Streets of Omaha

This was done basically as a spoof ala The Sopranos series intro with additional footage for "seasoning".

My friend, actor Jerry Murray, drove with me around some of the streets of downtown Omaha that resemble in a bit that New Jersey look, so to speak. Shot some city landmarks along the way.

Done in HD 720p at 24fps using the HVX200 with the Letus Extreme and Canon / Nikon 35mm f/2.8 zoom lenses and primes.
Timed in After Effects and film-looked with our Proceso Cinematico Digital-PCD.

Nikon D90 - a new toy in town

Now this is a nice transition for all pro photo and video lovers out there.

I consider myself so much into capturing moments and freezing memories for life. And if they are in "motion", the better. Sadly, few cameras feature extreme quality in both worlds of still and moving photography. I guess with this new baby out, this is gonna end and a dream will come true.

Enter the Nikon D90 12.9 (12.3 effective) Megapixel Digital still camera WITH 720p HD video recording! Yes folks, this new thing can record at 720p at 24fps. No more of those aweful quality 640x480 VGA lousy videos captured with your still cam. Of course, as one would assume, it doesnt stand up to the professional digital HD camcorders out there but it still is a great progress in the arenas of the digital HD world (I wouldn't trade my HVX no way!).


There's a new CMOS sensor and according to the Nikon press release it's D300 quality output all the way up to ISO 6400 and one thing being borrowed by the higher end models is the awesome 3.0-inch VGA screen as the D3/D300. It also has a Live Preview function and the needed dust removal option too. Another awesome feature is its HDMI output for the video!!....but i'm sure it has some drawbacks. There's no free lunch, u know, and as I compare and see, there's a lot similar to the D80, though there is a new shutter and 3D tracking AF seen on the D3/D300.


When I checked it out, the D90 is very similar to it's ancestor (the D80) and it looks to me more of an upgrade more than a complete new model replacement of the prior model, but what will really catapult this one to be a fav for many amateur and prosumer user will be the 'world's first' DSLR movie mode. I certainly wouldn't recommend to use it to make your films, of course, but what I saw was that -having the CMOS sensor and the use of 35mm lenses- I could have that depth-of-field so loved by us filmmakers. The holy grail of our "religious" motion-picture career without the need of any expensive adapter.


So, in brief, the camera has this features:
  • 12.9 megapixel DX-format CMOS sensor (effective pixels: 12.3 million)
  • Dust removal system
  • Bigger, better screen (as D3, D300)
  • Live View with contrast detect AF
  • Movie Mode
  • Wider ISO range, upgraded AF system (3D tracking, face detection)
  • Active D-Lighting, vignetting control and extra retouching options
  • Automatic chromatic aberration correction
  • Picture Control presets
  • Faster continuous shooting and larger buffer
  • Pictmotion slideshows
  • 3.0-inch 920,000 pixel (VGA x 3 colors) TFT-LCD (same as D3 and D300)
  • Live View with contrast-detect AF, face detection
  • Image sensor cleaning (sensor shake)
  • Illuminated focus points
  • Movie capture at up to 1280 x 720 (720p) 24 fps with mono sound
  • IS0 200-3200 range (100-6400 expanded)
  • 4.5 frames per second continuous shooting (buffer: 7 RAW, 25 JPEG fine, 100 JPEG Normal)
  • Expeed image processing engine
  • 3D tracking AF (11 point)
  • Short startup time, viewfinder blackout and shutter lag
  • Slightly improved viewfinder (96% frame coverage)
  • Extensive in-camera retouching including raw development and straightening
  • Improved user interface
  • New optional compact GPS unit (fits on hot shoe)
  • Same battery and vertical grip as D80
  • Vignetting control in-camera
  • 72 thumbnail and calendar view in playback.

This new camera defintely is one to check (or to own for some serious photographers that would need the 720 HD feature). All in all this one is a serious contender to many still cams out there and for about $1 K (body only) its quite cheap for a model with this features.

UPDATE: It seems that some users have seen some "funny features" on this camera. The CMOS sensor has some serious issue that is skew: slow-read reset of the sensor and the results are some type of "funny" elastic motion like jelly shaking. Here is a video test I found on the net that shows it.

Filming the Alter Ego video

So finally....the Utopía videoclip was shot on monday.
The day was packed with details that made it a frenzy one in production anecdotes.

Lighting took quite a while as the place was big and the main power box was a bit far from the shooting sets. We had a late start and had to push my singing shots to the end of the day and overrun our schedule ending time by three and a half hours. We wrapped for the day early morning the next day. Besides of that, it was good to see all the band together after years of being apart.

Establishing shots were done in 720p at 24fps using a Canon EF 16-35mm f/2.8L USM, medium and tight tele shots were done with the Tamron SP AF 28-75mm f/2.8 XR Di LD and Nikon 80-200mm f/2.8D ED AF zoom lenses all using the Letus Extreme.
The HVX200 delivered beautiful colors and details but had to lower the V-detail a bit to get rid of the "video" sharpness and get closer to film edge-quality.
Tried far to hue the colors in-camera as not to overload post-production and rendering times. So far, on today's tests, it's giving me five hours per minute of video.
The Jib-arm bringed those floating shots I so love and raising up to 12 feet, it sure brought production value to the shots.
As always, my good old friend Aguinaga was with me on the lights and it was a good thing to work once again together after so many years and like on every job, he is quite ready for light directions I might have. Most of my latter work was done with him under and I must say he is not only a great professional but a great friend.

Here are some pics of the shooting.
The second day of shooting will be on the weekend.


Here below is a first color grading test of random clips from the video.

Nikon zoom fixed again

I took the Nikon zoom lens for repair and the guy did well. He dismantled the whole lens in parts and found that the problem was the the Manual/Automatic switch: it wasn't clamping well enough and it became loose, leaving the focus ring to spin freely without engaging the focusing internal motors.
This was the ofending part: The switch that didn't clamp well.
I have another Canon 35mm f/2.0 Prime lens that the focus ring didn't work as well. Dismantled the whole thing also.
It seems that it has the internal spining mechanism broken. I bought it refurbished in the US and I still have the warranty but it's too much hassle having it sent there, paying shipping and waiting for weeks to have it fixed, so just went ahead and took care of business myself. The guy sure seems to know what he's doing. Gotta pick it tomorrow though.
I just hope the Nikon lens doesn't become broken again and this time its fixed for good.

UPDATE: Went to pick up my Canon 35mm Prime and it works fine at last. The Nikon zoom lens is not giving me any problems either. Hope it stays that way.

Got the Nikon zoom lens

Finally...the Letus Nikon Lens Mount has arrived. Customs agents gave it clearance today but it was to be delivered tomorrow. I couldn't wait so I drove like 60km to Fedex's main office to pick it up. Then, off to get the Nikon lens. The guy was just finishing cleaning it up for the sell and it looked good. Now the focus barrel was better (but not smooth yet). I tried it a couple of times on the camera kit with the Letus Extreme and it worked pretty well: no vignetting on wide apertures, nice beautiful bokeh at 2.8, sharp, no scrathes and good contrast. But the focus ring got stuck once so the dealer gave it to me for some days to test it without buying it yet to see if it worked for me. So far, already installed with my HVX200 kit at home, the focus ring got stuck and doesn't move.
Tomorrow I'm taking it back for repair. This time it has to work. It is the best bargain ever and this Nikon zoom is quite solid and rigid and together with the Tamron 28-75mm, I really have a good range from wide to tele. I really dont want to let this lens go.

Found a bargain Nikon zoom lens

I bought a Tamron SP AF 28-75mm f/2.8 XR lens a month ago. I guess it was second hand but it looked like new. The quality of the picture is quite good and decided to buy it after reading some reviews. But Im kinda short on the far end of the zoom range. I cant get tight shots from far away as 75mm isnt enough so I need to go shopping.

Some days ago, while searching for weeks for fast zoom lenses on a local market (cant go higher than 2.8, the Letus eats up 1/2 of a stop) I found a nice little (big actually) Nikon 80-200mm f/2.8D ED AF lens. It looks amazing! It's condition was quite abused (the focus ring was loose, the zoom ring was jerky and it stuck often) but it looked repairable. Besides, the price was tempting (less than 1/4 of its actual price new) and it seemed repairable. So I told the guy if he could have it repaired and if done well I'll take it. He agreed.
That lens is really huge. Almost the size of the Canon XL 16x II, and the good news it can keep a 2.8 stop in all it's range. It can also go down to 22. I checked the glass under bright light and I didn't see any scratches and dont detect any aberrations either.

I called the guy yesterday and he has it repaired. Im just waiting for the Nikon Lens Mount from Letus to arrive tomorrow to have that huge lens installed on my cam rig!

It's quite a bargain...I just hope the repair is not just a momentary "make-up" and down the road in some days it starts falling apart again. The place doesn't offer a warranty.
