First attempt at focus stacking…

Standard

Had a bit of spare time so tried my hand at a bit of macro focus stacking on the flowers I bought my long suffering wife for our wedding anniversary..

Using a 100mm macro lens I got in close to one of the flower heads (don’t ask what it was… I just buy flowers based on what kinda looks nice lol)… even at f16 the depth of field is really shallow this close to the subject so the technique involves taking a number of shots focusing front to back in steps… I took 10 images in total…

You then do basic editing in Lightroom, select the images and then you can add them as layers to Photoshop by right clicking on the selected images…

Once in Photoshop you then go to Edit > Auto Align Layers (select Auto)… then Edit > Auto Blend Layers (select Stack)

This will process all the images (layers) by applying layer masks as required and blend all the focused areas of the layers together… once saved the final TIFF ends up in Lightroom for final editing..

Here is the result..

First attempt at focus stacking...

Happy with that… will try it on some other stuff soon πŸ™‚

Been a little while since I have posted so here we go πŸ™‚

Been playing with macro and the drip kit for most of the month, I also went to another race meet… so in no particular order here are a few select images from the month..

This image has been shortlisted to be in a photography magazine… not heard if it will be included but the recognition is welcome even if it doesn’t

Random post out the nowhere!

Standard

Been quite busy recently hence lack of updates so here is a biggish one…

I have had a week off work to clear up my office which quite frankly had turned into a tip…

Office Cleanup

Office Cleanup

No real excuse other than general laziness so felt it was about time I actually did something about it… so after removing 8 old PC’s, 4 old laptops, recycling no end of boxes and paper, 12 big bin bags of rubbish and what seemed like an eternity of paper shredding I got the ‘living’ space somewhere handy…

Well worth the effort although I do have a little more to do yet but I have at least broken the back of the job and the rest should be relatively easy to manage…

In other news I have been playing with electronics…. its been a fair few years since I have done any serious electronic project assembly but armed with a kit of parts I built a drip controller and trigger unit to do splash photography… I won’t bother going into detail as I’ll post links at the bottom with all the info but here are a few pics…

Drip controller…

Multi-trigger

Drip Kit

The multi trigger has essentially one output to trigger a flash so as I need the ability to trigger more than that I made a distribution ‘manifold’ to fire up to 5 flashes simultaneously… I do have wireless triggers but there is a small amount of lag in firing that can be tricky to dial out so this will alow the flashes to be triggered via PC Sync…

Drip Kit

Drip Kit

The setup is a little heath robinson at the moment while I refine it but it does work as you will see in a bit…
Drip Kit

The setup works like this… the drip controller can release up to three drips per triggered event and you control the size and time between drips to create different collision effects… the multi-trigger uses an optical interrupter to trigger a delay before firing the the flashes… the camera can be triggered from either control unit but I am using the splash controller as this seems to work best in dealing with the inherent shutter lag of a DSLR.

The flash guns are set to manual at a speed of 1/64 to be able to freeze the splashes with minimum motion blur.

Using a suitable tray full of water and a background of some description you fire the flashes at that to bounce light back to the splash…

In fairness its a little more involved than that but this isn’t a tutorial, there are plenty of those on the web and a fantastic e-book I got from Corrie White who does some amazing Liquid Drop Art (links at the end) which has great info in it…

So, spent a bit of time playing with the settings trying to dial the rig in… this took me a little bit of time and god knows how many images but here are a few of my initial results…

Finally a go at reflection…

Unfortunately the water was getting a little dusty at this point so not the best image but it was more to learn the technique than anything…

Pleased with the results and absolutely knackered from humping a ton of crap from the loft to the car and then to the recycling centre… I feel that this week I have single handedly saved the planet… and I didn’t have to wear sandals to do it either πŸ˜‰

More drip art very soon πŸ˜€

Fun with macro

Standard

I have had a macro lens for a while but haven’t really used it much… with the weather being a bit rubbish and the sun being too high at this time of year to make sun rise/set pics or astro pics realistic on a ‘school night’ I thought I’d dust it off…

I am not an insect person… not really keen on them at all and hate spiders in general… most macro photography seems to be insect related though which made finding inspiration a little difficult at first but thankfully there is a thread on POTN that is dedicated to none insect macro which is an interesting read.

Here are a couple of my initial shots…

This one was particularly tricky… working with a shallow DOF and a lively cat with manual focus…

This one needs some work on the technical aspect but the premice is to get a background object reflecting through the drop in sharp focus… the object in question was a box of Walkers crisps… nearly worked πŸ™‚

I then had a quick go at water drops… this is trickier than it looks…
Fun with macro

The water drops stuff really caught my interest and after a bit of reading up it seems there is some nifty kit available to facilitate this type of photography… most of it is relatively expensive, more money than I was prepared to spend just to take pics of splashes so I do what I normally do in situations like this and improvised πŸ™‚

Tried using a small plastic bag filled with water then pricked a hole in it using a needle… this worked ok and I used my intervolometer to take a series of shots…

The results were ok… there will inevitably be quite a few that you chuck away too of course

Changed the white balance in post to alter the colour of this one…

All seemed a bit hit and miss and also had a play with the camera settings a bit too… I then changed the configuration a bit and just used a bit of tube as a pipette and manually timed the shots… this proved a little more successful but was quite awkward non the less

So… next thing I want to try is to improve on the rig… I found the paint roller tray a little on the awkward side due to its shape, I think I will look into something a little shallower with less features that cast shadows etc as the step in the roller tray would sometimes cast a shadow in the pics…

I need a more hands off dripper system… the bag was ok but wasn’t flow rate or drop size controllable but it did at least land drops more or less in the same place… using a ‘pipette’ had better control but was a little inconsistent where the drop landed as I was holding it at different angles each time I was taking the shot, the changes were minute but in macro its enough to move the result well out of frame

I am going to try an irrigation dripper valve… these are cheap (Β£3 for three valves on eBay) so all I have to do is rig up a reservoir for the water and use a bit of silicon vacuum hose to plumb it all up… that should give me more controllable and consistent results (I hope)

Until next time πŸ™‚
