hey guys Harrison here and for the most part macro photography is about getting
close really close to your subject and there are two main ways that you can do
this so the first way is to use a dedicated macro lens on your camera just
like this one here and lenses like this let you focus very very close to your
subject allowing you to get in this case one to one magnification but some macro
lenses can go up to like five to one magnification pretty much letting you
fill the frame with even the tiniest of things the other way is to use a set of
macro or extension tubes just like the ones I've got here and what they can do
is essentially turn just an ordinary lens that you've got into a macro lens
that's actually not entirely true but I've got a whole video on extension
tubes that you can watch just by pressing it up there so if you're
interested check it out but then what happens if you've got a macro lens and a
set of extension tubes and then what happens if you don't only have one or
two extension tubes but you've got four extension tubes let's find out alright
so here we go I've switched over to my phone because I clearly need my camera
to take the photos with and so what I've done is I've just got my macro lens
on i've got the four extension tubes off just so you can see what it's like with
only a macro lens and then we'll slowly work out one by one until we've got all
four on and we'll just have to see what it's like
and so our subject for today is my Raspberry Pi we're gonna be focusing on
the logo right right here there's the Raspberry Pi logo so we're gonna see
just how big we can get it pretty much so you might also notice over here
it's bright it's way too overexposed that's because I've got this in the
sunlight because especially when we're getting this close trying to focus this
close to object you need a ton of light preferably just a flash would do - I don't
have any so we're just gonna use the sunlight instead by the way works
fine just make sure you've got enough light
because you're gonna need it with that said though let me get this set up and
we'll see what it looks like all right so just took our first photo which is
just with the macro lens focusing as close as it can to the subjects so
focusing at one-to-one and already it's looking
pretty big like we've gotten very close in already and now it's just time to
start any extension tubes I suppose and see just how macro we can go so that was
our first photo with extension tubes on as you can see it's just getting even
closer than before so I've got another one here and then I suppose we'll move on
to the other two all right there we go that was halfway there again it's just
getting closer and closer so let's get these other two on you know maybe we'll
just stick them both on at once I want to see what all four look like and I'm
gonna say it now so let's check them both on and see how it goes all right so
we've got all four on this is what it looks like it is a bit of a monstrosity
but hopefully it'll produce some pretty incredible photos before we do that I
just if you can look at this every extension tube hasn't fit perfectly into
the last and we're wobbling around quite a lot by the time we get a macro lens
which is just something to notice probably not the best idea having four extension
tubes on at once but we're gonna do it anyway
and just say what we can do first get this back on the tripod and see what we
can do
alright and that is what the Raspberry Pi logo looks like under some insane
levels of macro we had our macro lanes plus for macro extension tube slapped onto
the back of it that is 52 millimetres worth all the macros tubes on top of our
macro lens just insane levels of macro we can actually work out just how macro
we can get also known as the magnification by taking a photo of a
ruler we can see from this photo that we're getting about seven and a half
millimeters of the ruler in the frame and so if we divide the width of the
camera sensor by this measurement we can get the magnification ratio so if you do
19.3 which is the width of the Micro Four Thirds sensor divided by 7.5 you
end up getting two point five seven meaning a 2.57 magnification ratio and
now here are just some other pictures of the different components on the
Raspberry Pi at this crazy super macro size so those were just some other
photos of just the different components on the raspberry pi and it's just
almost silly like the depth of field that you get is just razor thin like less
than a millimeter I swear between in and out of focus just insane stuff and even
our magnification we were filling the frame we've got two LEDs one capacitor
was taking up the frame just crazy stuff but we can go one step further I've got
a pin here and let's just say how magnified we can get that so guys thanks
for watching I hope you enjoyed this just as much as I did and even if you
don't go this crazy I highly recommend you give macro photography a shot it's
pretty easy to get into it costs you know thirty or forty dollars to grab a
set of macro tubes and then you can just start taking crazy macro photos just
like we were doing although maybe not quite as a macro as we were getting
