CREATING LIGHT LEAKS 'IN CAMERA'

If you've been following this blog or if you watched any of our movies, you'll know that we love to try and do things as practically as possible. We try and capture as much as we can in camera, from colour to practical effects. In the age of 'Fix it in post' I have to say that I've always felt more comfortable getting as close as I can to the final product on set than I do trying to get the same effect in post production. Thats just me and how 'I' do things though. 

Ungraded shot from Hollower (2014).

I get it, digital effects and post production does a lot of good, I do use a whole heap of things from Colour correction to Masking to CG and I'm a big promoter of visual effects and post work, if it is needed,  just not if its done for the sake of it. I've saved many shots and even whole scenes in post, because something just didn't work on the day, but surely the goal is to get it right at 'showtime', or as close as you can. My 'opinion', and thats all it is, on digital effects and heavy post production is that its a great tool to help you when all else fails. You're main goal should be that all does not fail.

I started shooting my fourth feature at the end of 2014, the film, Hollower, is the story of anagoraphobic who can't leave his studio apartment. In the film there was a scene in which he attempts to leave his 'fortress of solitude' only to find that his condition won't allow it. My first thought was how I would present this visually, and I immediately jumped to what digital effects I could add in post production to represent the severity of his illness, immediately light leaks and an adding various blurs and distortions sprung to mind. I stopped myself there and just took a step back and remembered my 'Don't fix it on post' rule. How could I do what I wanted to do 'In Camera'? 

Then I realised I had the answer.

LENS WHACKING

Lens Whacking is an old school and pretty well documented photographic technique, that involves creating light leaking directly onto the cameras sensor rather than being filtered solely through the lens. The technique also adds some very interesting blurs and distortion due to the way that the lens is held in front of the camera. In terms of the effect I was looking for in the film 'Lens Whacking' was clea the way to go.

Interchangeable Lens System Camera (Canon 600d/T3i)

First of all, your camera will need to have an interchangeable lens system, this is much more common these days with the advent of DSLR'S and Mirrorless system becoming a pretty standard part of the No/Low Budget filmmakers arsenal.

Remove lens from Camera.

The effect comes from removing the lens and setting your cameras 'Operate without lens attached' to on (It called something different depending on the camera model, but its a pretty universal feature and on the Canon it just involves hitting the Video button without a lens attached) this allows your camera to shoot without having your lens attached (Obviously). 

The option looks different on the Panasonic G7.

Now you have pure, unfiltered light hitting your sensor.  You can now simply hold your lens up to the sensor, but instead of attaching it, you allow light to slip in through the gap between the contacts. Moving it around until you have the desired effect. 

Hold the lens over the sensor without connecting it. 

I've found that the effect works best with Normal or Longer focal lengths and shooting on a Canon 600d (T3i), I got the best results from using the 50mm 1.8 as the shorter focal lengths seemed to give less desirable results. It takes a little experimenting to get it right, but the results can be something fantastic.

THE PINSTRIPE PIGEON BAND

A few months after shooting Hollower, I was hired to shoot a video for The Pinstripe Pigeon Band to go with their new track 'Never Be Apart'. The song was a slow ballad and the band wanted something that had a restless, dreamlike feel to go with the song. I immediately thought of 'Lens Whacking' as a way to achieve the look the band wanted. I explained my approach and they loved the idea and so thats what we did, I also shot at high frame rate and played the song a double speed (So that it matched when conformed back to 25fps) to help sell the dreamlike visuals that they were going for and I was very pleased with the results.

Still from 'Never Be Apart' The Pinstripe Pigeon Band

I did hit a snag however. After we shot the story elements using the technique, we arrived on location to shoot the bands 'performance' element. Because we were based about 4 hours away  and the video had come together in relatively short notice, we hadn't seen the location outside of photographs and it was actually much smaller than we thought it would be. This was fine for close ups, but the wide shot was a vfx shot and had to be locked off, this meant that I couldn't take the lens off for the shot and so it suddenly stuck out like a sore thumb compared to the rest of the video. 

This was the one place I knew I would have to 'fix it in post' and add my leaks after. It came out ok, saved by some time in the edit fixing the problem, but it really did hit home just how much difference doing something practically actually makes. It also serves a good example of both approaches. You can check out the full video for 'Never Be Apart' below. 

So overall my point is that you should rely on post to save your ass, doing things after the fact is great, but giving a little bit of forethought to how you want your final piece to look can really, doing as much as you can there physically on set can bring your stuff to life, Plus its a lot more fun :)

COLOUR GRADING IN CAMERA

Last week I talked about the advantages of getting your image how you want it 'in camera', this saves me a lot of post production work, especially when it comes to grading. A lot of projects I work on have to have a fast turn around and I know that a good deal of that will be grading the footage right at the end to give it its final look and bring out the colours and depth that the production needs.

Raw Camera Image (Ungraded/Corrected) Slasher House 2

As a general rule, I try to get my image as close to the final product and the truth is, these days, I do very little colour correction after the fact as well. There are a lot of reasons for this, but mainly because its the that I personally like to work. As usual, Its not the right way or the wrong way, just my way.

As chance would have it a friend of ours, Georgie Smibert (Who played Deputy Howells in our latest feature film 'Cleaver : Killer Clown' and our Short 'Slaypril Fools Day 5' ) needed to shoot an audition for a film role she was applying for. As recompense to our actors giving up their time to work on our stuff we're always happy to help with showreel and audition stuff  (A good habit for No budget filmmakers to get into) and she wanted to shoot the audition as a 'scene'.

We made the choice to shoot the scene as if we would shoot it on a set, but just from her angle, as if it were just that take from the overall coverage, this was mainly so the other actors didn't distract from her performance.

Now Georgie was going to cut it herself on a basic windows editor (Movie Maker I think) and so therefore I knew she wouldn't have access to correction tools or anything like that. So we decided that we would get the footage that she needed ready to go straight from camera, but it also gave me a chance to take some reference pictures in terms of how I approach colour grading.

I do my colour grading and correction 'in camera', before I even start shooting, I hate to rely on post for 'anything' and as such I approach shooting in a very practical way, so that, for the most part, I'm just making cuts and not spending weeks on trying to get colours, tones, grades right. I think about it at the time (or usually months before hand) and then make sure I get the desired image there and then.

Original 'Flat' set up for room to Grade/Colour Correct

The camera I use currently is the Panasonic G7, which give me unbelievable control over everything from Curves, to Contrast to Saturation to Colour Temperature and beyond. All things that I would tweak in post otherwise I can now just do in the camera itself. I used to a lot of this on the Canon 600d too, although that gave me a little less control overall, its still had an unbelievable amount of control via its picture profiles and my last 3 features were shot on it, I had to do very little in way of correction or grading in post even on Canon's Rebel series. I'm fairly new to the G7, but so far it makes controlling my image input a breeze.

'In Camera' Colour Correction

To me the change is very noticeable and a much nicer image. I added a 'hair light' at the rear just to bring out Georgie a little more. But that was a cool LED with no gels or filters or anything, all the colour came and depth came from just working with the cameras Profile settings to get the desired level of Contrast and Saturation and of course Colour temperature and White Balance. I also enhanced the sharpness a little too, but thats really just lends a hand with focus and as we weren't doing any post at all this would really be my only chance to fix that.

The biggest thing I've found is the use of white balance and how it drastically effects the tone of the image, I was always advised to balance to white of existing light in the room, but really experimenting with the colour balance opens up a world of style right in your camera. I may do a colour chart to demonstrate how balancing to different colours effects the image, if you want something like this, let me know in the comments below, I tried finding one online, but so far, no luck.

Anyway back to Georgie's Audition, the scene in question was quite light and fairly comedic, So I went for a brighter, lighter colour to keep the tone light, pushing the cameras colour temperature toward a warmer Orange tone. If I were doing a Horror or a Sci-Fi or a Thriller I would make a drastically different choice in terms of what colours I would balance to. This is how I apply a grade 'in camera'. 

Now, obviously this approach gives you less control in Post, but for me that is the intention. It forces me think about the decisions I make and, of course, it forces me to be a little more prepared. Now balancing to different colours can give your image a completely different feel. I'll make these choices fairly early on in larger productions and do tests with lights/gels etc to get the look that I'm after. 

Adam Dillon (Nathan from Slasher House) dropped in on his way to the Premiere of our other new feature Hollower last weekend and I stole a moment from him to demonstrate the approach and the drastic difference it can make. I had my camera set for a a few different looks I'd been working on.

So this what the original 'Normal' image looks like. Set for the the rooms natural White Balance. A fairly standard shot. To grade it i would probably pull the curves out to make the shot a little more 'Flat', like in the first example (The G7 isn't really the best for shooting flat images, so you work with what you've got) but this is pretty close to how I would shoot, if I were preparing to do colour work in post. As you can see its a fairly bland image in terms of colour. Below I've worked on some quick picture profiles, just to show how much of difference shifting colour can change the tone and style of an image. 

Obviously its a fairly quick example. On set I'd take much more time in lighting my subject and  surroundings first, but for the sake of a quick reference of what I'm talking about, this should demonstrate it fine.

All of these images are raw JPEG frames from the camera (The Panasonic G7 allows you to save stills straight from the footage in camera), uploaded straight from the card. As you can see each Grade changes the mood of the image dramatically, each one of these grades was created 'in camera' by adjusting the cameras visual settings. I used a cool LED to give me a little back light, but that was it. My camera only stores 4 looks, but really the looks you can create using just your camera are almost infinite. This is before I've even started to bring other colours into the mix using gels/filters etc.

I understand some people just won't understand my approach, its extremely counter intuitive to the way most people have become used to working, you just have to look at a modern standard film workflow and how big a part 'grading' and 'colour correction' play in that to know why this approach won't suit everyone. It 'sometimes' doesn't suit what I'm doing either, as I talked about last week. If I can though, this is my preferred way to work, to me I see it like painting on set and its a lot of fun. 

This is just one of the many ways I work, and it suites me, it might not suit you, but for me filmmaking has always been about thinking outside the box and trying things that are new to me.
