1~2 and 3. On CCDs, the amplifier is effectively in the corner of the sensor, but on CMOS, there is an amplifier built into each photosite, dispersed throughout the sensor. See here. As mentioned in one thing I recently discovered, most DSLRs have an amplifier before the ADC (Analog-to-Digital Conversion). They tend to max at 800 or 1600 ISO and are all ...

I'd say it's worth it. My friend Nick has written a fairly decent overview of the zone system which uses an example that was taken in colour on his digital SLR.

Given your situation, I would lean towards Canon, simply because that's what most of your friends have. There are a few benefits in having similar equipment: You could share lenses (try before you buy) More specific advice, because different brands have different names for the same things (IS vs VR), so you'll be able to pick up the names quicker.

The technology is not primtive but actually quite advanced. Every component important to photography is constantly being researched and improved. The cost of those improvements are passed on to buyers, just as with everything else. Furthermore some of what you suggest would render a camera worse for photography: The interface of each manufacturer is ...

In addition to all the other suggestions, the user interface and the general "feel" of the brands are very different. Since your friends have several brands, try them all out. One brand will usually just feel better to you than the others. It's very subjective. Maybe the grip on one is more comfortable, or maybe the button layout fits your hand better. I ...

I'm totally with Itai on this one. DSLR's are by no means "primitive". On the contrary, they are very advanced and refined tools for serious photographers. To answer each of your points directly. A primitive interface If you are referring to the menu systems...they may visually look primitive, however they are designed for functionality, not looks. ...

If you are shooting by looking at the rear LCD or an Electronic Viewfinder (EVF) to frame your shot here is the most likely scenario without more information from you added to the question (Camera model, specific settings, etc.). The LCD screen (either on the back or inside the EVF) is using the sensor to produce a series of pictures much like a video ...

Leaving aside the image quality for the moment, you have some fundamental differences between the listed lenses: Canon 50mm f/2.5 - it's a native Canon lens, so you get autofocus and full exposure modes. You can get it new with warranty, and it's not expensive. Voigtländer 40mm f/2 - it has an EF mount but no autofocus. You'll get exposure automation, ...

Yes. The ISO setting is the sensitivity of the sensor -- in practice the amount of amplification applied to the signal from the pixel on the sensor to get a real result. In theory, you could post process to produce a similar result to that of a lower or higher ISO using exposure compensation - I've always found I've got much better results shooting it right ...

Yes, ISO setting does affect the image data stored in the RAW file. Here are two images, shot at the same time/place (almost - this was shot hand-held, without much attention to composition), with the same aperture (f/2.8) and shutter speed (1/100). This first image was shot at ISO 100 and adjusted +2 stops in ACR to an effective ISO of ~400. All ...

There are a lot of good common sense replies to your query already, however I haven't seen (maybe I missed it) probably one of the most important reasons to pick any brand - the lenses and your use for them. You need to consider what you are going to be shooting & what your budget is and maybe let us know. If you are a sports shooter then you need fast ...

DSLRs are a subset of SLRs. In other words all DSLRs are also SLRs, but not all SLRs are DSLRs. SLR is an abbreviation for Single Lens Reflex. What this means is that composition of the scene, focusing, and actually recording the image are all done trough the same lens. The word reflex relates to the way a mirror is used to view the scene and focus it ...

Why do high resolution cameras shoot stills at high resolutions, but only typically shoot video at 1080p which is about 2 megapixels? For example I have a Sony-NEX 6 which can shoot stills at 16 megapixels but only 1080p by 1920p video. There are several reasons why most high resolution still cameras that also shoot video don't produce video at ...

You are right that thinking about the brand is important among DSLRs. The reason is all about the lenses, each brand gives you access to a different lineup so what you must absolutely do is check what current lenses exist in each brand. To see all the current lenses in one place go to Neocamera's Lens List and click on each brand that interests you one at a ...

Canon and Nikon are both so similar these days, it really doesn't matter much which brand you chose. Each has slight advantages over the other, but it really doesn't matter much. In general, take a look at what your friends have, and get the same kind. Canon therefor would be your pick. As to what equipment to buy, make sure you get a 50mm/1.8 lens, aside ...

While there are a lot of ways to approach this question, the two things that stand out to me, in this modern and competitive market (where many of the brands are very similar in many ways, especially "quality", however one chooses to define that), are these: Ergonomics. Different brands have different controls -- from the positioning and type of buttons ...

The wikipedia article on this has some good information. Basically, yes, it is probably still worth the time to learn the system, but you probably won't use it in it's original form. The Zone system will tell you what the exposure and dynamic range should be, and the histogram will tell you what the exposure and dynamic range is. The benefit is in knowing ...

If you're looking for a free program to let you shoot tethered with your Nikon, this post discusses a few of the options.

I've purchased equipment from following site with great satisfaction: bhphoto.com adorama.com keh.com

That depends entierly on what you mean by the question. If you mean the point where there is about the same amount of detail recorded, perhaps 5 MP, 8 bpp. If you mean the point where you can make an enlargement the same size without feeling that the quality is lacking, perhaps 20 MP, 12 bpp. If you mean the resolution that you can scan a negative and get ...

What is your definition of better? I used to love being in the darkroom. It's a unique experience and very creative. It's wet, smelly, dark, solitary and mind expanding. While I have all the equipment, I haven't used it in decades, the digital stuff reaches the same goals and close to the same results. But it's not the same. I don't believe that there are ...

You can darken the pupils in a separate layer and tweak the transparency. You'd want to tweak a bit more on the edges of your drawn part to make it less fake. If you have a photo with the natural color, colorpick that and draw with that color instead of black. This tutorial just uses black, but shows the general procedure: ...

Does it matter to you to do your own development? It is probably easier just to have a good print house do the photographic print for you. Any good professional print shop is going to be using a laser or LED photographic printer where they are using a photographic developer. The only difference is that instead of using a negative, they use a laser or LED ...

Nowadays, both terms are using interchangeably because the vast majority of SLRs in production are digital and there was not been a new model of another type of SLR in years. SLR refers to a camera with a Single Lens and a Reflex mirror to bend the light path to the optical viewfinder for framing. A DSLR is a Digital SLR, meaning it has a digital sensor to ...

You own the copyright. What you most likely want to do is retain the copyright, but assign rights to the clients to use those images. Unless you expressly sign over copyright to them, you will retain the copyright. You can't resize an image into a JPG and give them copyright on that file. The copyright gives the copyright holder (you) the right to make ...

It most definitely is a image sensor/CCD/CMOS issue. These tend to fail over time due to heat, which could explain why it worked the first couple of months. It also isn't exposing properly (due to faulty CCD) hence the swirls and exposure of half a second. There was a time where they recalled their image sensors/CCDs but it was a while ago. It might be ...

Super 8 is a pretty tiny format: 4.0mm x 5.8mm. At first glance, this would appear to be even smaller than most of today's compact cameras, which have 1/2.5" (10mm), 1/1.7" (15mm), etc. sensors. However, due to a weird anomaly in how CCD sizes are specified, that's actually just larger than a 1/3" CCD, which is pretty common. Many webcams, security ...

I'm pretty sure they don't sell a digital super-8 back after some Googling around. I'm also pretty sure the required level of expertise to make such a thing is quite high. I'm not going to say its impossible, but well beyond the hope of the average person hoping to save some money on digital recording. If you're interested in shooting the film and ...

You can't at the moment, and I would suspect that you'll never be able to either. It was proposed a few years ago but never got off the ground. The idea was to have a flexible ccd sensor that would go across the back of the camera instead of the film and the electronics would be in the "cannister". More information and links It resurfaced as an April ...

What are the Most Important Attributes? 1. The Tripod The most important factor will certainly be the tripod. Telephoto shots taken with a great lens handheld will be inferior to shots taken with a mediocre lens on a middling-to-good tripod. 2. Autofocus Good autofocus is almost indispensable if your subjects are moving (I'm going to assume they might ...
