The Magic Cloth Technique

    The magic cloth technique refers to the dodging and burning of a digital sensor during a long exposure… Pre-camera editing!!

It’s all about the Highlights

No! It’s all about the shadows

The magic cloth technique was born out of the need to get the image right in the camera but to still increase the dynamic range of a scene. Under normal circumstances, the top part of a landscape is brighter than the lower half. Even with a mirror lake the difference can be a couple of stops. In order to get the best exposure of both the land and the sky, photographers have traditionally used filters which are darker at the top and clear at the bottom. These are called Graduated Filters (grad) and although they come in different colours, the most popular are Neutral Density (ND – Grad). Neutral density adds no colour to the scene. Aside from different colours, Grad filters come in different strengths – measures in stops. They also come as soft or hard grads. The Magic Cloth technique has a similar effect to a soft grad filter.

The Magic Cloth Technique involves controlling the amount of exposure to different parts of a scene during a long exposure. To acheive a long exposure, shoot at night or use a dark filter – ND Filter.

 

ND (Neutral Density) Filters

So if you wanted to have graduated filters to cover every eventuality, you would have a set of around 8 filters plus a holder and adapter. If you want the quality versions, you are talking about the same price as a used car. This was my obstacle, I couldn’t afford them! But while I was looking I decide to buy a decent ND filter. This allows me to get a long exposure in daylight.

Magic Cloth is a technique of dodging and burning the digital sensor.


The ND filter is just to lengthen the exposure. You can get silky waterfalls or nice wave action without having to wait for it to get dark. Like Grads, they come in different strengths. I bought an 6 stop ND (x64).

Magic Cloth
This technique seems so obvious to me now! It is as simple a using a cloth, sock, wallet, hat or whatever you like to allow different parts of a scene to have different exposure lengths. The basic technique is to fire the shutter while covering the front of the lens with the cloth and slowly raise the cloth to reveal more of the scene. The more slowly you raise the cloth, the higher the strength of the Grad. For example; if you expose the foreground for 30 seconds and raise the cloth very slowly to allow only 3 second on the sky, you will have a 10:1 ratio which is just over 3 stops. The more you move the cloth, the softer the grad.

Use your camera light meter and set the exposure compensation about 2 stops over. This should give you a really nice exposure on the immediate foreground.

Landmannalauga

The magic cloth technique isn’t for everyone or for every scene, but it is certainly cheaper than carrying around a set of expensive glass filters. It is probably best thought of as being a night photography technique, which I have adapted for day photography with the use of a strong ND filter.

The downside is that you need a long exposure for this to work. The longer the exposure, the more control you will have. For day-time shots, you will need a way of slowing your exposure use a combination of ND filter, small aperture f/16 – f/22, and slow iso 50-100. I have had acceptable results with 2 second exposures. The other downside is that is can involve a lot of trial and error, this can be frustrating if you are taking a very long exposure. It is not really suitable for extremely long exposures as your arms and shoulders will ache.

The upside is that is is a very cheap method and can give excellent results. Also it is dynamic, you can expose all the sky in one go to give detail to the clouds, or you can use short bursts to give the clouds extra movement. It is possible to change the exposure if the sky suddenly changes. It is possible to use a mixture of angles if one side of a scene is too bright. It is also possible to clean your lens half way through an exposure. Very useful for waterfall shots.

Skógafoss

This shot of Skógafoss would have been very difficult because the spray was constantly soaking the lens. I was able to use the cloth to keep it dry during the exposure.


Most students of the Magic Cloth Technique found the concept easier to understand after watching these videos:

Reyðarfjörður

This was an extreme condition as the sky was a lot brighter than the cliffs. I gave the foreground around 10 minutes and the sky around 10 seconds in total. I exposed the sky for about 1 second every minute to give the clouds a sense of movement.

  1. Tony hi. so I understand that u have to take several exposers of the same landscape in order to get the effect u want right?thx iris

  2. Hi Iris
    it really depends how good you are with the technique. If you have a simple scene and you calculate it correctly there is no reason why you wouldn’t get it right first time.

  3. Hi Tony,
    This is a great idea! So I guess what you do is to meter for the sky and then the foreground, set the cameras exposure settings for the foreground and keep the sky part covered, only exposing the sky for the metered sky reading.

    Can I ask why not use hdr tecniques for high dynamic scenes?

    I willl certainly try your method.

  4. Excellent – and as you say, once you think of it, the technique is so obvious! Must give it a try sometime. Congrats on POTW on ePz BTW
    Andy

  5. Hi Trevor, you certainly could meter for both sky and foreground. What I tend to do is use average meter and over expose by two stops. I experiment from there, but it usually takes just a few goes before I start getting the right result.

    HDR… I found that it was difficult to achieve an image that looked like a photograph.

  6. Thanks Andy
    The image can be seen on EPZ… one of the best photo websites out there:
    http://www.ephotozine.com

  7. I had read about something like this in connection with shooting fire-works, in order to collect a bunch of them in the same shot. The lens would be disclosed only when they’re firing, keeping the exposure on bulb setting.
    I also knew you can use a cloth to cover a light intrussion into a long exposure… BUT this thing that you explain here had never come to my mind, and I don’t recall reading about it before! Well, THANK YOU very much – this will be put to the test !! :)

  8. Just back from Iceland, where is Church mountain which I have seen in the title of some of your shots. Regarding grads, which I use, you don’t need that many. Soft grads are no use on 35mm or your Canon 5D and certainly no use on DX size digitals. The gradation is larger that the sensor size and are basically for large format cameras. I use just 2 grads, often in combination, and you can see the effect before you take the photo. Having said that, I certainly very much admire your results without spending money. Well done. Back hopefully for more aurora in Jan 2011. Ken

  9. Thanks Ken, I appreciate your comments!

    Church mountain is near to Grundarfjörður. The mountain is called Kirkjufell in Icelandic.

    I am not sure what you mean about the graduated part of a soft rad being larger than the sensor… surely you are supposed to put it at the other end of your lens?

  10. Hi Tony,

    Thank you for sharing this fantastic technique.
    I had a go at it about 2 weeks ago as the night was falling and I’m quite happy about the results for a first time. I wrote post on my blog about the experience.
    Looking forward to improving!
    Your pics are incredible.

    Cheers,
    Olivier.

  11. Thanks for sharing this really simple technique. One I’ll definitely be trying when I get a chance. Really like your shots in the article, very good work.

  12. Hi Tony,

    In Taiwan, they call it the Black-Card Technique since people would use a non-reflective black card or cloth to shake it up and down in front of the lens to control the amount of light. :D

  13. Hi tony… though got all the necessary GND filters, but sometimes the dynamic range of the light are too much for the filters to balance… what i did before was take 2 exposure shots and blend it in CS… but after reading this tutorial, i believe this would work better because it’s more gradual… my only concern is would there be any traces of the clothes movement? do i need to use any particular cloth color? thanks…

  14. Hi Bill
    yes this is true and I am not sure if the ‘Black card technique’ is a night or day technique, but the principle is the same.

  15. This technique can be used in conjunction with GNDs. I find a dark coloured cloth is the safest.

  16. Sorry Tony only just got round to reading your reply. What I meant that putting a soft grad on the front of the lens, say using a Lee filter holder, it is impossible to position the filter so that you are using at least some o the clear part as well as the darkest part. You can easily do this on a 5X4 large format but not on 35mm or smaller sensors as the graduation from dark to clear is actually bigger than the sensor. Hard grads seem to be the only one that will work. I do have both versions because I did use 5×4 but the soft do not work full on my D3. Looking forward to Jan for aurora but the latest forecast from space weather is not looking good. I did manage to get one in Sept from Myvatn. Really enjoy looking at your works of art. With results like that who needs grads! Ken

  17. Hello!

    This seems very exciting and interesting.
    But I have some questions about the technique.

    Is it correct that you are using that ND-filter as a “cloth”? But what if the landscape is irregular – let’s say with a dark mountain that peaks up into the sky. How do you deal with that, because you don’t want to cover that part?

    I found really cheap ND-filters on the web ($4) but I guess you are using higher quality filters. What brand are you using?

  18. Hello Paul.
    No, I am not using the cloth as an ND filter. I am using the cloth with an ND filter. Think of this as a night photography technique which you adapt to daytime with a dark (ND) filter.

    Mountain peaks are a problem for this method and for regular NDG (grads) filters. More movement in the cloth will give you a softer graduation. Shoot in RAW and use lightroom to bring out some of the shadow detail.

    I use a very slim B&W filter. and I stick a very slim Sigma polariser on the front.

  19. Hi Tony,

    Very interesting technique. I have two questions though : Do you move the cloth constantly ? do you put the cloth right in front of the lens or in a small distance to allow less hard edge effect ?

    thanks.

    Seb

  20. Interesting question, Seb. I do move the cloth constantly to give a more even effect and I hold the cloth right up against the lens. Some people think I am polishing my polariser. I do this to limit any stray light that might enter the lens. Any hard edge effect is eliminated by the constant moving of the cloth.

  21. Tony, this is such a great trick that has obviously been very effective for you. I have been doing long expsoure photography (particularly light painting) for a little over a year now and feel that this technique could be utilized quite often. Time to find some dark cloths and put them in the gear bag. =)
    Thanks!

  22. hi Tony
    incredible technic with this “Magic cloth” , i never imagine it, i will try it soon to test it
    thanks to share

    regards
    Yan

  23. Thanks for the article Tony, but I have one question do you use Circular filters or the square ones?
    Best regards Sigurbjörn Árnason

  24. Hi Siggi
    I use a circular ND8

  25. Thanks for the idea! I had this in mind ages ago but I’ve never really gotten around to actually try it. In the meantime I missed some great opportunities to use this technique and tried HDRs instead. But the HDR programmes give very unsatisfying results and images that don’t look real at all.

  26. wonderful! i can’t wait to try it out. thank you for sharing your techniques and tips! your photos are fantastic; i enjoy them on flickr too.

  27. Hi there

    I’m interest by this technique as I am a user of ND Grads.

    Do you cover the whole lens and move the cloth up slowly? Just the sky?

    Can you give more detail on it? Better still, could you create a video?

  28. Hi Jools
    it really depends on the conditions and what I am trying to achieve. Generally I allow exposure to the whole lens for a few seconds, then cover the whole lens and slowly reveal the foreground. A video would be a great idea.

  29. Thanks for tha Tony.

    Curiosity, how are you metering for your exposures? I presume that you are doing your work before sunset otherwise it becomes guesswork.

  30. Tony. Ignore that last comment. I figured it out:)

    Just seen a nice sunset out of the appartment window and got it first time.

    It would have been a VERY long shutter speed but I’d left it on 6400ISO at roughly 30 seconds.

    Having done this a couple of times, I understand why you overexposure the foreground but a stop or two.

    Cool stuff, and I’ll be trying it out on Britain’s coast this coming April.

  31. Great technique , I was set aback by the quality of your pictures , amazing work !!! , I had a thought reading all these comments and all your replies , maybe you should video tape how you do it and post that for all of us thick headed types to see … Cheers.

    I have to figure out how to get to Iceland now !

    Dan

  32. Hello Tony.
    Thanks for sharing your great photos.
    But I’m not really understand the technique.
    Is it like the method as the following?(about 2min30sec)
    http://www.youtube.com/watch?v=kMGgCuTqloo
    Thank you!

  33. yes, it very much like the black card technique but using a cloth is more flexible, in advanced techniques you can make different shapes during the exposure. The difference is like that between cutting and sculpting.

  34. OK, cool! Magic cloth is more widely use. but should I shake the cloth while it makes the different exposure? Or just move away the cloth?

  35. Hi Luo
    only you can make that decision. Different scenes need different styles of cloth movement.

  36. WOW Tony, these are really amazing photos on your website. It just goes to show that i have a long way to go still.

  37. Great images you have on your webpage!

  38. Dear Tony, do you mind to
    share the efix to each photo so we can guess the setting. Thx b4

  39. You mean the EXIF so you don’t have to guess? Sure, you can see EXIF on all my recent Flickr uploads.

  40. Holy smoke Tony ! This is incredible ! I’m going to have to try this. Are you planning to get a YouTube instruction video of this technique ??? Great work !!!

  41. Tony thanks for sharing your magic cloth techique on the web. I have played with the techique a few times now. I think I finally got a good example at the Bass Harbor Lighthouse in Bass Harbor, Maine USA this summer. One of the shots (not the best) can be seen on my shutterpoint account and on my flickr account. Your images are among the best I have seen on the web and keep me trying to improve my skills.

  42. Many thanks for writing Dale, I will check out your images!

  43. This unique blog post, “Tony’s Magic Cloth Technique

  44. Hi Tony,
    great technique and great photos,but I have a question,
    to use this usefull technique the shot must last more than a second obviously..
    if I’m shooting in daylight how can I solve sky exposure?

    p.s.
    sorry for my english I’m italian

  45. Hi Matteo,
    to do this during the day use a dark filter – ND (Neutral Density)

  46. Hi Tony, this technique is pure brilliance! I was just debating on whether to buy some ND grad filters but this method seems to be a lot more flexible and better value for money. Coupled with the fact that I can use bracketing, layers and masks to also produce a grad ND digitally, I see little reason to buy them. Time to play with some black cloth! Thanks!

  47. great idea. I often use a ND grad filter hand held in a similar way over a ten stop. I can’t remember the American photographers name who did something similar in the late 1800′s.He invented a gismo like a profile gauge (for wooden moldings) that he put inside his big box full format camera. He moved the teeth of the gauge to match the mountain profiles. Opened the lense and then flicked up the profile gauge to expose the sky at the last minute. Loving your work Tony. I will be in Iceland in September and hope to get images half as good as yours!!!

  48. Hi Tony!
    Is it possible to use this technique of the magic cloth with round lens like my nikon 14-24? there are NO filters for my lens, this is amazing lens but I can never use polarizers, nd grad filters or anything. Would it still work for photographing the sky or winter landscapes in iceland with the technique of the magic cloth?
    tks

  49. Thanks for your comments everyone!
    Ana, it is possible, but you have to wait for it to get dark ;)

    The 14-124 is a problem concerning filters. Lee have invented a filter holder, but this is a huge devise and a lot of bother. If I had this lens, I would get a professional glass cutter to cut an ND filter to fit in the back between the lens and body. Not even sure if this is possible though?

  50. Hi Tony,

    Thanks for a great workshop this past February. You have inspired me to get to the next level in my own photography. Your Magic Cloth technique has proven useful already…I got a few puzzled looks when I started moving my hand in front of my lens during one shoot! :-)

    –John

  51. Thanks for your kind words John. One morning on the beach at Jökulsarlon, there were so many photographers using the Magic Cloths, that one guy started waving his hand in front of his lens because he felt left out. It’s a great story because it’s true!!
