Advanced Photo Tips – SLR Camera

Post by Dave8472 » Mon Jun 11, 2012 10:35 am

Advanced Photo Tips – SLR

Hi all firstly this isn’t a guide to taking general pictures, cropping, uploading etc, there are some great threads already on the forum for that. However you may be able to utilise some of this for your set up.

This was requested by “Danish John” as he has just ordered a new camera, what you will need, SLR camera, approx 50mm lens, x10 magnifier lens, lighting ring, Paint shop Pro 5.

Set the camera level on a tripod and use a spirit level to check, in front of a window, not direct sunlight as this is too harsh. Mount a piece of glass or Perspex with a couple of inches of gap between the camera and a white sheet of paper, this stops shadows. Use “Manual “everything on the camera settings, and fit the x10 magnifying lens, if you haven’t got one you will have to focus from much further away. PS I sent you the link for the cheap magnifiers on Facebook, lighting ring also from same auction site, think that was about £30, anyone needs details of these bits PM me.

Image

Coins

Picture one shows the un-altered picture, aim for an exposure time of 1/100 sec, but with a tripod you can go lower, I also have a remote control to take the picture so can go much lower with no camera shake.

Image

Picture two shows the picture after a “Flood Fill” with white and “Brightness & Contrast “ adjustments, this will give your picture more definition and look less flat, the values will depend on the brightness variations of the daylight on the day.

Image

Picture three shows after the image has been “Gray Scaled”, you may think why on this coin ? but on some poor quality Silver coins that are very patchy it can improve the look of it, also I found after some time my collection on the web looked all different because of the varying lighting conditions, this uniformed all the images, on Silver artefacts I go one step future after this to alter the ”Gama Correction” and add a tiny bit of yellow back to the image to make it resemble the original item.

Image

Picture four is the cropped to shape and re sized to 300 pixels which is what I use on my web site, a little tip on all “*.JPG” images is they need not be lossy, when saving adjust the options, normal compression quality is 15%, I use 10% for mine but if you set at 1% it is really good, but off course file size is larger.

Image

Artefacts

Ok the problem here is depth of the item, if you used the above set up you will not get it in focus, although you can photo stack by taking more than one image at different focus and then use the draw program to cut them all together, I have done this but it is complicated. So take the x10 adaptor off and adjust the lens out to make a smaller image, this improves the focal range as picture five.

Image

Now second problem is a dark side and a bright side, in conjunction with the light I use a LED lighting ring on the camera as picture six. PS Don’t use the lighting ring on flat items like coins as it will knock all the depth out of the item and make them look very dull and boring.

Image

Repeat the same “Brightness & Contrast” adjustment and crop and you get picture seven.

Image

Hope this all makes sense John, by the way Paint Shop Pro 5 is all I use, it is old and cheap to buy, but all what I have done can be achieved in most draw programs, any questions let me know.

Great info. Might be worth adding that if you shoot in RAW mode instead of JPG (if your camera supports this, most decent SLR's do) you can edit the file a lot easier after the fact. It's like a digital 'negative' of your subject.

I used a poor choice of words there, thanks for pointing that out, I do have "RAW" on my camera but just use the best quality *.Jpg's I will edit that, thanks ::g

Thanks to the others for there comments ::g

Great post Dave

Just a quick word for anyone considering RAW files -

RAW files are not "better", however they can capture more potential detail, and the white balance (among other settings) can be fettled post-capture. A RAW file is not processed in-camera, and therefore will need processing (contrast, colour, sharpening and such) before converting to a printable or usable-on-net file (eg .jpg). Great if you've got the time, are shooting in difficult light, and/or are printing exhibition landscapes/portraits; the magazines are IMHO obsessed with making everyone use RAW. By all means, give it a try and see if it works for you but I reckon life's too short to peel a grape.

.jpg files are processed in-camera, and with a few subtle tweaks (such as in the original post above), can be perfect for web, or to store in a finds archive. They're also more than good enough for most peoples' photography. ;)

Thanks Pete, I did try a few RAW files when I first got the camera with the Canon software but not needed for my use, but thanks for the info on what you can do with it, I didn't know that, the camera can also store a dual file of both file types, but just use JPEG now ::g as I very much an amateur photographer :) outside I just you auto everything, apart form my moon shoots :D

IMHO the best way to take photos of coins and small things is to use DSLR+macro lens, at the moment I am using canon 100mm usm macro lens and very glad with results
if you need more zoom, you can also use macro rings (Kenko for example with auto focus) for capturing more details

This has been a very good thread as i have just bought a decent camera and was not sure on how to take some decent close up images,what happens if i am not able to use natural light from near a window can i use some form of external light without altering the natural colour of my images.

I have never perfected shots under just artificial light with a white background, it is probably possible with various different textured backgrounds, let me know if you crack it ::g

my photo was made with simple internal flash which is in camera, the coin was laying on phone leather black case, all colours can be edited with photoshop or adobe lightroom, which I am using and strongly recomend.
Adobe lightroom is better for begginers.

when capturing photo use tripod, because shaking hands can blur image(object)

Hi Mantas
That image is 100%. Your kit is 210% I do a lot of freelance photography using Cannon equipment, you probably use one anyway but a cable release is a good idea.
I sometimes use a copy stand with side lights,instead of the tripod would love a ring flash but to expensive.
You can also use extension bellows take a look at speed graphic website.

Thanks all, only change to this is I now use less natural light and more from the LED light. I also have a proper Macro Lens for the camera

Thanks Dave.. Lately we have developed really nice facebook group here... Photographing Artefacts and fossils..
Lots of LED light used in those photos.. -- I hope you will show witch one LED you use..
Also a lot of stacking used, specially if other things that a coin is photograpend.. stacking with 5 to 30 photos useing focus railing systemse.. Lots of experiments with LED and Light boxes.. Please share to inspire us.. -Thank you - John

Thanks John, I found this bell last week, c.19th century, I had to photo stack this, but it wasn't one of my better attempts, number two could have done 4 pictures for best effect

Yes Dave.. Specially on the photo from the top ( nr 2 photo) it can be spotted that the jump between exposure is to long. Also littel inside the bell. But still nice and clear photo.. Look forward to the LED instruction.. ::g
