I have an AD200 and a V850II and I also have a limited budget. Since they are not super powerful and I don't like to depend on the golden hour, I am considering buying a variable ND filter. I also need to preserve the life of the flashes. Excellent video. Thanks for sharing.

Hi Rob, I noticed you took great care selecting your shutter speeds to get the correct ambient light exposure, but on every shot TTL over ruled it and generally reduced the shutter speed. It would have been interesting to see how the pic would have turned out if you had shot in manual to maintain the settings you selected....
@RobTrek4 жыл бұрын
You are correct. My intent with watching the shutter speed was to make sure I stayed within the limits of the camera's (and nd filter) ability to get the desired ambient light exposure. Until the shutter speed indicator stops blinking, I don't really know how many stops away I am. So in much brighter scenes, I'll know my settings will work even after ttl kicks in. Certainly, manual mode is the way to go for consistent ambient light exposure but I wanted to simplify the process by working with just exposure comp once we got within the limits of shutter speed. That said, I should do another video explaining this in more detail and use manual mode with ttl instead. Thanks.

Very informative video Rob. I assume if you have a 3 stop (0.9) ND filter, this may also work instead of a variable filter? Can this technique also apply to more dynamic portraits eg wedding photography?

Thanks for sharing. Excellent video and I enjoyed it. I don't need expensive equipment to do outdoor flash. May I ask what is the size of filter step ring for the lens 45mm 1.8 MSC dia:37mm, so that I can buy the Variable ND filter that goes with it. Thanks
@RobTrek3 жыл бұрын
Thanks. I bought a 62mm threaded filter and a step ring kit together. So it takes 5 step rings to go from 37 to 62mm. I bought the 62mm so it would fit my largest lens. However you can buy a smaller ND filter to fit the 37mm ring size. Here are the exact parts: Step Ring kit: amzn.to/2OAGa1Q ND Filter 62mm: amzn.to/2OAGa1Q ND Filter 37mm: amzn.to/3vCMh66 Note: These are my Amazon affiliate links and I'll earn a small fee for qualitied purchases.

@@RobTrek, Thank you very much for your response and help. Is vignette around the corner the reason you bought 62mm step up ring? I see it happened sometimes with my wide lens like 7-14mm lens. Olympus EM1m3 has internal ND6-ND32 should we use in this case? Thank you
@RobTrek3 жыл бұрын
@@phanxquang I bought the 62mm so I could fit my larger lenses and step down for smaller lenses. If I bought a smaller ND, then it would vignette if I step it up back to 62mm. So best to buy the largest size you reasonably need. For example, I do have larger lenses but will never use the ND on them. Vignetting can happen on wide angle lenses and sometimes can't be avoided. Sometimes the step rings themselves can be causing the vignette. Also, the IBIS moves the sensor making the possibility of vignetting even greater. If this happens to you, be sure to frame the scene so you can crop out the vignette in post processing later and turn off IBIS.

Another great video Rob!. I'm not sure why in the last section the 1/180th shutter was blinking as it is slower than the 1/250th limit for even a normal flash. Is it because the Godox in TTL mode had reached its maximum power?
@RobTrek5 жыл бұрын
I believe the sync speed is set by the trigger, telling the camera that it can't go any faster. Probably has to do with the wireless transmission delay. This does not affect high speed sync, as once the flash receives the signal, it fires in hss without the need for another signal.

Hi Rob Thank you for another excellent video. On your light stand, why do you have the extra bracket to hold the flash instead of just using the cold shoe that comes with the stand? Is that to align the flash more on axis with the umbrella? Thanks
@RobTrek5 жыл бұрын
I prefer the "S-Mount" as it takes the tension off the fragile hotshoe on the flash. It also has a bowens mount so I can quickly swap out with any other modifier such as a soft box.

Hi Rob, Could you please explain what are the limitation of your camera when it comes to sync speeds? I thought we can use pretty much any shutter speed above the sync speed of the camera when we use HSS. But it seems not to be the case.
@RobTrek4 жыл бұрын
Hi. You can use any shutter speed in hss mode. It's only limited by the cameras fastest mechanical shutter speed. On the EM10ii, it's 1/4000th. The EM1ii is 1/8000th.

Does ND filter has any impact on aperture? Like I got to know that polarizer filter decreases the aperture by one stop.
@RobTrek4 жыл бұрын
ND Filters reduce light similar to polarizers. They are indexed with terms like ND2 to ND32. The number represents how much light is reduced. ND2 means 1/2 the light. 32 means 1/32 the light. To convert to stops of light, take the square root of the denominator(approximately).
