Hello I'm Graham and I hope everyone's having a great day and welcome to this
video now in today's video we're going to look at some of the features of the
panasonic lumix after 80 or 82 camera that I discovered when I was writing the
users guide and I thought these might be of interest to you all so now you've
probably we're in the autofocus mode you can use the touchscreen
to position the focus point just exactly where you want it so that's a quick and
easy method of being able to set the focus point you can even use this with
the EVF so if you've got the camera up to your only then you can still use the
touchscreen with your thumb to position the focus exactly where you want so
you've got the best of both worlds now the first thing I want to look at today
is manual focus now manual focus is invoked by using the back control button
here which is marked AF AF macro and manual focus so if we push that in you
can see we can cycle between the three operations of alt focus the auto focus
macro and manual focus so once you've got manual focus set there press the
menu set button and the clue to the next operation is given by that just two
seconds worth of information there with the left hand navigation button if you
miss that then that was the key to being able to set manual focus miss it and you
probably don't know how to invoke manual focus so it started by pressing the left
hand navigation button which brings up the manual focus slide and the enlarged
view now you can set the area that you want to view for your manual focus so
you can get the critical focus by pressing the down arrow key and that
allows you to position the focus area but you want to check for focus exactly
where you need it so we're going to say select this character in the middle now
you can actually set the size of that area you can set it to the smallest air
if you want move it to the position you need either using the left hand the
right under navigation buttons or you can use your touchscreen when you've
done that press set and then that gives you the enlarged view when you're in the
enlarged view you can either use the sliders on the side of the screen here
so if you want to go to closer you move to the bottom further away you go to the
top so you can use those to change the focus point
and better if you use your finger it's a capacitive screen so you can actually
see the fact that we're changing the focus point and there are two speed so
you've got one speed and two speeds but I prefer to use the left and right
navigation button so I can cycle through the focus point just slightly through it
and then just tapping on the run time button to take me to the focus point
when I'm happy I've got the focus where exactly I need it just press menu set
and that takes you back to the screen ready to capture that image so can
capture that image that shot should be exactly in focus now another thing you
can do is if you're wildly out of focus so let's first of all set this wildly
over to focus so take it all the way to infinity come back to the shooting
screen you've got an area here which is the autofocus touchscreen so you can
actually use this as one touch focus to bring the area you've got under your
cursor to be in focus if I just press the AF button there you can see the
camera is automatically focused and if we press the left on navigation button
again you've got the enlarged view and you can see the cameras set focus for us
nicely so I can use that to set your manual focus if you got a situation
where the old focus is having difficulty in finding the right focus point perhaps
you're shooting through glass or you're trying to capture a bird in a tree and
there are fine branches in the way so either use the precise at area auto
focus or you can use manual focus in those tricky situations now there is
another focus in aid you capture use while you're in manual focus and that's
called focus peaking if you go into the custom setup menu on page four of nine
you can see I've got peaking set to on now you can actually set the color that
you want to show as the highlighted color so you've got a subject which is
green obviously you don't want to select a highlight which is green so I could
choose well under the yellow or the blue so in this instance we're going to
select the green area and we're going to set select the detect
level as high so it shows up the changes very quickly and if we just slightly
enlarge the focus area by just pressing the left-hand navigation button you can
see here on the belt of this character a little bit of green fuzziness so if we
change the focus point now you can see that that disappears when we hit the
focus point you get those green areas showing and that is showing you we have
the focus achieved at that point so focus peaking is a ideal way of being
able to capture your exact focus point now the second thing I want to consider
today is digital zoom now digital zoom is almost one of those areas that have
been highly debated as to whether they should use it or not and I think this
stems back to when cameras were first introduced with only two or three
megapixel sensors so if you try to use to do zoom with those very quickly you
started to see blow images or soft images because of the way the pixel
boundaries were met with these modern cameras with 20 or more megapixels I
don't see a reason why you can't use digital zoom providing music sparingly
up to say times one and a half times zoom equivalents well first of all
digital zoom will only work with a camera set up for a JPEG mode so if
you've got anything set with a RAW format such as I've got here raw and
JPEG you'll find that you can't turn on the digital zoom anyway so we're going
to select first of all the JPEG format and if we continue to cursor through
you'll find that the digital zoom is on page six but still it's disabled as you
can see it's disabled at that point but that's disabled because of another
setting that's not really explained and that's in their live view mode and live
view mode is in the setup screen on page two and by default the camera setup with
the economy 30 frames per second you've got to change that to either 30 frames
per second or 60 frames per second now 30 frames per second is ideal for normal
type operations if you use in sports and you wanted to get a smoother view then
use a 60 frames per second but 30 frames okay in my book so we're gonna select 30
frames per second and now if we come back to the record setup screen you
notice that digital zoom has now been enabled and we can go through and cursor
through and turn it on so once digital zoom is turned on it
does mean that we can start to use the camera with an expanded digital zoom
range so if you now notice when I assume the default of 1200 has now gone up to
4800 so it can actually use four times digital zoom but as I stated before it's
better to use this only up to say 2000 or 2400 at the very most which is the
two times little zoom you can actually still get some really good images well
here on screen now you can see an image that I shot at 1200 millimeters that's
the full optical range of the camera then I turned on digital zoom and shot
the next image with the focal and set to 2000 millimeter so I'll given something
like 0.8 magnification I would normally use it up to say 1600 or 1800 at the
most and that gives me at that point five times to zoom that I reckon is
about the limit that you want to push the camera to it gives her an extra
reach if you want to catch a bird in a tree if you're a wildlife photographer
or you just want to bring buildings closer if you're on travel or something
like that so it does give you that extra advantage possible a zoom is a better
option because of the way the camera works but if you just want to straight
forward digital zoom then there again try out to do zoom for your particular
needs now the third and final thing I want to cover today is the 4k post focus
now the post focus mode gives you the opportunity to capture a small mp4 video
file and from that you can actually select the frame which is the sharpest
in your sequence you can also use it to combine the range of images to give you
deeper depth of field so for example on this tabletop shot I've got all of these
Lego characters the distance from the first character to the last character is
about 18 inches so the camera can't the whole range in one focus operation
if I focus on about a third of the way into the image which is the possibly
this character here if I take that shot Pam we're at f4 point 5 which is the
sweet spot for the lens you can see on the screen that the last character is
out of focus so we haven't got enough depth of field between their first and
last character to get them all in one shot I can actually increase the
aperture to f/8 which is a minimum we will get again we're likely to suffer a
bit of image softening through diffraction limited resolution but can
Sam screen that last character is a little bit sharper but by using post
focus and then using focus stacking we can actually combine the images so we've
got one image has got the first character in sharpness another which has
got the middle one in and the final one which has got the last character in
sharpness to enable the post focus you either use the function one button or
you can use the drive mode dial so if you press the drive mode dial down then
select post focus when you press menu sets you can see we've cropped into the
image because you're using the 4k video mode which is given it gives you about a
1.4 times crop factor anyway so we've chopped into the image take that into
account when you're going to be shooting your image itself and now with the
camera setup it goes into the electronic shutter mode because we're going to be
filming in a video mode you can select the aperture you want span your ISO to
give you the right balance for the image exposure and then when you press the
shutter release button the camera will record all those 49 area points and make
a one-second video file so once the video has been captured you've given the
option either to manually arrange them all auto arrange them if you look on the
screen now you can see because we've got the peaking set you can see the first
character has got the green outline and that extends all the way through to
approximately this character here so if we let the camera arrange those
automatically we would see we've got a sharp first
but the last one is possibly how to focus so cus the menu set button and it
says do you want to save this image select yes and the camera will now save
that one image that we selected from the file if you want to move further through
the file we can use the left and right side navigation button and you can see
as I move forwards and backwards the focus peaking point changes so now
when we run the last character I press the menu set button I can save that
image and I can use those two images from that file to combine them myself in
an external imaging program like helican soft to give me a full range of images
which give me the maximum depth of field but hold the camera to do that we use
the auto range or manual range which is the function one button so when you
press function one it says you want to use your manual range or the camera will
select the range for you so first of all we will let the camera select that so
select Auto ranging press menu set and again unless you do you want to merge
those images into one jpg file so it will do that and create it in about six
or seven seconds
and now we can look at the image you use the zoom key so it can zoom in let's
have a look at the first character on the left hand side likes to be
unreasonable focus let's look at the character over on the right hand side
and you might notice on that character we've got a little bit of a distortion
the lines on the emblem on his coat a little bit Jaggi and there's a little
bit of artifacting around his arm so the camera hasn't really stacked those
together perfectly for us so let's go back and let us use the manual
processing mode so we'll capture that again you can actually use the playback
mode and use the same video if you wanted to but it's easier for me to just
rerun the video there but now we've kept that image file got into function button
one but this time we'll select range merging and though we highlight
on-screen the areas that we want to cover so I want to cover the first two
characters and I want to cover the last character so once that's done press menu
sets and yes to create an image again
again it takes about six seconds to create that jpg image from those files
but I suspect the result is going to be the same as the auto merge so again
using the zoom key war in the playback mode we can quickly look at the final
character
and again there's a little bit of artifacting on those images so this
character the vertical bandana shirt is distorted a little bit better on the
final character there's not as much chugging us on that final image so we'll
have a look at that full resolution on the screen and you can see how well it's
done it versus how the files that I combined using helican soft to combine
those images into one jpg file so that's the post focus processing method for you
I explained it in a lot more detail in my new user guide for this camera it
will be available on the Amazon bookstores from about the 15th of April
2019 or you can get as a PDF download from my store page on my photo blog
website so I'll put links to that in the video description below if you're
