>Question from ‘Danny Digital’

>I received this Question From Vimeo User Danny Digital regarding the Miny 35mm Vibrating DOF adapter from http://www.miny.tv/

Here is my Honest and Frank Response.

Conversation with Danny Digital
saw you got the miny 35mm dof. which one did you get and do you recommend it? 
Hi There. I ordered the Vibrating DOF with ACHROMAT. 

I wouldnt recommend any of them, it was of poor build quality and the ground glass focusing screen seemed as if it was about 20 Micron, had loads of noise on it (they custom make them and they are not very impressive at all when using high def cameras) The vibrating part, which is a motor with a small weight on the end (much like you would find in you PS2 controller) was not much better.The motor decided to spin at different speed Despite changing batteries a number of times presuming it was that!

The Motor then span out of control, so much so that the GG holder was hitting the side of the extension tube uncontrollably. Rendering it useless.

Then, to top it all off the wire attached to the battery case fell off (was soldered on really poorly).

In summery. DO NOT BUY ONE!

Sorry to be the bearer of bad news, i know they are cheap, but that is for a good reason. ‘Buy Cheap, Buy Twice’

And I’ve had to do exactly that.

On the good side, i did get a refund (apart from shipping, so i lost £20!).


If your looking for a DOF adapter in the same price bracket may i recommend jag35.com.

They offer a range of DOF adapters to suit price ranges. 

Mine is in the post as we speak. I can give you a review once i receive it if you wish.

Cheers

A trial of film noir – Lucid Dream Motif

It’s pretty obvious that getting lighting right is really important in photography and Film.
In the last 2 years (prior to that i was kinda floating through a land of photographic discovery) I’ve really come to appreciate every technical aspect of photography – This has lead me onto become interested in manipulating light.
The difference in colour tones you achieve by using different temp lights (6500K ‘Daylight’ being the best imo), Difference in contrast, shadow and harshness by using diffuse lighting (softbox’s, overcast days) the different levels of compression and DOF you can achieve by using large or small apertures.
I wont go on forever, you get the idea. This has lead me to an interest in Film Noir.
Its hard and precise lighting, with the use of extreme camera angles and clever shot composition.
Its got me all excited, so i wanted to have a little experiment.
Next on the shopping list of a set of 3 Studio Lights with Softbox’s (Key, Fill and Back Light).

>LCD Monitor Initial Thoughts

>It was PAINFUL trying to acquire this item! 

The unfortunate thing being; nobody in the UK seems to do items like the LCD4VIDEO external monitor, so without any options i had to order it from the US.
I don’t have a problem with ordering outside the UK, in fact a lot of my purchases are made online to websites all over the world. Main reason being the items i need are not available in the UK.
First of all, Parcel Force are Rubbish. And Second of all, I hate Customs TAX.
For one, my items arrived at the Bournemouth Depot of Parcel force but couldnt be released due to Customs Charges (£63!!) but how was i to know this?! 
No letter was sent to me what so ever. So if it wasnt my me growing concerned about my parcle and checking it online via the tracking number i would have never had known where my item was. 
So…after 19 Days since ordering. I finally had my Item.
Shooting with 35mm DOF adapters offers a few challenges indeed. First of all, and most obviously the issue of horizontal and vertical inverted images. 
Using a 35mm DOF adapter without the use of an Achromat lens (to invert the image) means what you will see onscreen will be your shot but upside down and back to front. 
This (obviously) makes it extremely hard to track your subject matter and to properly frame your shot. 
The other issue being, the freedom of creativity the DOF adapter offers can be quite unforgiving when it comes to getting your subject in focus (say goodbye to auto focus). I personally prefer the Focus all my shots manually, it gives faster and better control over your shot. But it can be very challenging when it comes to shots which require you to be quick when it comes to getting your subject in focus. 
The Answer? 
An External Monitor large enough to make it relatively easy to frame and focus your shot which also offers the capability to flip your image Horizontally and Vertically. 
LCD4VIDEO’s product does exactly that.
The monitor comes with an array of accessories (i opted for the full kit)  from a screen protector and carrying bag to a battery pack to use in the field and a hot shoe clamp to mount it atop your camera.
…Talking about the hot shoe clamp. This I’ve found to be the only let down so far, it don’t feel safe mounting my monitor on it at all. It is clumsy and poorly made, the monitor wobbles and flops about.
Apart from that it is a very good product indeed. The colours are fairly close to what your shooting, its resolution isn’t fantastic but it will do the job when it comes to focusing your shot and the build quality is surprisingly good in contrast to its price tag.
I was, in all honesty expecting a cheap, creaky plastic frame around a low res screen; on the contrary it feels solid and well put together. 
It has a screw mount on the bottom and a slide in mount on the back giving the user a few options as how they want to mount their screen. 
You can change everything you would expect from a monitor (contrast, Brightness Colour) It auto detects PAL or NTSC and you have the option between the two common aspect ration’s 16:9 and 4:3. 
The sunvisor (or sun protector) seems well made and offers good shade for your screen.
There is plenty more to say, but I’ll hold first until its field tested. 
Full review then!
Until I’ve done that, i would recommend it for enthusiasts like myself using DOF adapters.

>35MM adapters for idiots, just like me.

>Right, continuing from where i was. 

I’m not going to babble about DOF too much. And please don’t get me wrong; having a SHALLOW DOF does not make your film look instantly fucking awesome. Of course, I’m not that naive.
Shallow depths of field can be used to great effect, specially in stack focus shots or for drawing the audiences attention to a specific subject.  Also creating Bloom (over exposure seeping light into under exposed parts of the frame) can give a very powerful image.
Enough crap talk.
Now. Back to my Prototype, please remember this is a very early one and in fact cost me around £4 to make myself.
As you can see from the video there is a HUGE amount of noise, and not only from the grain on the GG (Ground Glass, will go on about that later). Also fingerprints, Dirt (i couldn’t remove even with plenty of cleaning)
This is all down to the GG i decided to use. As i was building this prototype on a a budget i decided to test it out with an old GG i had in an old NIKON FE film camera i had lying around (from about 1970′s i think, its lovely and will return it to its former glory one day).
Oh yes, and you have to ignore the focusing section slap bang in the middle of the frame. Its brilliant for manual focusing of film cameras. But not so good when using it for unintended purposes.
Noise?
Well the noise is obviously a big problem. in short, in order to get rid of noise from the GG (specially for HD cameras as they pick up a lot more detail) the camera needs to be shooting at a slow shutter speed (24p upto 50fps preferably…..or if you really want to be pedantic - 23.976 fps) and the GG needs to be moving.
The most popular method of doing this is to make it vibrate. Using a ‘pancake motor’ attached to  a GG holder. 
This then blurs the grain (noise) of the GG and offers a much cleaner image.
(NB it also gives a slight sense of the frame moving, giving a feeling of being shot onto real film)
Simple eh?
Not really. but i wont go into that yet, that is the next step.
That’s enough bullshit for now. 
Here’s the viddie

DIY 35mm Prototype from James Williams on Vimeo.

The main point here is
1. It works
2. It has a shallow DOF (also helped by use of the 70-300mm Lens)
