However, itвЂ™s probably only about 1/4 stop difference, maybe 1/2 stop is things are really red. The only slightly practical application I can really think of for this fact is that if youвЂ™re working in warm light, diffraction will set in slightly sooner then normal. However, I thought it would make an interesting side note, so IвЂ™m including it here. For photography, I generally like to think of an вЂњaverageвЂќ вЂ“ since I donвЂ™t think IвЂ™ve ever personally photographed just one particular wavelength!ДЇrom an вЂњin the fieldвЂќ perspective it really makes little to no difference if one color is diffracting 1/4 stop sooner than another, so it was excluded from the video to keep things from getting too confusing.

So, red light diffracts slightly sooner than green which diffracts slightly sooner than blue. Technical note вЂ“ One thing that is often brought up in discussions about diffraction that I (deliberately) left out of the video is the fact that light actually diffracts at slightly different apertures depending on its color (wavelength). Captured with a Nikon D3x, Nikon 14-24mm at 14mm, F11. It wasnвЂ™t until F/11 that I had acceptable sharpness throughout the image. Why? The rocky area you see in the foreground was MUCH closer than it appears in the photo (less than a foot if I recall). In this case, I ended up at F/11 with a 14mm focal length. While that is normally very true, in some cases you still have to stop down a bit. In many cases, when people think of wide angle lenses, theyвЂ™re under the impression that you never really need to stop down beyond F/5.6 or F/8 due to the massive depth of field. Captured with a Nikon d800e, Zeiss 21mm, F/11. Although an aperture of F/8 would have been slightly sharper, the added depth of field I achieved by shooting F/11 allowed me to keep everything acceptably sharp from foreground to background. In this case, I had to dig into diffraction a little with my D800e. Captured with a D810 and Nikon 24-70mm at 45mm. In this case, the starburst was more important to me than a little diffraction. Sure, F/11 would have been a touch sharper, but the truth is IвЂ™d be completely comfortable printing this at 36Г—24 after a little sharpening. However, I also wanted to capture a good starburst and the smaller F/19 choice gave me just that. In this image, I could have easily used F/11 and enjoyed perfectly acceptable depth of field. Captured with a Nikon D800e, Nikon 28mm 1.8g, F/8. This rendered an amazingly detailed image. That lens is crazy sharp at that F/stop and I didnвЂ™t have to worry about diffraction. Captured with a D810, Nikon 28mm 1.8G, F/9.5.ДЇor this image, depth of field wasnвЂ™t much of a concern, so I selected F/8 on my 28mm 1.8G lens. I feel like I can print this about as large as IвЂ™d ever like. While my D810 is seeing slight diffraction at F/9.5, it made little difference вЂ“ and was essentially gone with just a very slight amount of sharpening. So, F/9.5 and a little hyperfocal distance saved the day. I had experimented with F/6.7 and then F/8, but the truth is those F/stops just werenвЂ™t getting me the foreground to background sharpness I needed. So, if youвЂ™re ready to discover the truth about diffraction and its impact on your photography, go ahead and press that play button:ДЇor this image, I only needed F/9.5 to pull it off. WhatвЂ™s the difference between sharpness and depth of field?.What causes diffraction in the first place?.Does diffraction limit the usefulness of high res sensors?.The video uses example after example to tackle burning questions such as: WeвЂ™ll dive into just what diffraction is, what it looks like, and what causes it.ДЄnd, most importantly, weвЂ™ll look at how diffraction can impact your photography and what you can do about it.

In this video, weвЂ™ll go over all the essentials you need to know about diffraction in photography and kick the myths to the curb. The problem is, those discussions can leave you more confused than a chameleon in a bowl of Skittles.
