Default First Stacking Effort

Well of course you KNEW it was going to be a bug (look away Patty).

I started with 15 shots but realised that the spider had moved a fraction in a couple so cut them, and after also discarding those that didn't seem to add anything to the stack I ended up with just 6 to produce this. The spider is about the size of your little fingernail (a guy's not a girl's) ! Cropped out about 1/3. Some other PP.

K7 + Tamron 90 + Raynox 250 + Vebron Macro Rails on a Tripod. Ambient light. I forget exactly but I think it was full manual 1/13 sec / F11 / ISO 800.

All C&C more than welcome !

Thanks
Kevin

very nice shot! I love the DOF in this one. Very sharp, I thought my vivitar 135 macro would hold up to the vivitar 90 but it appears Im jokin myself with this evidence.

Are you using extension tubes?

Thanks NMR ! No just the 90 + Raynox this time. I'll try with the tubes next time and then both together. Baby steps for me starting out !

Focusing distance was about 4 to 5" with the lens fully retracted or 2 to 3" fully extended.

excellent, can you tell me how much of a crop, if any, this is from the actual size?

Im asking because;
My vivitar 135 can't get something this small in the frame such as this.
I was hoping by getting a dedicated macro i wouldnt have to employ extension tubes. Stil waiting on my extension tubes in mail. Looks like the Raynox is a pretty nice TC, as I see no signs of it here

Yesm I would love a shot with the tubes if you can next time just to see how the extension tubes 'stack up' against the raynox.

You are doing well for starting out. Im trying to begin dabbling in macro as well but looks like you're a few laps ahead

This is around 66% of the original (there was a lot of empty space behind and to the left of the spider). Each shot covered about a 1/4 of the spider in focus so 6 shots (with some overlapping) was just about right I guess (there wasn't much of him to cover) !

I'm interested to see how the 'tubes' compare too !

Some of the best macro shots I've ever seen employed a Raynox so they do seem to be great value for money with little IQ degradation.

Thanks but it's a long long road and I'm sure you'll catch up / pass me soon as I'm really not far down the road (just out of the front gate I imagine) !

ah jumping spider. they are very cool.
here's a stack of 68mm ET, and a 2x TC. around 4-5:1



be carful when stacking as you can damage things.
here's mister jumping spider with a reversed 50mm.



roy

think i'll set up my macro rig.

Hey there Roy, welcome back!
Was hoping you'd jump in here soon. a bunch of us are trying to enter the Macro realm.
I'm sure we can benefit from some of your experience.

FF. you did good on your first try! I still haven't tried stacking yet but, plan on it soon.

congrats to both of you on the jumping spider, the ones we have around here won't sit still long enough to get a quick close up let alone a stackable set!

Hi Kevin,

Very nice!

I'm a fan of jumping spiders, and hope to get opportunities to shoot some soon. These guys seem to be the most photogenic of the spiders with their big central eyes.

I doubt if I will be trying focus stacking soon, as I'm going to try handholding as much as possible -- at least for now. I can definitely see some of the advantages of a tripod though, and it's nice to see illustrations of the different techniques I can try with a such a setup.

I have an old Velbon Macro Rail (the steel one, not the newer Magnesium model), and it's very heavy. I found it at a garage sale for $20, and it has full rails in both directions, so it allows a whole lot of adjustment for position. I doubt that I'll use it because of the weight. A while ago, I bought a very rough Takumar bellows unit with plans to use the rail to make a semi DIY focusing rail. I got as far as taking it apart and discarding the trashed components, but ran out of steam there. If I decide to start using a tripod, I'll probably look into finishing this project first.

Very nice work!

Scott

Hi Roy,

Good to see you posting again. The last post I saw from you was a bit cryptic, and worrying. Hope to see some new pic posts from you soon. It's been too long. . . Hope things are going well for you now.

Scott

always hand held with no tripod or rail. if not using flash try a burst of 3-5 shots
