I don't bother. All my photos are taken in known locations, and photos saved to albums with a description of the event, so I know where the photos were taken. I could see it being useful for wildlife/landscape photographers that are hiking through the middle of nowhere that want a record of the location for future trips.

Just got the dreaded news that they cancelled the races tomorrow all together due to the storms risk. All the feedback is still very much appreciated, but now I'll have to figure out something else to do with the lens while I have it. Maybe see if I can find some good lightning of update family portraits or something.

I have insurance on my personal gear and on the rental. Unless you know of an insurance plan that can replace damaged equipment right there on the spot, it'll be useless to keep shooting at a time limited event.

I rented the 16-50mm f2.8 PLM and it arrived yesterday. They included one B+W nano costed clear filter as part of the deal, so I just bought a single Platinum (Best Buy store brand) multi-coated UV filter as backup. When playing around with them last night, both seemed to do ok with image quality, but both introduced a noticeable lens flare when a light source was just out of frame unless I was zoomed in about 28mm or more. So all in all they are about equal. During the day shouldn't be much of an issue, but would be a big one when the track lights come on at night. I'll be track side instead of in the line of fire, so they'll come off at that point. I did talk to the track a bit, and they may not allow the shot I was hoping for anyway, but we'll see. The race team is willing to give me a crew shirt to sneak on. Lol Now to hope the rain holds off for us.

And yes, I got the insurance on the lens. :p

And if you don't have a place to set up with a lot of traffic, just grab a little flashlight and make your own trails as you wave it around in front of the camera. If you move yourself around while doing it, you'll disappear in the final image and leave that parrot just as stumped. Welcome to the wonderful world of light painting!

I've not heard about PS increasing dynamic range, but something that hasn't been mentioned is it virtually eliminates image noise. You are getting full RGB values for every single pixel, and a byproduct of combining them is it removes noise. I'll let someone else explain the technical reasons, but sample images demonstrate it well.

I've never heard of that. Do you have any examples of a polarizer used on flames? I tried searching for the topic, but found nothing. The closest I got was its effects on smoke for things like a forest fire.

Calibration issues aside, I do think shooting through the OVF and using the dedicated focus sensor (I think that's phase detect?), the dedicated focus sensor is more sensitive than the on-sensor focussing. So in low light, I would prefer that as long as the calibration is good.

There's several problems with standing further back. There would be a lot of clutter (starting line equipment, staff, pedestrian bridge, etc) that would be in the shot that I don't want. I also don't have enough space behind them to remain safe. Even if I did, I don't have a high enough quality lens for that, and would also get a lot of heat distortion at the needed distance. Here's what I'd be working with, and also the team I'm in talks with. VOLUME WARNING!

The tripod would be in between the two cars, aimed down the track shooting up the tailpipe. During staging, heat would be minimal as the exhaust would be behind the camera and shooting back. I probably get more heat from shots like in my original post when doing the pre-stage flame shows. Only when the tree goes green and they take off would the camera get any direct thrust/heat as they pass.




True, and I would have time to clean. Unlike regular drag races that launch in quick succession, jets have a fair bit of time between runs due to setup time.



There's a shielded divider between the lanes where they stage. You can see it somewhat in the photo, which has the Randy O'keefe sign on it. So the tripod, which I can put low with a very wide stance, would be shielded and the camera barely above the divider wall. The anchors will be another questionable aspect that I won't know about until I get there. I think there will be some posts for the divider I can tie down to and prevent a situation like this.

(alternate view linked in the video description)



I have a wireless remote to trigger it. Ideally I'd just get up there and hand hold it, which would solve all my problems and allow other shots as well, but the track likely wouldn't allow it. I have been in talks with one of the teams to have a photo session they can use for their advertising, so I may try name dropping them to get special permission for this. Doubtful it'll work, but we shall see.

The other advise is appreciated, and much of it things I've already been mulling over. I do think the protective box idea is likely the best option, if not for issues with portability and expense to build it. Having been up close and personal with these beasts, I think it should be ok on an anchored tripod, and perhaps a protective sleeve of some sort for the body.

Why must my hobbies be so difficult??? Lol

Before we get to the heart of my question, let's get any thoughts of debating the idea of a UV filter out of the way. Normally I don't use one, but I potentially have a very specific and extreme use case coming up, and a lens hood will not do a thing to protect it. My plan is to set my camera up between the lanes at a drag strip to catch photos as they launch jet cars. I'll refer you to the photo below to get an idea of what's going to happen. Now imagine a car on either side of the camera in close proximity, both with full afterburners going, blowing anything on the track back behind them. They do sweep the track, but there's always going to be little bits of debris (tire rubber, pebbles, small dogs...) getting blown back at the launch, and my camera would be in the line of fire. The blast would only be for a few seconds at a time, but those few seconds are intense.



So yes, I'm sure I want a UV filter or other solution to protect the lens.

That said, I see quite a wide swing on pricing. Are there going to be major differences in quality and maintaining of image quality? Best Buy has their in house brand multi-coated filter for $35, or a Hoya NXT for $65. I know some other brands get way up there in price. I'm hoping to find something that retains decent image quality that isn't going to break the bank.

*The comment about small dogs was only a joke. :p

If I'm not mistaken, when you apply custom image settings in camera, you have to save them as a new jpeg to get the settings to "stick." The original RAW would be left as is, as the format suggests. It's the digital negative, so it's not supposed to be modified.

The problem with longer exposure times is I've found that to lead to excessive smoke in the shot as well. That's why I do it in post, plus it gives you the flexibility of picking bursts that go well together and moving them around to make a custom multi-burst.

Another thing you could do with a single exposure is set it to bulb mode and get a big piece of cardboard (preferably painted matte black). Hold the cardboard in front of the lens to block the light and open the shutter. When you see a burst you want, lift the cardboard out of the way for a few seconds and then put it back. This acts like a shutter while the sensor keeps recording. Do this for several bursts and you have an easy in camera composite. You'll need to be in a very dark location so ambient light isn't washing things out.

I prefer to make my own composites in post.

On a related note, something else you can try is ditching the tripod and intentionally moving the camera during the exposure for some interesting abstract photos.

Case in point, check out www.translationparty.com You can type out a phrase in English and it'll automatically translate between English and Japanese over and over until the translations reach parity. Sometimes the translations are still relatively understandable. Sometimes they are... Interesting. A good starting phrase is the classic line from Monty Python and the Holy Grail:

"What is the airspeed velocity of an unladen swallow?"
