Matrix Metering with Digital
About 18 months ago, I wrote about the problems that come with matrix metering. By evaluating multiple segments of a scene and making exposure decisions for you, matrix steals a degree of control from you.

Matrix metering on Nikon camera's is called either Pattern or Evaluative on other models.
Most brands all name the second mode, Center-weighted metering or very close to it.

Matrix metering evaluates multiple segments of a scene to determine the best exposure by essentially splitting the scene into sections, evaluating either 420-segments or 1,005 segments, depending on the Nikon D-SLR in use.
I notice this is your first matrix of this session.

This toy grows on you.
Matrix metering divides the image area into a grid and compares the measurements against a library of typical compositions to select the best possible exposure.
Matrix Metering
Multi-segment metering (originally devised by Nikon for its FA SLR of 1983 under the name AMP: Automatic Multi-Pattern metering). Matrix was introduced to the world in 1988 with the Nikon F4.
Matrix Meter - Analyzes lighting in the scene to set the optimal exposure.
Megapixel - A measure of resolution of a digital camera. 1 Megapixel is 1 million pixels. This can also describe the number of sensor elements in a digital camera.
Matrix metering is used in virtually all digital cameras for the simple reason that it is the most reliable and sophisticated type of in-camera metering.
Matrix Metering system
An exposure metering system using a multi-segment sensor and computer. Available in some Nikon SLRs.
matrix
the areas of substrate surrounding a die cut label or similar product that is discardable on use; also called waste; refer to weed.
matte finish
a dull, low-gloss, or no-gloss finish.
Matrix Metering. An exposure system that breaks the scene up into a grid and evaluates each section to determine the exposure.
Megapixel. An image or image sensor with over one million pixels.
Matrix metering
Matrix metering, and derivations of it, works by splitting the frame into sections and takes each of these into account. This is more accurate than centre weighted.
MATRIX METERING- When a digital camera has to set the exposure automatically (the aperture and shutter speed) it often uses matrix metering.
Matrix Metering
A metering method which uses the entire image; however, it breaks the area down into smaller segments and uses the individual readings to calculate the best possible exposure.
Matrix (also called Pattern, Zone, Intelligent or ESP) Metering. The camera samples specific points from all over the image. Depending on the camera, anywhere from a handful to more than 50 points may be sampled.
Matrix Metering. Most digicams have a matrix metering option which uses 256 areas of the frame to calculate the best overall exposure value.

3D Matrix Metering with 10-segment SPD
Selects 3D matrix metering which uses a 10 segment sensor to calculate the best exposure for the frame. Use D or G type lenses with 3D Matrix Metering for the optimum metering.
Matrix Metering
Also known as Segmented Metering, Matrix metering takes the total image area and breaks it into sections, which are analyzed by the camera's light meter and compared to the light values of the surrounding sections.
Active-Matrix Display
A type of flat panel LCD display used in laptop and portable computers. Active matrix displays produce a superior image to passive matrix displays.
Matrix arrays, also known as Area arrays or Single Matrix are CCDs that can capture full-colour images instantaneously. Elements (pixels) are coated alternately with RGB filters. This pattern may be in stripes or a mosaic.
Matrix and evaluative metering systems are very user friendly and do a great job. But camera manufacturers have built in proof they’re not infallible. The proof lies in the exposure compensation button.

Matrix / Multi-segment Metering Mode
While the Center-Weighted metering mode uses a simple and sometimes inaccurate method of measuring the light in you photographs, the Matrix or Multi-segment metering mode takes a more detailed approach.
I use matrix metering for wide angle, and center-weighted for macro. If you are shooting with your strobes on manual, this will have no effect.

Why not use matrix-metering with some automatic mode and let the camera figure it out? The theory seems good, but in practice it isn't very reliable. I can attest that I went this route when I first started, and results were mixed.
Evaluative or Matrix Light Metering
Typically, you'll only find this metering mode on DSLR cameras that include a number of metering choices. Evaluative metering is the most sophisticated technology.

Note that most output devices, including dot-matrix printers, laser printers, and display monitors, are raster devices (plotters are the notable exception).
Averaging, center weighted and "matrix" type metering systems will take a bit of experimenting to figure out just what the meter is "seeing".
Every digital image is a bitmap (BMP) or matrix of adjacent pixels. If you would enlarge a small area of a bit-mapped image you would clearly be able to see the pixels it is made up of.
It was generally referred to as “matrix balanced fill flash'. The nice thing about this system was that photographers could hook up multiple flash units which would slave themselves to the master flash.

This may be called Matrix, Evaluative or Intelligent metering, or something to that effect. Other options include center-weighted and spot metering.
What is the difference between using photo matrix to build this image, as opposed to just opening the multiple exposures (-2 -1 0 1 2) in Photoshop and using layer masks to blend the exposure levels together?
If your camera has different metering options such as; centre weighted, matrix, honeycomb, multi pattern or segmented any of them will suffice for the time being, however, do not use 'spot'.
Multi-segment metering, also called evaluative, matrix or honeycomb metering, is an advanced TTL (through-the-lens) metering system that interprets simultaneous readings from multiple areas in the frame to determine the correct exposure.

Actually that in Auto, P,S and A modes when 3-D matrix metering is used, the camera will override flash compensation settings and do what it thinks is best.
Exposure meter: Built-in digital camera meter that measures the amount of light when framing a photo and determines the best exposure. Matrix (Evaluative), Spot and Center-weighted are the main metering types; some digital cameras have all three.
