Flash Photographs

60mm at f5.6
60mm at f5.6 should yield less depth of field but you can see more background
55mm at f4.5
55mm at f4.5 should have less depth of field but you can see more background

I wanted to do a follow up posting to the one about Depth of Field.? I forgot to mention that as I learned when I started taking indoor photos with flash, depth of field can be affected by using a flash too.? Let me post a few example photos so you can see what I mean.? In the two examples above, the differences are subtle.? For example, the drag queen clawing at you, the only blurry area is the lower part of her dress.? That is closest to the lens.? Everything in this background is clear.? Also in the photo with male acrobats notice the man’s face on lower portion is blurry while the other face and the equipment on the left are clear.? The clapping hands are blurred too.? This result for f4 should have given slightly less depth of field.? My intent was actually to just get the stilted guy on top in focus and have the rest blurred.? To do that, I would have needed f2 or f1 and would have needed a longer lens and to distance myself from the subject.? The other challenge was the fog machine.? In clubs with a fog machine that makes a fake smokey environment, the flash often can bounce.? And thus you get less light in the exposure.? I guess I could go on and on about flash photography variables since this has become my specialty now but just ask in comments if you are curious about a certain scenario.

USA Wifi Hotspot Options

There have been some recent changes to the big providers of wifi hotspots, those which are not free. So here is an update with all currently available wifi options in the USA. I currently use TMobile which provided hotspots at all Starbucks, Borders, Fed Ex Kinkos, and some hotels and airports. However Starbucks decided to cancel their contract and change to ATT. Also Fed Ex canceled their contract for service. You cannot access wifi any longer at Kinkos locations. All Starbucks locations now are ATT Wifi spots. Tmobile customers will always have roaming access but the login process needs improvement. ATT contracted wayport, a third party provider of network access points. Most of the Starbucks locations have been successfully transitioned. But there are a few of them which either do not allow login properly or simply are non-functional. TMobile currently charges 19.99 a month (if you have cell service with them, otherwise 29.99).? Another solution for paid wifi access from a laptop, PDA, or any 802.1x capable device, ATT Wifi offers several locations.? ATT charges 19.99 for people who do not have their DSL services at home. If you do, costs are 9.99 or free depending on the level of broadband you have at home. The drawback I found to this option was that most of their hotspot locations (McDonalds, Starbucks, Hotels) were implemented with only a DSL line. Therefore if more than one person was using the location, speeds sucked. Another paid option is called Boingo. They contract with other providers(like ATT) to offer access from almost any paid location. See list below for rates and location info. If you just refuse to pay, there are many free wifi hotspots in most cities. These are usually at independent coffee shops and other places. Sometimes they are much less reliable or may be down since you never pay for them. Many major cities do offer free service at local libraries. These are reliable and usually on a fast backbone. The only exception to that which I have found is in smaller towns where the backbone is saturated or not high speed.? One last thing to mention, cell companies provide wifi access over their cell networks too.? You need to purchase a special proprietary card which usually is PCMCIA compatible.? Besides that cost, you have to join a yearly plan with monthly costs varying from 49 to 89 dollars.? This is the most expensive option.? It is usually only used for business users and services are paid by the employer. For information on these services, visit Verizon, Sprint, ATT cellular websites.? So in quick sum, options:

  1. ATT Wifi
  2. T Mobile
  3. Boingo Wifi
  4. Free Hotspot Locator

Hillary has not lost !

Me
Hillary Clinton has not lost the race just yet.? And I think if she does concede, Obama will choose her as a VP running mate.? Seems almost like a dream ticket.? Whatever the case, if one of them gets into office, the following problem would be closer to a solution.? Otherwise if McCain gets in, we are doomed to 4 more years of the same crap of GWB, Moron Deluxe. Yahoo News
