Timelapse Guide (Compact Digital Cameras – Part 2)

March 7, 2010 - 7:21 am 25 Comments

Onward we go to the compact cameras that I’ve found with a built-in interval timer (intervolometer). Please add to the list in the comments! I’m always looking for more compacts that have timers. Sorry that I lingered on the almost impossible to find Epsons but they served some other important points.

Are memory cards supposed to come with digital cameras?

February 15, 2010 - 8:09 pm 4 Comments

I just bought a used digital camera for my grandmother… I naturally assumed that all cameras come with a memory card because mine did (I have a cannon)

After talking to my mom she said that the her brand new camera didn’t come with one…

So i guess I’m trying to figure out if I was scammed or if it is common for digital cameras NOT to come with a memory card.

Thanks!

Depends upon what you buy… I bought a Canon and it came with a 32 mb memory card… basically it allowed you to take 6 pictures on the best settings (highest resolution).

You’ll have to buy your own 1 gb card or better. In the US, they are relatively inexpensive, I bought a 2 gig card for $12.

So I don’t think you were scammed… the larger memory card is extra. However, I’m surprised your g’ma didn’t give you the memory card she bought for the camera…

Do digital cameras and memory cards need to be removed from carry on luggage, and placed in a bin?

February 13, 2010 - 11:26 pm 3 Comments

It says on the TSA website "Laptop computers and video cameras with cassettes must be removed from their carrying cases and placed in one of the bins provided." Do I need to do the same with my digital camera (and memory cards) or can I just leave them in my bag?

Thanks!

don’t remove the memory card. it may get lost in the shuffle. leave the camera in the case. just place it in the bin. the xray will see what it is.

Can high end digital cameras now match dslr in image quality?

February 9, 2010 - 5:35 am 5 Comments

High end digital cameras keep getting larger sensors. Can these high end point & shoot cameras produce entry level dslr images? For example, can the Canon SX1IS match the Pentax K-X? I am only comparing the image quality, not zoom, video, ad audio features.

Actually high end P&S cameras sensors are NOT getting bigger, they are only being jammed full of more pixels

The Canon SX1 IS still only has a tiny 1/2.3 " (6.16 x 4.62 mm) sensor, but with 10 mp populating it.

The Pentax K-X on the other hand has a sensor that is over 15 times the size of the SX1 IS or 23.6 x 15.8 mm. A better way to show this is by listing the pixel density of both

SX1 IS = 35 MP/cm²
K-x = 3.3 MP/cm²

You can see, not only are there fewer pixels per cm², but for that reason, they are much larger pixels which can collect more light upon exposure and thus produce less "noise" across the board.

This should clear up your misunderstanding about pixel counts

Are there any digital cameras and/or camcorders offering optical zoom in video mode?

February 6, 2010 - 9:36 pm 1 Comment

Hi, anybody knows if there are any digital cameras and/or camcorders offering optical zoom in video mode?

All I’ve ever had are camcorders and digital cameras that feature only digital zoom when recording video, and the quality of that zooming is lousy; you see the quality difference immediately, when playing back the videos.

If anybody knows, I’d appreciate some suggestions, preferably budget cameras, USB compatible, so I can transfer to my PC.

Thanks a lot in advance for your suggestions.

Of course there are, just not many. Save for cameras with mechanical zoom rings (which obviously can’t prevent the user from using the zoom during the video recording, so they allow it), though, most cameras with small optics use zooms electronically operated (with zoom in/out buttons, tipically), and for those, it’s much rarer to find zoom-while-recording-enabled ones. The reason usually given by the manufacturer is that the motor drive that extends the zoom makes a noise that would be catched up by the microphone in the audio recording.

The most usual exceptions are cameras using “folded optics” designs (mostly ultra-compact cameras, those with tiny lenses that don’t extend outside the body when zooming), because those have somewhat quieter zoom mechanisms. Not all ultra-compact cameras allow video zooming, though: the Casio EX-V and Sony T ones do, while the Fujifilm Z series and Nikon Sxx series don’t.

Done with theory, and into practical suggestions:
- The Casio EX-V line (EX-V7 and EX-V8)
- Panasonic TZ1 and TZ5 (but not the TZ2 or TZ3 models); TZ4, I don’t know.
- Canon PowerShot S3 IS, S5 IS, TX1
- Sony H3, H5, and most (of not all) of the T series.

If you’re in a budget, I’d suggest either the Casio EX-V7 or Panasonic TZ1, or some of the more modest Sony T series.

Where can I buy refurbished digital cameras to sell on Ebay?

I see a lot of people selling refurbished digital cameras on EBay, what is their source?

I think you get them from the manufacturer.

Why are some people still using film cameras instead of digital?

Are there any particular advantages to film over digital cameras.
I understand dancingirls comment about saving gas.
With digital there is no need to go out of your way to drop off films or prints or to pick them up.
I still like film.

If I were starting out in photography today, I’d probably go digi. However, since I started about 45 years ago, I’ve got a lot of very robust, capable film equipment that does what I need it to do. Advantages of film? It doesn’t suffer from the short and long-term built-in obsolescence problems of digital equipment and storage media. Using it teaches you the basics of photography more effectively than digital. Ultimately, film image quality is higher than digital. Black & white printing is a craft I enjoy, more so than managing a computerised ‘workflow’. Actually, I’ve got some printing I need to do now………..
Dancinggirl….’saving on gas?’ You’ll have to explain that one.

How long till digital cameras come with HD video recording as the norm?

January 30, 2010 - 4:11 pm 2 Comments

Currently most digital cameras with video recording do so at VGA resolution, which is 640×480. HD resolution is 1280×720 or 1920×1080.
Uhm101, I’ll agree that while they don’t do everything well… they give you the flexibility to take both video and still images. For some people this convenience is great especially when traveling and you don’t want to carry lots of equipment around. Just look at a Canon A720 camera. It takes good photos… and gives you okay videos when you want.

Never I hope. Multifunction devices do all things in a mediocre fashion.

How do I avoid the delay in digital cameras?

January 28, 2010 - 11:03 am 5 Comments

With my digital camera, purchased in 2002 for a high price from Sony, I have about a four second delay when attempting to capture images of my children. I push the button for a great shot, but wind up with a picture of the backs of their heads as they run away. When shopping for a new digital camera that I can "point and shoot", do I need "SLR", or can other more moderately priced cameras give me the results I need? I just want to aim and shoot, dammit, but not spend $600? Anyone? Thanks for reading either way…

Yes certainly an SLR is the ultimate, but here are some tips for other cameras.

Avoid use of flash

Select manual focus if you can (focus automatically at the right distance and then switch to manual so that it doesn’t re-focus)

Use manual settings if you can. If the camera allows you to set manual aperture and shutter speed, use those settings. You still get a guide to show you the right light, but this will avoid the camera doing a fresh measurement when it actually goes to take the shot.

Here is what your camera does when you press the shutter. It decides what is close to the camera and what is furthest away. It then picks the most likely subject of your photo. It then auto focuses on that subject (usually closest object). It then checks to see whether flash is operational and if so if it’s needed. Then it decides how much flash it will use. Then it measures the light a final time. It then sets the aperture and shutter speed. Then it takes the photo.

Making as many of these decisions as you can for the camera minimizes the time it spends setting itself up before shooting.

Older (2-3 years) camera were slower at doing these calculations and adjustments than newer (< 1 year) cameras are. So a newer camera will definitely be better for your application. But if you are purchasing a new one, be sure to see what manual features it has, and then learn how to use them.

4 seconds is a very long delay, modern cameras typically have this down to 0.8 of a second, but even then it is very hard to take a photo of a child bouncing on a trampoline for example. The more money you spend (in general) the faster the camera will be.

The new Fuji S6000 (see link below) Is an advanced non slr camera that allows for a high degree of manual control. This is a somewhat bulky camera, but will take excellent shots for most people. Most major brands have models in this class of camera.

I live in Australia so unfortunately I cannot assist you with price.
