Dupa recordul panoramelor de 26 gigapixeli de anul trecut (Paris si Dresda) si de 18 gigapixeli (Praga), 360cities ne incanta acum cu alte cateva bunatati:

Londra – 80 gigapixeli

Dubai 45 gigapixels

Dubai e prezent in lista celor mai bine definite locatii panoramice cu o fotografie facuta de gigapan.org (via http://www.gadling.com).

gigapan: Dubai 45 gigapixels

Detalii tehnice:

4,250 individual shots taken with a Canon 7D and the 100-400mm f/4.5-5.6 L zoom at 400mm. Total shooting time circa 3 hours 30 minutes, in 37C heat (that's the temperature in the shade - the camera and lens were almost too hot to touch at the end of this).
PC - i7-920, 12GB RAM, 2x 300GB Velociraptors (not RAID). On attempting to stitch this the first time, I was told I needed just over a terabyte of scratch space, so I had to go out and buy a 2TB disk and install that as well!
Power and storage:
All 4,250 images (.jpg only) managed to fit on a single 32GB CF card, taking up 27.5 GB.
HUGE thanks to South Korean property developer Bando Construction and Engineering for making available the location to shoot this from - Ubora Towers in Business Bay, Dubai.
*edited the date taken field as it was showing the date the stitching was completed, and not the date the photos were taken.*

SDXC microSDXC

SD memory cards come in a variety of speed classes and three different physical sizes: SD, miniSD, and microSD. The SD card is typically used in personal computers, video cameras, digital cameras and other large consumer electronics devices. The microSD and miniSD cards are commonly used in smaller electronic devices like mobile phones. Some manufacturers offer adapters to fit a traditional SD card slot, allowing even greater versatility and flexibility to use the card in a mobile phone as well as a computer or video camera.

To determine the right card for your device, always consult the device’s user manual or contact the manufacturer. All SD memory card formats are readily available in the marketplace and can be found in a range of retail outlets including drug stores, electronics and computer shops and Internet sites.

Choosing the Best Card – What Memory Capacity do I Need?

SD memory cards come in a variety of memory capacities designed to fit your needs and budget. The next-generation SD memory card specification, SDXC, offers the greatest memory capacity and UHS SDHC and SDXC products offer the fastest performance. Your device’s users manual may help you select the memory that is right for your device. You can also determine the best memory capacity based on how you plan to use the card. For cameras, consider the picture resolution of every photo, and for your MP3 player, the bit-rate required for smooth playback. Take a look at our reference chart that illustrates the various storage capacities.

How to Pick the Best Speed

For greatest performance, users should pair their devices with the corresponding SD memory card. Your device user’s manual will help you select the SD memory card performance that will maximize your device performance.


SD Speed Class/UHS Speed Class

Greater Performance Choices

There are two kinds of Speed Class, “Speed Class” and “UHS Speed Class.”

As a characteristic of flash memory, actual transfer speed varies. Variable speeds are difficult to reliably record streaming content such as video because it requires a constant writing speed. Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance so that minimum and constant speed is guaranteed for camcorders, video recorders and other devices with video recording capabilities under the conditional write operation specified in the specification.

Speed Class, designated as Class 2, 4, 6 and 10, is designed for normal and high speed bus interface (mode) and UHS Speed Class 1 is designed for UHS-I bus interface*. (Speed Class and the UHS Speed Class are not compatible.)

*UHS (Ultra High Speed), the fastest performance category available today, defines bus-interface speeds up to 104 Megabytes per second for greater device performance in SDXC and SDHC host products.

Marks Operable Under… Applications SD Memory Card
Speed Class 2 Normal Bus I/F SD video recording SD, miniSD, microSD
SDHC, miniSDHC, microSDHC
SDXC, microSDXC
4 6 HD ~ Full HD video recording
10 High Speed Bus I/F Full HD video recording
HD still consecutive recording
UHS Speed Class 1 UHS-I Bus I/F Full higher potential of recording real-time broadcasts and capturing large-size HD videos SDHC UHS-I and SDXC UHS-I

Fragmentation and Speed

The memory of a card is divided into minimum memory units. The host writes data onto memory units where no data is already stored. As available memory becomes divided into smaller units through normal use, this leads to an increase in non-linear, or fragmented storage. The amount of fragmentation can reduce write speeds, so higher SD card speeds help compensate for fragmentation.

The SD Association has specified operating conditions for SDHC, SDXC, SDHC UHS-I and SDXC UHS-I memory cards to guarantee the minimum speed according to the card’s speed class. Speed logos are provided to help identify cards that comply with these specifications.

The Bible According To Google Earth.

Scenes from the Bible have been imagined by countless artists over the centuries, but never quite like this. God’s Eye View portrays four key Biblical events as if captured by Google Earth. Above, The Crucifixion.

(Original article)

I know a lot of people who don’t know which is the best or the optimum resolution for their monitors (display). Therefore, I made a chart with the most popular sizes (inch) for the FullScreen (4:3, 5:4) monitors and the Wide (16:9, 16:10) monitors. The oldest, but not the forgotten monitor model is the FullScreen. In the opinion of the monitors producer, for each size there’s an optimum resolution.

So, this is what it looks like:

  • 15 inch (38cm) -> 1024×768
  • 17 inch (43cm) -> 1280×1024 SXGA
  • 19 inch (48cm) -> 1280×1024
  • 20 inch (51cm) -> 1600×1200
  • 21 inch (53cm) -> 1600×1200

For Wide Screens the resolution formats are:

  • 17 inch (43cm) -> 1440×900 WXGA
  • 19 inch (48cm) -> 1440×900
  • 20,1 inch (50cm) -> 1680×1050
  • 21 inch (53cm) -> 1680×1050
  • 22 inch (56cm) -> 1680×1050
  • 24 inch (61cm) -> 1920×1200
  • 26 inch (66cm) -> 1920×1200
  • 28 inch (71cm) -> 1920×1200
  • 30 inch (76cm) -> 2560×1600

Three issues that need to be kept in mind every time we set our resolution are:

  • the distance between the monitor screen and us
  • the refresh rate that the monitor can support in terms of hardware
  • depends on how well we see

PS: Don’t forget to relax your eyes at regular intervals of time. If you can, look out the window or at objects that are far away from you.

Nikon L20 - front view

Nikon L20 - vedere frontala

Nikon L20 - back view
Pro:
  • Compact, usor, rapid;
  • Fotografii de foarte buna calitate;
  • Bateriile alkaline (primite la cumparare) m-au tinut surprinzator de mult;
  • Cardul de date Lexar 2GB, husa, acumulatorii Nikon 2300mAh si incarcatorul asociat sunt foarte apreciate;
Contra:
  • Putin mai greoi in utilizare atunci cand vrei sa schimbi setarile fata de alte aparate/marci;
  • Poze mai “nereusite” la lumina slaba;
  • Atentie la prindere, pentru ca are tendinta de a  “aluneca” din mana destul de usor
  • Lipsa unui view-finder – ecranul lcd consuma mult mai rapid bateriile/acumulatorii;

Orasul luminilor – no comment, doar un link: Paris – 26 gigapixels si o fotografie.

Dresden – 26 gigapixels

Captured in a series of 1655 images taken with a Canon EOS 5D Mark II camera, a man by the name of Holger Schulze captured a 26-Gigapixel photo of the cityscape in Dresden, Germany. The camera used a 400mm lens and was mounted on a motorized head to take the shots over nearly 3 hours.

The computer that processed the RAW image files had 16 processors and 48GB of memory. It took approximately 94 hours to stitch together all the shots into the massive 26-Gigapixel image. You can see the entire shot, as well as zoom around the cityscape, at this website: http://www.dresden-26-gigapixels.com/dresden26GP
