microscopic quality pictures, the easy cheapo way?
This is specifically for people who have low
resolution and or non-zoom equipped cameras.
In this I will show you how to get extremely up
close pictures with a low resolution non zooming digital
camera using a magnifying glass. The camera being used
for this is an ?HP Photosmart 318?, it only has a max of
2.3 MP (Mega pixels) and no zoom. Cameras generally will
have stars or numbers indicating the quality of the pic
you want to take. The first two pictures where taken at
max resolution, with and with out magnification, the
deference is amazing.
Now you might be wondering, "What are you talking
about magnifying glass?"
Here is a
picture of the one that was used to take the second
picture, the macro of Jefferson's eye. This particular
type of magnification glass can usually be bought at any
textile or hobby shop. All you have to do is carefully
put it up to the agents lens of the camera. It will not
try to auto-focus since it seeing everything though the
?What if I already have a magnifying glass that size
but, it doesn?t have a flat backing and am worried about
it scratching my lens?"
easily solved buy taking a thick piece of card board and
using a spade bit, large hole punch, razor blade
basically anything that can cut or make a hole the size
you want. Make the hole the sized of the camera lens
then cut it out. THAT?S ALL YOU HAVE TO DO!!! The
magnifying glass will seat in that as well as center it
and space it far enough from the lens to avoid
scratching. If you suspect the magnifying glass still
might hit the lens just use a thinker piece of card
board or two pieces. Use double sided tape to hold it on
the lens housing, leaving your other hand free for the
?But what If I don?t have a magnifying glass will
any kind do??
No, you want to get a magnifying
glass about ? to " in sized or as big as your lens. If
it is really big (like the kind you would probably use
to look at your plants with) it makes it bulge-sum and
hard to get a clear over all picture.
In this picture you can clearly see the 0.5 MM
advantage of this particular type of magnifying glass is
the fact it has measurable increments . This can be
helpful for a number of resins, determining the size of
calyxes for indications of being ?seeded?,
guesstimateing the severity of a pest infestation buy
measuring the size of the pest to determine how long
they have been there and many other things where
measuring it?s size could be helpful.
down fall is that you need to have decent light. The
light from your grow light should be plenty.
"Can I use this same technique with hand held
absolutely, the only problem is if you don't have one
with a light equipped you will need lots of light
shinning directly on what you will be taking a picture
of (A double A MAG light works great as seen in the
picture). This particular one has 30x-40x-60x
magnification. You may have to take the picture at full
resolution if your camera has low MP's or if it's a low
powered microscope. I suggest an 80x or more if you want
pictures of individual trichomes.
A couple of tips for using this method.
Don?t use flash when doing this because of how
close you have to get. Flash will just bluer, distort or
make everything look white-ish.
If you have
?digital zoom? don?t use it, it will make the pic way to
big to cut and paste. You would have to compress the
picture buy stretch/skew-ing and the end result will be
about the same size anyway.
pic you can see the trichomes close enough to judge
harvest time with just 30x mag at 2 mega pixels with a
disposable digital camera cam. This is the easiest and
most inexpensive way I can think of to get good and
clear up close pictures with out special picture taking
equipment. This is perfect for pics of (female)
pistillates and (male) staminates pre-flowers,
trichomes, calyxes and small pests.

All these pictures where taken with
out the flash, I just used a cardboard box to steady my
self while I took the picture. It will take some
practice and a steady hand, before you can get good
