just "had" to post this big guy! tongue.gif...one of the biggest of the dragonflies and I haven't seen one of these for a couple years ...kinda rare ....wing span is over 4" and the body over 3"...they supposedly are immune to wasp venom and can even eat monarch butterflies....(usually nothing can eat monarch butterflies(toxicity thing) but this guy can)....I watched this one chasing various butterflies (apparently wasn't that hungary)..usually rests on rocks near streams and rivers.....just a little trivia grin.gifjonny

Nice shot, Jonny. I, too, was out shooting dragonflies today, and got some shots (bad background and light, couldn't choose it) of a dragonfly biting the head off a smaller dragonfly. They plopped to the ground right in front of me, all tangled up in death throes. I'm downloading now and will have to sort through about 3 Gb of shots before processing, but it's quite possible the killer I shot is a dragonhunter like this one. I'll post an image in behind you when I can get to it.

I had about 10 seconds to fire off all the shots I could get after the dragonflies plopped down to the ground. No time to put on a macro, and it all happened so fast, which is why the closeup isn't as sharp as it should be.

I didn't bother pulling full exif data. It was the Canon 20D, 100-400L IS at 400mm, at iso400 set to Av mode (aperature priority) and f8, handheld.

They crashed to the ground in front of me, a dragonhunter and its victim, a lake darner

A closeup of the dragonhunter beginning its decapitation. Is that panic in the darner's eyes?

Tom, I convert from camera RAW to Photoshop CS tiff, saving the image in that form. Then I convert dpi to 96 and size to about 600 to 650 pixels across for horizontals and 400 to 450 pixels across for verticals. Then I use Photoshop CS's "save for Web" feature, which forces the images to use as little memory as possible. They tend to look really nice if, when using that feature, they're saved at 75 percent. I'm not sure which part of this process erases the exif, but I'd bet it's one of the things that may happen with "save for Web," in order to save space. I always use this feature when posting on online forums because it's easier on bandwidth (and the forum owners, who have to pay for bandwidth, REALLY like small files), and a lot of forums have instituted strict file size rules I can't comply with unless using this feature.

I didn't bother posting my exif on this because it seemed the story was more important than the details, and I still had several hundred images from the day's shooting to sort through after posting these quickies. If it matters to you, I can easily go back and find that data. I shot RAW, which makes it quite easy.

Steve, By default, CS2 strips the EXIF when you use "save for web", but if you use "Save As", the EXIF remains. I usually "save" as a jpeg retaining EXIF data. I then use IrfanView to batch process to 800 X 600 or lower and upload to the web. Retains EXIF for those that care. Since I upload a couple of hundred shots per outing I find this method quick and fast. I just uploaded 250 baseball shots with conversion in no time at all. Just what works for me.

Oh and by the way nice photo series.

Thanks man. Good info. I figured it was the "save for Web" feature. But uploading 250 images to the Web at a time? Yikes! Better you than me.

Thats the nice thing about my service, I start the upload and walk away for about 20 mins or just start working on the next batch and it is done.

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      By Wanderer · Posted

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      Problems with Yetti

      By rundrave · Posted

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
