my photography

Here's some of my favorite pictures I've taken over the past few years not from film sets. Most were shot using a Zeiss 50mm,  a few with 17-50mm 2.8 and the last pic was taken with a 8mm fisheye lens.

cpm follow focus review

The first thing I noticed when I got the CPM follow focus is its size. Its a big follow focus and is kinda heavy which I really like. It feels solid and is well built using black anodized aluminum and blue anodized aluminum for the rail support.

The knob is oversized compared to other follow focuses and makes it really nice when shooting with a shoulder mount rig. When you reach for the follow focus to pull focus, the knob is very easy to find and adjust. If using a tripod the oversized knob can be marked with a dry erase marker for your focus points. Both the knob and gear turn smoothly. This follow focus has just a little backlash which is nice for a follow focus in this price range. It performs nicely in this catagory.

It comes with one supplied lens gear which is one of the nicest and easiest ones to put on and take off. The lens gear uses a zip tie method but it can be switch from lens to lens, unlike other zip tie lens gear that are permanent once applied. 

One thing worth mentioning about the CPM follow focus is that the gear isn't reversible. So when you are using smaller prime lenses, if you rack focus with your left hand, the gear is too far forward on the rails to reach the lens. The whole unit has to be switch over to the right side of the rails to reach smaller lenses, which isn't a big deal if you're used to using either hand to pull focus. 


Overall, I'm very pleased with the CPM follow focus. Build quality is what you would except for CPM which is very good, and you'll get great customer support from their team. The CPM follow focus feels and works like a much more expensive unit. If you're in the market for a follow focus I would recommend this one.

If using a shorter prime on the left the gear is too far forward

color space adobe and srgb

I visit numerous sites and blogs to learn about gear and settings on DSLR's and one thing I've never seen or noticed until recently is what color space to set your Canon DSLR to. I've always used the set color space on my cameras SRGB. Shane Hurlbut on his site http://www.hurlbutvisuals.com/ talks step by step on how to set up your Canon DSLR and color spaces. I found it interesting that he mentioned that he uses the Adobe RGB color space. So I decided to test both color spaces to see what I could come up with.

I shot with my t3i, Zeiss 50mm set at 1.4. On one card I shot on Adobe color space and the other card on SRGB color space. Picture profiles used were neutral 0,-4,-2,0, Flaat 10n 0,-4,-2,0, flaat 10p 0,-4,-2,0, portrait 0,-4,-2,0 and on a few I set everything to 0 except adjust skin tone one click to red.

When editing,  I start out in Vegas Pro11 and grade in Magicbullet Looks2 and noticed either something wasn't working in either both or one of the softwares. In Looks 2 my normal grading, which is adjusting the curves, adding contrast and the 3 wheel corrector, none of the adjustments were doing what they usually do. All the adjustments were just washing out the image, also the scopes and waveforms weren't working  so I had nothing to go by to tell what was actually being done to the footage. When I clicked back in Vegas the image was totally different from what Looks was showing and far from ideal. Usually the adjustments made in Looks2 carry over into Vegas smoothly and accurately. So I had to make small adjustments in Looks and see what was being done in Vegas, this took a while to grade the footage. I got the footage close to where it needed to be as far as finding true skintones but it would of went a lot faster with the aids of the scopes and waveform.

Even though the grading was done by eye and clicking back and forth to each program I will have to say the Adobe colorspace on all the picture profiles look nicer both in skintones and overall color. I will now be using the Adobe color space for all my shoots. As far as picture profiles I'm stuck between neutral and the Flaat 10p profiles, they both produce really natural and pleasing skintones and colors.

Once I figure out what's going on with the editing software I will reshoot the footage and grade properly to get a better examples of each. 

Here's an example of what was going on in looks2 and Vegas two same grade but two different images

Bargain condition lenses "Olympus"

I just got a Kowa 16h anamorphic lens and I wanted to see how wide I could go on the taking lens. I needed lenses with a small front filter thread to fit onto the anamorphic clamp. Zeiss contax mount lenses would of been my first choice but since they are around $300 dollars for one and only being a f2.8 lens, I decided to look for some cheaper alternatives. 

I looked at a few different brands I already owned and most of the 28mm and 35mm were out of stock or they only had one or the other. So I looked at Olympus lenses, and found they had both the 28mm and 35mm in stock but they were what Keh calls "bargain condition". Bargain means 70-79% of original condition. They may show more than average wear for the age of the item, or may have dents, dings and/or brassing and finish loss. The glass may have marks, anomalies and/or blemishes that should not affect picture quality. So you basically get an ugly lens that performs.
At first I was hesitant to order a lens in this condition but for the savings I got 4 Olympus lenses for just over a hundred dollars, 28mm f2.8,35mm 2.8, 50mm 1.8 and a 70-200mm 3.8.

I received the lenses quickly and looked them over and to my surprise they pretty much looked like a lens they would offer in better condition. All the lenses had finish wear. None of the lenses had cleaning marks or dust. Only the 28mm had a small little ding near the front filter thread. Not bad for the money I spent. Also the 28 and 35mm were very small in size which makes them easy on packing and makes for a more stealth look if shooting in crowds.

I decided to do a quick test to see how the color and bokeh looked compared to a few of my other lenses. Zeiss 50mm 1.4, Pentax super takumar 50mm 1.4, Canon 50mm 1.8, Samyang 35mm 1.4 and to cover all three a 17-50mm 2.8 zoom. 
All shots were set to standard profile with everything set to 0. No grading was done so as not to effect the final image. Iso for all f8 shots were at 160 and iso for all shots 2.8 and faster set at 100, with these I used a lightcraft nd fader. 
At first look it seems all the lenses colors are pretty close, except the Pentax 50mm has the yellowish tint due to its coating which fits what I was shooting giving it a nice vintage look. 
Overall, I'm pleased with the Olympus lenses. They are small, have a decent f stop, bokeh looks pleasant and the 28mm and 35mm focus down to well under a foot for close up type macro shots.  If you're looking to get a lens to fill a certain focal range, or start a set of the same brand, don't hesitant to look at the bargain condition labeled lenses.

Flaat picture profiles reviewed

Ever since I started shooting 2 years ago with my first Canon DSLR, I've always used neutral 0,-4,-2,0. Unless I wasn't going to grade the footage I would use the standard profile. Shooting neutral set at 0,-4,-2,0 has always made for a nice flat image that gives plenty of room in post to grade and get a nice looking final image.

Last year a few different picture profiles came out that could be downloaded on to your Canon DSLR. The one everybody talked about was Cinestyle. Cinestyle is supposed to give the flattest starting image out of all the profiles. I held off to see how others reviewed Cinestyle. Most liked it but said that it was an over all noisy image after grading. I have never used it because my editing software didn't have the needed lut curves to recover the information from Cinestyle profile. 

I recently heard of another profile called Flaat made by Samuel Hurtado known by @Simillaar on Twitter. He made his profiles off of Canon's preset with his own added touches and best of all they can be graded without the lut curves, so any editing software will work with Flaat profiles.
Flaat profiles are set to give less noise in the final image over other profiles, and ease of grading for skintones. There are 2 sets of picture styles one based off the portrait profile, and the other neutral. Both sets have their pros and cons. The portrait set has color shift issues. Blue tones tend to go a little heavy on the  cyan side, but overall has better skintones. The neutral set was made to avoid this color shift but the skintones don't turn out as nice.
There are four sets of each.
Flaat 09 gives 9 stops of dr
Flaat 10 gives 10 stops of dr much like Cinestyle
Flaat 11 gives 11 stops of dr
Flaat 12 gives 12 stops of dr but can be noisy
I choose Flaat 10n and Flaat 10p
 You can find the Flaat profiles here

I had just gotten a Kowa Bell & Howell 16h anamorphic and I wanted to try it out and decided to give the Flaat profiles a go against what I've been using neutral 0,-4,-2,0.  I set both Flaat 10n and Flaat 10p at 0,-4,-2,0 also.
I shot using all three profiles on a Canon t3i with a Jupiter 9 85mm taking lens and the Kowa anamorphic lens. I used lightcraft nd fader when I stepped down to f2 and my Smallhd dp4 for framing the shots. The last three images I removed the fader nd and shot at f8. All three profiles start off with a flat image looking close to each other.
After all the footage was shot I began to edit in Sony Vegas pro 11 to get a timeline and graded in Magic Bullet Looks 2. I used a basic curve,contrast and 3 wheel color correction for all the clips. The curve adjustment for all were the same and I added the same amount of contrast to the clips. All the clips grading wise were very simialr in how I had to apply  the color correction to each to get the vectroscope get to the upper third of the wheel  known has the skintone line. Also with looks 2 there's a skin overlay which shows little dots over the person. The more dots the more the colors are corrected for skin color.

Neutral is easy to grade to get to the skin tone line in the vectroscope. And the image looked close to my subjects skin tone which is fair. The bokeh seemed to stay alittle flat but i wasnt graded for an overall image just the skin tones.
Flaat profiles are just has easy to grade. I applied close to the same correction to get the vectroscope where it needed to be.
Flaat 10n once graded for the skintone line ended up with more of a yellowish tint on the skin. But seemed to have more overall color in the image compared to neutral.
Next was Flaat 10p once graded for skintones gave a nice overall image. The skin color looked very good and the over all image looked nice and more colorful. 

Here are the frame grabs of each. I noticed once rendered there was a color shift in the images making them more contrasty and yellowish.

I decided to shoot around the back yard to see how each would grade and to see if there was a shift in color once rendered.
I shot 2 different images both 3 times with each of the profiles. Neutral, Flaat 10p, and Flaat 10p.
All clips were graded the same, I applied the same curve adjustments,contrast and color correction. The color for all 3 look very close. The only difference is the flaat profiles have a brighter overall image.
There seemed to be no color shift after rendering these clips.

After shooting with the flaat profiles I really like the image that flaat 10p provides. It gives a nice image in regards to skin tones and a brighter overall image with nice colors in the highlights and shadows. If your looking to try a profiles that doesn't require a lut curve or one that doesn't add extra noise give the flaat profiles a try.
