EC rules the camera complies with.
Prettier that way I think. The serial number of a Leica M is engraved on the hot shoe. On lenses the serial number is usually engraved in white, visible from the front, or sometimes on the side of the lens barrel.
The hot shoe, or flash shoe, is made so it corresponds with Leica and Metz flashes. It's a continuous debate if a Leica M needs a hot shoe or not as so few would use a flash with it. But at least it holds the serial number and - I guess - works as a decoration that reminds us of the old days.
By the way, it was Leica that invented the hot shoe back when it was used for mounting the first rangefinder, and later a viewfinder, to the camera.
The lenses often have a number on them. Lens shades and other accessories may also have a number. It is not a serial number but solely records which model it is.
Sometimes similar looking lenses may be different model numbers , indicating slight or major changes of the mechanical or optical design.
Paul Viio in Cannes, May Manuel Studer in Rome, May New release March Thorsten Overgaard in Berlin, May I hope you enjoyed this look back at the previous Leica M models vs the new Leica M There are plenty of pages to read here about the different cameras.
Basically means 1 divided with. But why is it on the front of the lens? The 1: itself is a ratio, that indicates that the aperture diameter 25mm is the ratio of 50mm divided with 2. It's a strange way of writing product information on modern products, but here's how it's right: a A lens is called a 50mm lens because there is 50mm from the sensor to the center of focus inside the lens.
In photography the frame within the widt of the film is 24mm on the width and 36mm on the lenght of the film roll. The camera has a smaller sensor and hence uses a wider lens to capture the same image as a "35mm camera" would. Example: A camera with a 12 x 18 mm sensor has a 14mm lens on it, and even the lens is actually a 14mm, it is specified as a 28mm lens 35mm which means that the resulting image is equivalent to a 28mm lens on a 35mm camera.
Not because of viewing angle but because of size ratio. The idea is that the camera does the focusing itself the word auto comes from Greek "self". The aperture blades inside the lens is clearly visible in this photo. Aperture Priority Mode. In most lenses, optical design concentrates the focus of blue light and green light into a single plane, but red light falls slightly into another plane of focus. Red subjects, therefore, would be ever so slightly out of focus compared to blue and green subjects in the same frame.
Not sure you'd ever notice though, the difference is so slight. This is the same basic principle that requires you to shift the focus for infrared photography, related to the wave length of red light.
In APO lenses, the design and expense has been put in to making red light focus on the same plane as blue and green. Under a microscope you would see that all light subject is now in focus, creating a sharper image overall. Leica prides itself on making most of the frame APO correct. Most lenses have a spherical design - that is, the radius of curvature is constant.
These are easy to manufacture by grinding while "spinning" the glass. This design however restricts the number of optical corrections that can be made to the design to render the most realistic image possible. These elements can be made by 1 expensive manual grinding, 2 molded plastic, or 3 Leica's patented "press" process, where the element is pressed into an a spherical "non-spherical" shape. This design allows Leica to introduce corrections into compact lens designs that weren't possible before.
Practically, the lens performs "better" up to interpretation due to increased correction of the image, in a package not significantly bigger than the spherical version. There is another Aspherical lens manufacture technique: an uneven coating layer is applied to a spherical lens.
The coating is thicker on the edges or on the center, depending. Canon "Lens Work II" calls these "simulated" aspherical lenses.
The idea is that when a camera has auto- something , it does that something by itself. It's simply noise; the result of uncontrolled algorithms working overtime with an image the sensor really can't see because it's very dark. If your image has vertical lines in it, it is more likely that the sensor needs remapping. This image at ISO, underexposed and then brought up to correct exposure in Lightroom, displays banding: Horizontal lines in the image.
Any other setting is an algorithm that figures out how the image whould look if there was 64 times more light, or half the light, etc. When you go up, the decrease is much less. For some sensors, you loose stops by going down 1 step in ISO, but can go 8 steps up and only loose 1 stop in dynamic range.
The closer you get to something, the 'more' bokeh' you get in that the focus becomes less for the background and foreground at close distances than at long distances.
Bokeh : The visual quality of the out-of-focus areas of a photographic image. Photo at Bar del Fico in Rome. When the ring by the Shutter Release on top of the camera or in the menu of digital cameras that doesn't have such a feature on the outide of the camera is moved from OFF to C, the camera takes series of images as long as the shutter release is pressed down. In some cameras the speed of continious shooting can be adjusted.
Johannes Kepler mentions Camera Obscura in They're made through a special manufacturing process that allows the conversion to take place in the chip without distortion. This creates high quality sensors that produce excellent images. But, because they require special manufacturing, they are more expensive than their newer CMOS counter parts.
In most cameras there is a shutter curtain just in front of the sensor, and in SLR Single Lens Reflex cameras there is also a mirror in front of the shutter curtain. In the Leica TL2, there is a mechanical shutter curtain from 30 sec.
This offers flexibility because each pixel is treated individually. Traditional manufacturing processes are used to make CMOS. It's the same as creating microchips. Contrast - The degree of difference between tones in a picture. The way digital zoom works traditionally is that the camera simply crops the picture; so you get closer, but without resolution. In other words, it's the same as if you took a normal photo and then cropped into the center of it.
This is a feature often offered in video recorders and sometimes for tele lens still photography so as to avoid motion blur when the lens is moving during slow shutter speeds. Lens designers can correct for distortion to a degree so the whole image field is perfect corrected and all lines remain straight.
The eye adjusts for distortion so we always see vertical and horizontal lines straight when we look at things. Even when you get new prescription glasses if you use such , you will often experience distortion in your new glasses.
After a few days they eyes have adjusted for the glasses and the distortion you saw to begin with is now gone. Also see my definition on Perspective for more on the eye and optics.
It is a single file that contains the raw image data from the sensor of the camera as well as date, time, GPS, focal length, settings, etc. A Camera Raw profile that is specific for that camera in the computer helps the software program, for example Adobe Lightroom, to translate the RAW data into the image. A raw file or DNG is simply the full recording of digital data 1's and 0's from the sensor.
In the computer, the sensor data is translated into the exact colors, via a camera profile. Depth - Distance between front and back. Distance from viewer and object. This is how much of the image will be in focus. Shallow DOF is a generally used term in photography that refer to lenses with very narrow focus tolerance which can be used to do selective focus; for artistic reasons or for specific storytelling, like making irrelevant subjects in the foreground and background blurry so only the subjects of essence are in focus and catches the viewers eye.
Depth of Field : Focus is on the flowers and the photograph on the desk and the foreground and background is blurred as the depth of field is narrow. Another rule: The closer you go to a subject the less focusing range , the more narrow the Depth of Field will be.
Depth Of Field scale from Fujifilm. Dynamic range. Historically derived from the original 50mm f3. Later that year the 50mm f3. The name is obviously derived from the earlier and slower "Elmar" designation. Professor Dr. Max Berak was employed at Leica in and was the architech of the first Leica lens which Ernst Leitz asked him to design for the "Barnack's camera" the prototype named after Oscar Barnack who invented it.
Photo by Marco Cavina. The idea is that at least one of the images will be correctly exposed. Often given in mm, for example 90mm. In the past they were often given in cm or inch, for example 9. One f-stop is a doubling or halving of the light going through the lens to the film, by adjusting the aperture riing. Adjusting the f-setting from f 1. Most Leica lenses has half f-stops to enable the photographer to adjust the light more precicely. Internal reflections between and within lens elements inside a lens.
Mostly, flare has a characteristic "space travel" look to it, making it cool. Particularly in older lenses with less or no coating of the glass surfaces to suppress this, it can be a really cool effect.
In newer lens designs, the coatings and overall design try to suppress flare and any reflections to a degree, so that there is seldom any flare to be picked up moving the lens to pick up a strong sunbeam , but instead a "milking out" or "ghosting" of a circular area of the frame; meaning simply overexposed without any flare-looking flares. Sunlight creating fairly supressed flare in the bottom right quadrant of the image of a modern lens.
Lens flare in the movie, The Graduate Lens flare in Mission Impossible Fallout Lens Flare in Star Trek JJ Abrams famously said, "I know there's too much lens flare I just love it so much. But I think admitting you're an addict is the first step towards recovery ha ha ". This may result in "banding like" horizontal stripes in an image, or simply that the light you see isn't in the picture, or it looks different.
For example, you take a photo in light, and the result you get is darker. You take another, and now it is all right. The reason is that some light blinks. Here's the difference within one second notice how the light in the room, the wall light and the sign light all flicker :.
Flickering ligh is a new challenge that photographers face, which is flicering light that looks good to the eye, but result in different results in a photo. Through cinema and photography history, the three standard high-quality light soruces have been daylight from the sun , daylight HMI Kelvin H ydrargyrum m edium-arc i odide lamps and tungsten lamps Kelvin.
When I say high-quality, it's because those are the light types that ensure high color quality see the definition of CRI - Color Rendering Index in my " Leica and Photography Definitions page " and how quality light traditionally has a score above 90 CRI.
In recent years we have seen "light that flickers" because it has a pulse, such as stage light, photo lamps, video lights and of course indoor and outdoor late night lamps using LED L ight- e mitting d iode , compact fluorescent lightbulp-shaped lamps and other low-energy lamps such as halogen.
These light also generally have lower CRI Color Rendering Index below 90, and even lamps that are stated to have 90 CRI or higher, may mis out on the important red and blue tones, which will make it impossible to get the colors right, espoecially skin tones. If a stage has one or more low-quality lights which they thend to have , these will pollute the colors of the scene to some degree.
Flickering horizontal stripes or "banding"-looking stripes may appear when you use electronic shutter, and you are photographing with one or more light sources that flickers. It's a button you can program. On the Leica M10 has a front button that can be programmed to other Fn Functions. Focus, in - Sharp and clear in appearance. In Latin the word focus meant fireplace or hearth.
The German astronomer Johannes Kepler first recorded the word in this sense in Nobody uses that measurement, except those who construct lenses! For users of lenses, focal length refers to how wide the lens sees.
The 24 x 36mm Full Frame format is so "king of photography" that it has continued to be the ideal for all cameras. Besides this, there exists Large Format cameras such as 4x5" x mm and Medium Forma t 6x6 60 x 60mm amongst other sizes in that area. The reflected light may not always be in focus, so overall it looks like a "milked out" image. A subject in focus has brightened patches in front of it that come from reflections inside the lens. Hektor - Refers to the maximum lens aperture - usually f2.
The name was apparently taken from the name of lens designer, Professor Max Berek's dog, Hektor. He also had another favorite dog, Rex, which may have inspired the lens name Summarex. Max Berek knew of this because Greek history had been required during his high school education. It's a standard that was used in film and is now used in all digital cameras also.
All other levels are computer algorithms calculating the effect as if the sensor could "see" more hence noise at higher ISO levels. For each step in ISO to , , , , etc. With modern cameras the ISO can go to , , 12, and even higher without loss of dynamic range and without digital noise. Mostly referred to as JPG as in L Apparently they were originally going to use "LECA", but another camera company already used a similar name in France, so they inserted the 'i' to prevent any confusion.
Lens - A piece of glass or similarly transparent material like water or plastic. It has a shape so that it can direct light rays.
A tube or ring attached to the front of a camera lens to prevent unwanted light from reaching the lens and sensor. In the past where lenses were not coated to prevent internal reflections inside the lens, the lens hood was often essential. These days where lenses are coated, the shade serves just as much as decoration and protection bumper as well. Lens hood or Lens shade attached to the front of the lens to prevent light rays from the side to hit the optics, which could introduce unwanted light and hence reduce contrast of the image.
These days where lenses are coated, the shade serves as decoration and protection as well. Light makes objects visible by reflecting off of them, and in photography that reflecting off of subjects is what creates textures, shapes, colors and luminance. Light in its natural form emanating from the sun also gives life to plants and living things, and makes most people happier.
So far, nobody has been able to determine exactly what light is. Read more about light in my book Finding the Magic of Light. M as in "M3", "M6", "M7" etc. The "3" in M3 was chosen because of the three bright line finders for the 50, 90 and mm lenses.
Later the numbers of the M cameras were more or less chosen to follow each other. Before the M bayonet the coupling between the camera and lens was screwmount. C M nowadays refer to the Leica M line of cameras rather than the "Messsucher". It was the latest model designation using the M and a number.
The idea was inspired from Apple who name their computers for example MacBook Pro and then it has a sub- model number designation which model it is and which would define speed of processor, etc. Leica M9. Mandler, Dr. Read more in Leica History. Walter Mandler center at the Ernst Leitz Camera factory. Megapixel or MP - Millions of pixels. See pixel further down. How many units of RGB is recorded by a given sensor by taking height x widt.
On a screen the resolution you choose determines the size of the image. Say you have a pixel wide file and your screen is set for pixels wide. Then the image will fill only the pixels fo the and the rest will be empty, If you then change the screen resolution to wide, the image would be able to fill out the whole screen. But if you grew up with inches, feet and yards, you may have had a hard time grasping what a 50mm lens was. But as lenses were designed first in Europe, the metric system with centimeters and millimeters was used to describe lenses.
The reason a 50mm lens is a 50mm lens is that there is 50mm from the focus plane the film or sensor to the center of focus inside the lens. When photography was a young subject, it was engineers who made it all, and the users were expected to understand. Posted October 17, Hello guest!
