    I just got my Nikkor 50 f/1.4G and I love it. It is fast focusing – much faster than the f/1.4D, it does not seem as fast as my 24-70 f/2.8 which is strange as it is longer/larger lens. The best part of it is the creaminess and beautiful contrast. It reminds me of Canon’s 85 f/1.2L II lens – which I loved! The Nikkor version is way faster focusing though.  In summary, the focus is fast, not blazingly fast, the bokeh is rounded and the out of focus areas are creamy.

     

    Creaminess at 1.4 and sharp where it needs to be:

    Rounded bubbly bokeh:
    Happy New Year!

    As a comparison, here is the 1.4D at f/3.5 notice the more edgy bokeh:

    After over a week of fun with a rented 5DII (review upcoming), I played with my almost one year ‘old’ D300.

    Today, I played with the “Live View” mode and setting the white balance. Live view is a great resource to get direct visual feedback on different white balance settings as you can see the scenery change on the LCD in real time.

    Live view is really easy to  use – just turn on live view then while viewing the scenery on the LCD you change the camera settings and get direct feedback of the effect of changing camera on the camera LCD screen/monitor.

    (1) Turn on live view (use the camera dial under the ISO/QUAL/WB buttons – same dial where you set shooting mode – single/remote timers and set it to Live View (Lv).

    (2) Push the shutter release button down once – now live view is activated.

    (3) Look at the LCD screen and compose the image or change setting such as WB and

    (4) push the shutter again and hold the shutter to take the shot.

     

    Turn on Live View by moving this dial to Lv

    The Secret Workshop is a photographers’ workshop focused on child photography hosted by Cheryl Muhr. This is my review of the workshop I attended in June, 2008 in Flint Michigan.

    Cheryl is a fun person to be around. She has managed to integrate her business into her family life, she treats life and her profession as a hobby, as something to live and strive for. Her motto is that if you don’t enjoy something — get rid of it and maximize the fun factors in life. Cheryl is a joy to listen to and she keeps your attention. Cheryl’s enthusiasm made the workshop inspiring and helped me to see things in a new light.

    This is not just a motivational workshop, it also teaches you how to price yourself and your work; get clients in different target markets and how to break into new areas of the photography market (commercial, editorial and portraiture). She also covers portrait photography and processing techniques.

    The Secret Workshop is a two-day workshop:  One “secret” about the workshop is that you don’t know who the guest speaker will be before you arrive. We were treated to Brianna Graham, a Grand Rapids-based photographer.

    The first day began with a lecture by Cheryl about how she broke into the business, what inspires her and her philosophy on photography. It was followed by a presentation by Brianna Graham where she explained her lighting and studio techniques. She did not discuss her post-processing techniques.

    The first day ended with a two-to-three hour shoot-out. 15-25 child models were shared among 45, mostly women participants (there was one male). We were split into groups by table – so we ended up with about 5 groups with 7-8 women/men per group. This part of the workshop was also the weakest – it was chaotic - the jungle law ruled: eat or be eaten – you had to recruit the models on your own – if there was a free and un-tired one, pose her or him and then get your shot. Each group was on their own practicing their skills.

    In retrospect, for this part, the most valuable way to spend your time here is to stalk Cheryl or linger at Brianna’s studio shot station and to forget about getting your shot. After all - I was there to get a good sense on how to create an image from their point of view, what to look for (in terms of light & setting & pose) and how to reach a final product.

    The final day was about post-production, setting up a business, including pricing and selecting supporting products or companies (printing companies, accessories and more). Cheryl illustrates her technique with images she shot from the day before and accommodates her thought process in creating them.

    As with any workshop - there were a few weaknesses: My chief complaint is that it was too crowded. 40+ photographers are too many for the price of the workshop and there is really no one-on-one time with Cheryl. The crowdedness is especially a problem at the shoot-out session. The workshop could probably improve if the models had certain tasks or stations – and a rotation scheme was implemented. I suspect that this is not unusual when you have a number of models and photographers. But despite the somewhat chaotic shootout and difficulties overall the workshop went smoothly. Second – I think it would have been nice if Cheryl attempted to spend some time per group – this could mitigate the need for one-on-one time per participant. Most of us left the workshop wishing for more one-on-one time. However, Cheryl had recruited a number of volunteers from previous workshop and they were at hand. I appreciate that forethought. Amanda – was especially helpful.

    The workshop concluded with door prizes and awards – two of them were Blu Domain web sites (OH and I wish I had won one of those) – there were some actions sets awards (Nichole Van and MCP Actions –and Jodi of MCP actions was an attendee) and other awards. We got a goody bag with coupons, a workbook with the stuff we covered (slides) and a CD that includes pricing and Cheryl’s workflow actions.

    My results – despite the period of chaos during the model shoot-out – were several nice images. I also came out of the workshop feeling more confident in my photography and that I could start a photography business if I wanted to. But for now I am a hobbyist – so that aspect of photography will probably not be for a while. The pricing and strategies in setting up a business was valuable, however. Cheryl’s greatest strength is that she inspired you and she creates a positive atmosphere just to be there – and that in it self is priceless.

     A Diebold Touchscreen Voting Machine.  

    I recently went to a talk on voting machines by Barbara Simons, a computer security expert from Stanford who is spearheading an investigation of the problems of these machines. I also had a one-on-one talk with her on this upcoming election. She has been involved since at least the 2004 election.

    Here are my thoughts resulting from our discussion and her talk: This is an important issue and it is of-course not a partisan problem as it affects both sides and our freedom to vote and impact the election. There are several problems:

    • Monopoly:  Only one company is in control of these machines  - no competition to drive up the quality of the hardware of the machines or the software that drives the machines.
    • Unverifiable Results: The software used is proprietary to the company that supply the machines: less control, less opportunities to verify the results or that the software works correctly. Worse the company refuses to have their software evaluated and verified by computer experts. The machines are also paperless which magnifies the problem, i.e., recounts are difficult if not impossible as there are no verifiable paper records. There are numerous examples of the problems caused with these unverifiable machines.
    • Security Holes: The software is plagued with errors and security holes. The company inadvertently released a beta version of their software in 2004 (I believe by an employee / software developer) on a bulletin board. Computer scientists found serious problems of this version and demonstrated that the software is easily hacked due to poor software practices.

    I believe that a solution is to publically release the software; releasing it allows it to be scrutinized by experts and consequently improves security and reliability. Promote competition in developing the technology of the machines: Allowing competition in both producing the machines (hardware) and software improves the quality of the software and machines. And I echo David Dill’s of Stanford sentiment when he said, “Our democracy depends on our having secure, reliable, and accurate elections.”

    Nikon D3 at Amazon
    Nikon D700 at Amazon

    The D700 or the D3, which one should I get?

    Image quality wise there are no perceptual differences between the D700 and D3. There are four primary differences between the cameras: (1) length of life (2) processor speed (e.g., impacting frame rate) (3) size/ergonomics and (4) the D700 has an on-board flash.

    The D3 is more of a heavy-duty camera – it is more reliable and has a greater shutter life (150,000 vs. 300,000 actuations) so it will last a lot longer. I can see this as a big seller for pro-photographer, but for amateurs, like myself, probably not as much as we will probably upgrade to a new camera before the camera’s demise. Alongside this pro-advantage – the D3 has dual memory slots. But hey –

     us amateurs can get bigger cards - 32G cards are becoming quit reasonably priced.

    The D3 has a dual processor giving the D3 more power and speed –

     it can achieve a frame rate of up to 9 frames per second. The D700 achieves 5 fps with its single processor, but with the MB-D100 battery grip with AA batteries it offers up to 8 frames per second. The D3 has a slight edge as it goes to 9 fps but in practice this is not really noticeable. With the battery grip the D700 is bulkier, larger and heavier than the D3 and not as ergonomic - again ergonomics is a factor for heavy-duty hardcore shooters.

    Another advantage of the D3 is the 100% viewfinder coverage –

     the D700 only has 95% coverage.

    The D700 edges the D3 on having sensor cleaner and as a smaller & lighter travel camera, it is lighter on your wrist but the trade-off (without the battery grip) is focus acquisition and frame rate.

    In summary the choice boils down to a function of price versus wear, so for the price of one 2008 D3 ($4,540), you may get a 2008 D700 ($3,000 + $240 grip) and a 2010 D800 with newer technology - so the question is within that same time span do you want (need) the D3? But of-course, it is just something about having the best Nikon Camera - and that is of-course the D3 (or perhaps the upcoming the D3x).

    The D3 difference:

    • 300,000 actuations (150,000 for the D700)
    • Dual memory card slots (vs. single on the D700)
    • 100% viewfinder coverage (95% for the D700).
    • No build in flash.
    • Better ergonomics.
    • No sensor cleaner.
    • Choice of a 5:4 image aspect option (D3 only)
    • Better battery life.
    • Frame rate 9 fps (D3), 8 fps (D700 with a battery grip), 8 fps (D300 with a battery grip).
    • Price $4,540 (D3) vs. $3,000 (D700) vs. $1,625 (D300).
    • The MB-D100 battery grip is $240.00.
    • .20 seconds focus and shoot with the D3 (vs. .25 seconds for the D700).

    Photoshop CS4 at Amazon

    Adobe announced their new photo editing suite, CS4 at Photokina.

    The primary differences between Photoshop CS3 and CS4 are the access to tools (curves, layers, saturation and more) and masking out objects directly by clicking on an image’s pixels. When the dialog is launched it accounts for the selected pixels by setting default values and selection points.   There are at least three reasons to upgrade:

    • An Adjustment Panel to access tools more directly by a point and click interface. You access the panel by clicking on the the photo itself (as opposed to getting to tools from to the layer interface). For example while you click on the image, you can directly access the curves dialog and it defaults to a starter point (tone) that is the ‘darkness’ of the pixel that you clicked on the photo.
    • Mask Panel - Easy access to masking functions (selections, feather, etc), again by clicking on the image - makes it easy to to selectively mask out selected objects.
    • Transformation Interface -  resizing and skewing the image is more direct and more immediate.

    Coming out in November — and I want to try these babies out! I would like to couple the Sony body ($2,999) with the Zeiss 24-70 f/2.8 ($1,800).  I think a good match for the Canon will be either the 85 f/1.2L or the 24-70 f/2.8.

    Canon 5D II
    Canon EF 85mm f1.2L USM Mark II
    Canon 24-70/2.8L 

    Sony A900
    Zeiss Vario-Sonnar 24-70 f/2.8 ZA
    Zeiss Vario-Sonnar 135 f/1.8 

    Sony 70-200 f/2.8G SAL
    Zeiss 85 f/1.4 SAL

    But not sure what lenses I should rent for my comparison. Leaning towards the Zeiss 24-70 f/2.8 - it got fantastic reviews. I would like something that is comparable to my Nikon lenses. I have the Nikon 24-70 f/2.8, Nikon 70-200 f/2.8 and Nikon 85 f/1.4 for my Nikon comparison. Nikon really needs to update their prime lenses!  Hopefully we will see some more coming out next week at Photokina.  

    Sony A900:
    Pros:

    • Full frame 24.6 megapixel Exmor CMOS sensor.
    • In camera stabilization system that works in practice.
    • Dual Bionz image processors.
    • 3K price tag (which is reasonable for this level of camera)
    • Takes the world class Zeiss lenses.
    • 9-pt dual cross focus centers
    • 5 fps continuous shooting (for up to 13 RAW frames)
    • USB 2.0.

    Cons:

    • Heavy 2.07 pounds (939 g) (but lighter than the Nikon D700)
    • Wish there were more focus points.
    • Noise even at low ISO 200, above 200 it is bothersome ):
    • No flash

    Canon 5D II (available November, 2008)
    Pros:

    • 9 cross-haired AF points - AF system have a slight improvement over the old 5D.
    • 6 non-addressable assist focus points.
    • Live View.
    • 21.1 megapixels CMOS sensor (old 5D was 12.8 megapixels).
      • pixel pitch 6.4 µm (old 5D was 8.4 µm)
      • New RGB color filters with improved transmission rates.
      • Cleaner images.
      • DIGIC 4 processor.
      • Canon claims highest image quality of any EOS digital SLR released to date.
    • Movie mode.
    • $2,699

    Cons:

    • Slow frame rate of 3.9 frames/sec
    • No flash.

    Reviews across the web for the Sony A900:

    http://www.photographybay.com/2008/01/13/sony-a900/

    Quote that puts the cameras (Nikon D700, Canon 5D II and Sony A900) into a nice perspective - from Mike Tomkins and Shawn Barnett article over at imaging-resource [cite link here].

    “Each of the sub-$3,000 full-frame digital SLRs offers its own unique strength. The Nikon D700 may “only” be 12.1 megapixels, but it can fire off eight frames per second, and has some very impressive high-ISO performance. The Sony A900 offers astonishingly high resolution, at 24.6 megapixels, and yet still cranks out a respectable five frames per second. And the Canon 5D Mark II has very high resolution of 21.1 megapixels with the added benefit of HD movie capture. Unless you need high speed capture, and a 30fps HD movie is out of the question, the Canon 5D Mark II appears to offer the best of both of its competitors, with high resolution capture and what we expect to be very good high ISO performance. Your needs and your lens collection will help decide which way you lean; the big story is that for the first time you have a choice.

    Imagine, any day now we may make a leap in understanding the universe better.

    The CERN particle collider, the Large Hadron Collider (LHC), just had his first successful test in getting ready to smash particles.

    Particle colliders have been around for a while (at least since the eighties)- and we got our own colliders here in the US, e.g., Stanford’s SLAC (a linear collider) and there are some circular ones - not sure where they are located (but one I believe is Fermilab in Illinois).

    What is different about Hadron, in CERN, is that it can produce enough energy to potentially generate a Higgs boson (if it exist)– we don’t know whether it exists or not. It is a weightless particle, or a particle with no mass.

    The boson is necessary to explain a lot of theories in physics, for example you may know about gravity and you probably know about mass and energy (Einstein), this boson would unify the gap between gravity, mass and energy. Cool and exiting stuff!

    What about the danger?

    Some people think it is dangerous because it may create a miniature black hole, and some say it will decay while others say it will suck in other mass and grow and ultimately we all get sucked in. However, Stephen Hawkins, you may remember him from his special appearance on Star Trek, says that the particle collisions even greater than the one anticipated happens millions of times in the earth’s atmosphere so there is nothing to worry about.

    I also would like to add that Hawkins also placed a $100 bet that the experiment will not produce a boson.
