Beautiful shot of a beautiful baby JDeluis!

Something new my son and I tried last night. I've been wanting to try this for some time and decided I needed to experiment while there was still snow on the ground. So last evening my son and I went out to the hay field behind my house with tripod and goodies and shot these.

now that we know how to do it without setting ourselves on fire we can perfect our technique and work on finding some cool locations to place it. I need a tunnel!

Thank You.

Also :lol: at the bold comment. Great pictures. I thought you were setting up fireworks, then noticed it was someone in the picture lassoing fire.

It's steel wool. As it "burns" it gives off sparks. Really fun to do and no more dangerous than running a grinder on metal.

How do you hold on to the steel wool to be able to spin it in the air? Do you just light the steel wool with a match/cigarette lighter?

Very nice job!

I tied soft 3/8" rope to a carabiner clip and attached it to the end of the whisk (it has a loop on the end so you could hang it up in your kitchen).
Light by touching the terminals of a fresh 9v battery to the steel wool and swing the rope in any pattern you want.
I ran out of SW last night, might do some more interesting shots tonight.

Why do people hide the EXIF date? Some of us would like to learn from other's experience.

Most of the time it isn't about hiding the EXIF. Many different programs strip and/or corrupt the EXIF. Sometimes while working in certain programs you have to go through additional steps to preserve the EXIF. And finally, sometimes, depending on where you host the image file, the EXIF itself can be stripped there as well. Many of us use a bunch of different programs which may differ depending on what we're doing. We may do a RAW conversion from one program, some pixel editing in another, HDR in a third and skin softening in a 4th program. In a lot of these situations it would be a lot of extra work to ensure that the EXIF was intact for every photo for every conversion step from RAW to tif, to jpeg, png, etc. and most of us simply don't care if the EXIF is there or not. When I post a photo, I think about 1/3 to 1/2 may have EXIF. But if anyone wants to know details they are more than welcome to ask and I'll always be glad to answer and I'll just go back to my RAW file and look it up.

Aside from that, anything within EXIF can be edited if someone really wanted. So just because an image has EXIF data doesn't mean it is accurate. Being suspect of an image because there is no EXIF is just plain silly.


I am serious....and don't call me Shirley.

Thanks for the insight into the missing EXIF data. I hadn't thought of some of the things you brought up. Thanks for educating me.

There's also general latent metadata leaking concerns. There is a lot more in the EXIF data than aperture/shuterspeed/i​so.

A lot can be learned from your EXIF data, perhaps your location, information about your computer (including, in some cases login names), your real name. Basically the format allows for ANYTHING, and it's up to your camera and/or image editing program what to put in there.

If I start tracking your metadata over time, I can start tracking your habits. When you shoot, when you edit your images. If I can identify you as a person (which I probably can), I can find out where you live. If you upload images from the road, I can probably tell when you're travelling (using different computers, if the location data is removed). Of course, you also need to think about what kind of information your image content itself gives out.


I used to work in computer forensics. You'd be surprised as hell what can be discerned through metadata, whether EXIF or something like latent metadata in a Microsoft Word document.
