hintheman website with iWeb

2009-06-30
I managed to use iWeb to update my website within few hours of effort. There is minimal programming needed. I have not even touched a single line of HTML or JavaScript code. It is both nice and limited in terms what I can do in the page. Most pages are done in the nature of selecting a theme and duplicate page elements. I have used both the Flickr slide-show and that of Pictobrowser to compose Galleries. And I am experimenting similar slide-shows in the Portfolio section.

And I make use of Wowzio rss widgets to serve as a digest to my own authored blogs in Hin's Photo Blog and Hin's Tech Corner. I am thrilled with the results but I am a bit unsettled on the website for several important elements that are quite lacking in iWeb. Here are few of them:
  • No provision for sitemap.xml -- this will hamper search optimization
  • No editing option to add meta tags into html header
  • No support for guest book
  • No notion of a common header and footer where I can enter statcounter code properly
And here are few places that I have either found a solution and find tools and links that are worth visiting for iWeb related topics:

Back Lighting with Pentax DA* 50-135mm f/2.8

Pentax DA* 50-135mm is my go to lens when it comes to visiting beach in the weekend. I have forgotten to bring in my flash for fill-flash for earlier scenes when the sun's overhead position creates lots of shadows on portraits. When I see the back lighting scenes, I am all happy.

While in the beach shooting some dogs portraits with Mervy, I find a lot of missing bird shot opportunities due to the lack of rich in the DA* 50-135mm zoom. I love the DA* short zoom and I am thinking of the possibility in getting Pentax DA* 60-250mm, I would have made more shots with both the dogs and the birds in the visit if I have that longer reach to 250mm.

I should have brought in my flash for the fill light to lighten up the shadows on the face.

Tamron Adaptall-2 P/KA Adapter

2009-06-23
Tamron Adaptall2 P/KA adapter

Tamron Adaptall2 P/KA adapter
I have two copies of this P/KA adapter that works with Adaptall-2 lens. This PK/A can work with Auto aperture with Tamron adaptall-2 lens. My most recent copy is a brand new one. They are more expensive than the P/K adapter as they allow the Av mode saving the extra step in stop-down meterring. Though more expensive and harder to find a good copy to purchase, I will recommend this adapter over others.

There is one common caveat that happen to these PK/A adapters, I have problems with loose connection with both copies where the actual apertures in Av mode is not displayed and the maximum aperture that I can select in e-dial only goes to f/4.0 and not anything bigger. My first copy of the PK/A adapter refuses to go to f/3.5 for my 19AH zoom and I can't select f/2.5 for my 52BB macro. After many trials of cleaning the contacts, I gave up on my 1st adapter and sold it to others with full disclosure on the problems.

Many have reported to similar problems. Some reported success to perform minor scraping of screw heads with either a sharp knife or sand paper on the adapter. I have taken many trials and my problems is not totally gone as my problems of disappearing F/aperture still happens intermiddently with my 2nd copy of the adapter. The scraping may improve the connection between the electrical contacts with those in the K mount. With my 2nd copy, I manage to select f/3.5 for the 19AH zoom.

Many thought that there is a thin film of coating on the adapter that prevents the accurate connection with the electrical contacts. Others suggest a inaccurate mounting design that give rise to the loose connection. I still find occasional need to wiggle the lens mount to see the LCD display of the f/aperture in Av mode.

It is very unsettled to get an adapter that only goes to f/4.0 and I am yet to use the trick of adding a small piece of aluminum foil in between the adapter and the K mount and see if it improves the connection further.


Updates:
  • I found remounting the adapter sometime do help with loose connection
  • In the case of aperture displayed as "F--" on the top LCD display, a quick wiggle in clockwise direction seems what it takes to fix the problem
  • For aperture that goes only to f/4.0, I found using a sand-paper or something that is safe to scrape off the thin films covering the electrical contacts on the adaptall-2 mount the most effective.
  • For lens at f/3.8 maximum aperture, the display in Av aperture can only go to f/4.0 and I think that is not fixable unless you change to M mode and use stop-down metering.
  • Contrary to what I say before that adding a thin aluminum foil as in M42 mount to get focus trap enabled, I was not able to improve the electrical connection with the adaptall-2 adapter in using foil.
  • A great tip that I have learned and found extremely useful in easing the dismounting: remember to set aperture to smallest using the black tab before engaging the silver tab for dismount.

Spectra Light Flash Diffuser

2009-06-11
As Diffuser

Spectra Light Diffuser
In the above picture, I should have turned around the diffuser along the flash side to yield more coverage over the flash-head. Also, I should keep a bigger space in between the flash head and the diffuser. I used this position for straight on flash while the translucent panel serves as a diffuser


As Bouncer, Diffuser & Reflector
Spectra Light Diffuser
I look for a diffuser to be used with the Pentax AF540 flash. I am pretty new to using flash but I find flash a necessity to make the shot clean. I like natural looking picture and hence I long for an easy to use bouncer and diffuser. Also as an amateur to flash, I experiment on using flash bouncing light with light color wall and roof. The caveat that I found in flash bouncing is in not finding a nearby light color wall and roof. And I found this gadget with Spectra Light comes in handy. Its design and look is intuitive and easy to experiment and learn with.

I don't have in-depth experience with other diffuser such as Gary Fong Lightsphere and hence I don't quite know how it compares. But one thing is for sure, the Spectra Light is inexpensive to get as I paid roughly $15.00 in ebay. And I used it in first shooting with my niece graduation and it helps the newbie strobist in me, giving me more confidence into fill-flash with a natural looking pictures.

Golden Panel next to
translucent panel
Spectra Light Diffuser
Spectra Light Diffuser comes with five panels and a pocket holder:
  • The translucent panel is used for flash bounce and diffuser
  • The golden panel is used as a warming reflector. It comes with a sticky label on back that one can peel out and attach to the solid white panel.
  • The silver panel is used as an intensify reflector. It comes with a sticky label on back that one can peel out and attach to the solid white panel.
  • The two solid white panels can be used for bounce serving as a 4x4 solid panel redirecting light as a nearby wall or roof. Unlike the translucent panel, no light will go through the pane.
  • Depending on your choices, I learn from Russel to attach the gold label to one side of the solid white panel and attach the silver label to the 2nd solid white panel. In that arrangement, I can have an alternate white panel to go with a colored panel in silver and gold color. Sweet arrangement for multiple strobes.
And I kind of like the design in the ball-head that allow me to move the panel quite freely in the vertical and horizontally.

Spectra Light Diffuser
I have used the gadget as a diffuser and bouncer using the translucent panel in my niece graduation ceremony. So far, I am quite satisfied with the assistance that Spectra Light offers to help bounce and diffuse light from my flash. Results seems consistent as if no flash is used.

Impressions & Notes
  • A good value for $15.0 in purchase cost from ebay
  • Very effective in use in outdoor as a fill-flash bouncer and reflector.
  • I think the golden panel will serve well as a warming reflector. I have not used it to confirm as I mostly used the translucent panel
  • Indoor using the Spectra as a diffuser to cover the flash head directly and aim object straight on still has that undesired flashy look that I try to avoid. I need to experiment with lowering flash strength and flash compensation. I prefer the indirect approach bouncing light from the panel tilted at an angle instead.
  • I am experiment strapping the diffuser Velcro strap on lens and use the diffuser for the built-in flash. It may work but I am yet to test it
  • Lightweight
  • Easy to adjust angle for bouncing flash.
  • Partial light reflected from translucent panel helps in reflection.
  • With the golden and silver reflector, I expect adjustment needed for the flash strength to one's liking.
  • I buy it from this store called discountbulbs in ebay for $14.56 plus shipping

Carl Zeiss Jena Sonnar 180mm f/2.8 (m42) -- 2nd copy

2009-06-10
I finally have some product shots of my 2nd copy of Carl Zeiss Jena Sonnar 180mm f/2.8 in M42 mount. The lens comes with a Pentaxcon6 to M42. It is in great cosmetic condition.

I recently took it out and have a Friday morning date with my wife over coffee. The lens is similar to my 1st copy. I lose the focus trap and in many test shots, I have off focus errors and I will try another time adding a small piece of aluminum foil around the lens mount to enable focus trapping.

Impressions & Notes:
  • A bit heavy for a 180mm lens. Last time I check on it, it is about 3.5 lb. This lens does take some time to get used to. I thought it is too heavy to carry around it for long but I was okay in the shooting. The lens is actually short and bulky. Compared to my photosniper, this lens is easier to handle as it is shorter in length and I don't get pulled down in shooting in an horizon
  • The lost of focus trap leads me to some focusing errors
  • I have been shooting straight in Av mode. In f/2.8, I find that I need to +0.3 to +0.7 for Ev compensation
  • Sharpness is decent for this lens. When I stopped down to f/8.0, color and contrast are better.
  • In 180mm focal length, shallow DOF seems to help isolating the person better from the blurred background.
  • Minimal focusing distance is about 5.5 feet and 1.7m
  • Weight is 3.5 lb
  • I don't have a filter on the 2nd copy and I would guess about 82mm in filter size.
  • It is difficult to carry this lens in my current backpack.
  • I hesitate in selling this lens as it is a sheer beauty to use. Unless I can put it into good use, I feel the guilt in having it in my gear list not frequently used.

Sigma 17-70mm f/2.8-4.5 DC Macro in Japanese Tea Garden

2009-06-09
I took the Sigma lens out for a family trip in Japanese Tea Garden. The sigma satisfy my occasional need for wide angle and it is a great family outing zoom lens covering the most critical focal length in one lens and with a 1:2.3 close up. I call it my best walk-around lens.

Sigma 17-70mm f/2.8-4.5 DC Macro in Japanese Tea Garden


Impressions & Notes
  • Lens is smaller and lighter than Tamron 28-75mm f/2.8 and hence more easier to pick for family weekend outing with kids
  • The close up in 1:2.3 turn out to be great in visiting places with flowers
  • The wide angle covers the occasional need I have in wide landscape
  • While overlapping in usage with my Tamron zoom, the sigma still has its places as I tend to choose it over the Tamron for family outing in weekend.
  • For portrait shooting, I will prefer the Tamron for its constant and faster speed
  • The vari-focal apertures from f/2.8 to f/4.5 don't bother me in actual usage. When light is dimmer, I will just widen up to the shorten end of the zoom
  • Use of built-in internal flash incur quite a bit of high-light overblown in the shooting. I need a diffuser for the built-in flash. I know I have used film canister to some success but I will think a better built diffuser is a welcome addition to casual flash usage
  • It is my best walk-around lens with a critical focal range

Pentax DA 35mm f/2.8 1:1 Macro Limited On Flowers

2009-06-08
I have been using my 35mm limited mostly for product shots. It is smaller than any other of my macro lens and it is easy to carry it along with other lens, hence It has become my go-to macro lens for product shot.

Last week, I came to try it on flower going from 1:2 to 1:1 close up distance. I am very happy with the performance. It is quite easy to use. When it got close to 1:1 scale, I have to use manual focus. I did the test shots not in the best lighting and I expect the lens to perform better when I manage to shoot again with better lighting. It missed the quick shift focus as in the DA* lens but manual focusing is very capable with this lens

Impressions & Notes:
  • Lens has beautiful color and contrast
  • I see better sharpness with 77mm limited but I have no complaint for the 35mm.
  • Close up from 1:2 to 1:1 is quite easy to make on this lens
  • Manual focus missed AF/MF switch as in DA* lens but manual focusing is found pleasant in the 35mm. It is about half turn in the focusing ring.
  • Quick shift focus is allowed in overriding the AF when manual focus ring is turned
  • One big gripe that I have on 35mm limited is the lens cap. When I have a filter mounted, the lens cap no longer fit tightly with the lens
  • I was initially not aware of the presence of a lens hood. One has to pull the lens hood from the side.
  • This is a great lens to be used for product shots, close up and perhaps street shooting
  • I see a great number of samples using it for documentary work and black and white photos. I will use this lens for street shooting and hopefully find the time to use it for b&w pictures.
