I use a little DSLR gorilla pod and like it but one leg is really loose and moves too easily now. It's also really short so I can't get the right angles sometimes. I've stopped using flash since I like to make my mushroom pics look somewhat realistic and I don't know how to do that with flash

Turn the flash down really low like -1 so 75% of the light is from the sun, but the flash fills in the areas that are shaded.

I usually try to go for 50% flash and 50% sunlight in my pictures, but that varies a lot depending on shutter speed and how much sunlight there is.  Towards the end of the day, it's all flash.

I use a manfrotto carbon fiber tripod, it wasn't too expensive and I like it very well.  Tripods aren't all that good for the woods though, they tend to sink into the duff very slowly, making all your pictures blurry.  I can often do better handheld with flash and shorter exposure times.

Yea for sure.  Can be fixed in photoshop or the gimp with the clone tool though.  If cameras were made for mushroom photography the flash would be under the lens.




Absolutely, for my studio shots I have built a light that consists of a circular fluorescent tube which is of the daylight spectrum, it prevents any horrible shadows, I do a pre set white balance and the colours are almost perfect!
It is a cheap version of a ring flash but the light is constant.

Do you put the circular fluorescent around your lens like a ring flash?

It would be fun to adapt a bulb like that for field use with a battery and home made power converter circuit.

I would love to get that shoot out pack, but how do you collect mushrooms when your pack is tooled for a camera?

I have a satchel for my camera, two lenses and a set of tubes. It's not optimal.




You can re-order the compartments inside, it's enough to fit two cameras and three lens in with a drink and a few plastic collection containers (average local hunt is about 3-4 hours so it's not a big deal), there are two inside zipped pockets for storing whatever in (batteries, filters etc) then the outside of the bag has two compartments where I'm able to fit more containers in, I can manage one decent sized open container which I can use to carry back bigger mushrooms if I find any...

As for the ISO - I've always liked it a bit high but I've always prefered having a lower F number and hardly ever using the flash...I'm going to have to re-look at how I take pictures I think.

Also when taking pictures of mushrooms I like to focus on each bit separately (cap, stipe, etc) so I guess I never really needed higher F numbers though with a higher F number I could get all of the detail into one picture- makes more sense.

I'm looking forward to seeing how my new camera performs when taking pictures through my microscope, with my 1100D I usually take the pictures at either ISO 1600 or 3200. The 7D also has more megapixels which means more room to crop.

Quote:

There are lots of little tools you can use to make light work in your favour, a piece of foil for reflecting light up under the gills, a piece of dark card for throwing a shadow over a hot spot, a thin piece of white paper, like a receipt, for diffusing your flash.




Good ideas...

I found that today as well when using a tripod, it was quite muddy.

The last few days here have been dark and stormy so I've been without good light, the next few days are going to be the same so I'm going to use it as an opportunity to really test out low light conditions.

I took some pictures with my 1100D with the macro lens after getting home (outside when it was getting dark- the oysters are growing in a tub in my out-house, I dumped some woodchip mulch on card after it had stalled...):

[1/60 sec @ f / 4.0, ISO 800], [1/60 sec @ f / 4.0, ISO 800] [0.5 sec @ f / 20, ISO 800], [0.4 sec @ f / 20, ISO 800], [0.4 sec @ f / 20, ISO 800], [0.6 sec @ f / 20, ISO 800], [0.4 sec @ f / 20, ISO 800], [1/60 sec @ f / 4.0, ISO 800].

Yes, I hold it just in front of the lens, the tube is mounted on the original steel backing plate that comes with the light but I have cut the circular hole a bit larger so that it clears the lens, usually the ballast for the tube is also mounted on the steel backing plate but I've mounted it in a separate box with a small computer fan to keep it cool, some days I make a lot of collections and I may be doing my studio photography all night so the ballast needs to stay cool, I'm not an electrician and couldn't figure out how to power the fan with the same power source as the light so I improvised an old phone charger, it's not such a nice looking piece of equipment but I think it does it's job fairly well!

When I first started trying to design the light it was going to utilise led's that are in the form of a flexible strip that can be purchased at any length but I found the circular tube to be a simple alternative, maybe the led's could be good for a portable unit like you have mentioned?

Here is an example of the results from my light.

I love tripods and I basically only hunt forests.. all you have to do is push down and zoom to 10x to make sure nothing is moving in your shot.

How do you take most of your in-situ pictures inski? I aspire to take such realistic looking photos like almost all of yours are

I always use a tripod and remote shutter release, here's my set up!


I use manual mode and always use a fairly high f-stop, say between f22 and f32 depending on the depth of focus I require for the subject, the sharpest images are always at the lower end of those two numbers, I always use the built in flash at a setting of -3.0 and occasionally use a white piece of paper or similar in front of the flash to diffuse the light, the shutter speeds range between 2 and 15 seconds and I always seem to have to underexpose by 1 to 1 and a third EV, I also regularly use home made reflectors consisting of crumpled up foil glued to rigid card!
If you have a good macro lens and are using these high f-stop settings and are quite close to your subject you may not get the depth of focus you are after, the best way to remedy this is to just move your camera away from the subject slightly!
Hope that was helpful:)

Very helpful thank you! and nice setup! Where do you place the reflectors? I have never tried a long shutter speed with low flash setting, that sounds promising! and sort of obvious :doh: Only tried flash with really fast shutter speeds which means high flash and usually an unrealistic looking photo. Thank you again! I am going to try this out tomorrow

That's great, I'm glad it was helpful considering my state of mind at the moment:(

I usually use two reflectors in front of the camera just below the lens and facing the subject but at an angle of about 45° from both sides of the subject so light is directed from either side, the sun is my enemy so I prefer it when it is overcast, sometimes if it's sunny I'll have to create a shadow to block it usually with my back pack or myself or hands!

Here is the same collection as above in-situ.

Some more pictures this time also tested out with my microscope.

Pictures taken with a mixture of lens (including the EF-S 55-250mm) with my 1100D and 7D (I don't have the remote for my 7D yet so I'm still using my 1100D quite a bit).

I would like some IDs for these please...I have guesses but can't find them in my books for now...

Number 1 (Found growing in grass- length of biggest one = 8mm. Spores = 7 x 5):







Number 2 (Found growing in long grass- spore print in progess = White):



Number 3 (Found growing in grass- length = 2-3mm):



I may have mixed some of these pictures up with number one as I did them last night and they are on both of my memory cards...woops!





Somehow I seem to have measurements for three different sets of spores but only put two sets under the scope...I wrote a measurement for 4 x 3 down last night and also remember measuring spore at something like 13 x 7...probably shouldn't have done syndol before :smile:

2 could be Calocybe carnea.

Are you using a DSLR adapter for the micrographs?  If not you might want to consider getting one.  Some of the defects in your micrographs look like what I used to experience when I was using a large lens through the eyepiece.

You still have a bit of a harsh shadow, try using light from more directions. 

A light box would be good, or a light behind a white paper so the light is coming from many directions in a diffused way.

I was going more for composition and not worried about the shadow right now since it doesn't obscure any features. Thanks for the suggestions

This is the shot I took in the forest with flash yet still looks pretty realistic. Still not great but now I know how to use flash correctly! Thanks inski!



How much did you spend on your macro lens?

Which adapter would you suggest? What do I need to get?

I tested out my EF-S 55-250 IS II lens the other day, here's some of the results (didn't use a tripod)...



Some scene pictures- I was messing around with the camera but I liked the effect:



I didn't expect many of these pictures to come out well as the wood was so dark and I was in a lazy mood where I didn't use a tripod and just zoomed in on everything as far as I could (hence the wider aperture)...should have made more of an effort...

Looks like an eye!:



Xylaria polymorpha with something else growing on it:



My favourite picture from the day:



Some parasols:



Some moths (second picture is just a crop from the first):



Found here with some Marasmius oreades and Hygrocybe conica (and a bit further on a cup fungi):



I bought an LED ring light to try out with the camera and combined it with the macro lens (not for the spore pictures though):







I also used the ring light when I went out to take some pictures in some of my local woods...I put the camera in AV mode and forgot that I had it on ISO 1600 so some of the pictures are not as sharp as I would like:

I have this one and I am very happy with it.  The pics are nice and sharp and the construction is solid.  I don't have to edit all my micrographs with the gimp anymore to get good results.
