In the comments, I was asked to take a shot from above. The days in London have largely been dull and overcast, but when the sun did come out I took the opportunity to take this shot.
Task completed.

This is taken from a Hi-res image (6775 x 4192 crop from a 9519 x 7314 original) with the camera set to ISO 200, lens aperture F8 at 0.6 seconds, resized to 1400 x 866 pixels (click on image to see full size). |
For the past few months my hobby focus has largely been on taking pictures with my new Olympus OMD EM5 Mark 2 micro four thirds camera. One of the reasons I chose the camera was because it features a 40 megapixel Hi-Res mode, which I thought was super awesome. It is, but after months of practice I've come to the conclusion that the really super awesome feature of my camera is the automatic focus bracketing feature, which was a firmware upgrade that the reviews I read didn't mention.
That's serendipity for you.
I've been sorting out some terrain and changing the graffiti I wrote on one of the building from FA*M Will Set You Free to Death Will Set you Free – driven by a friend who was playing in my old campaign who read FA*M as Football Association, rather than Freedom Army, which rather spoiled the effect that the graffiti was suppose to have for me.
The re-write involved sanding down the original letters to, to remove them, and then repainting the wall. As I didn't want to go to all of the effort it would require to repaint the wall to the original colour I took a short-cut and repainted it red.
I've been trying to do a real comparison of the advantages and disadvantages of using the Hi-Res mode of my camera, and the pictures in this post have been re-shot several times to get results I was happy with, and proving that I'm not as good as photographer as I like to think I am.

This is a 1027 x 1210 pixel crop from the 40 megapixel Hi-Res image. |
In some ways the results of this comparison are a little disappointing because the depth of field at F8 is insufficient to meet my needs, even thought the out of focus background is quite nice the lack of sharpness across the model is telling.

This is a 777 x 831 pixel crop from a 16 megapixel focus stack. |
Looking at the pixels, by taking a full size crop from each image, I think it's quite clear that the focus stack has produced the sharper looking image, and if I wanted to blur the background it would be possible to remove images from the stack to achieve the effect. So for now, until Olympus offer a firmware upgrade that allows automatic focus bracketing in Hi-Res mode, focus stacking 16 megapixel pictures is the way to go.

When I was out the other day with my partner shopping in the West End we happened to go in the Halls of Mammon, more commonly known as Selfridges department store. Initially this was to have a coffee break and use their facilities, but ended up in our wandering around for a bit looking at kitchen utensils when we found the photography department.
It impressed us.
Not the prices, as they were for the most part full retail, but because they had a pretty full selection of all the major brands on cameras: Nikon, Leica, Hasselblad, Sony, Canon, Fuji, Panasonic, Tamron lenses, Manfrotto tripods and Olympus cameras plus other things like accessories.
All in all a one stop shop for the photography enthusiast.
I of course was drawn the the Olympus section while my beloved nosed around the Nikon cameras and lenses. Afterwards we had quite a lengthy discussion on the various lenses we had seen; the Olympus ones in particular we had only seen pictures of on the internet. My question being around wide-angles and whether one should get a prime or a zoom. I quite fancy, as in I'm saving up for, the F2 20mm wide angle but I'm also very tempted by the 7-14mm F2.8 zoom that Olympus offer.
Today's post is a test of the assumptions we discussed on our walk.
Would a picture taken with a wide-angle zoom be of a good enough quality? Now I don't have the 7-14mm but I do have the 14-42mm pancake zoom that Olympus make. It's considered a kit lens: as in an all round cheap zoom, and I haven't seen a thorough review of it done by DXOMark, which is not that unsurprising really as by their standards it is cheap and cheerful.
I'll let you all be the judge but I have to say that I was surprised and impressed by the results.
The colours are slightly different because these were taken under artificial light and I obviously didn't adjust the pictures to match.
You can compare these with the shots I took with my 60mm macro here.
E-M5 Mark II with Olympus F2.8 60mm macro lens: ISO 200, 0.3 seconds at F8, 191.2mb RAW files processed using Silkypix +0.5 exposure, 25 HDR, 15 black – 8 picture stack processed in Helicon Focus and cropped to 8902 x 5021 179.3mb TIFF, saved as a 832kb JPEG using Graphic Converter.
And now, after much trial and error, some computer hang ups as my poor little Mac Mini struggled to process the files, the above picture is taken from a 40 megapixel stack made up from eight 191.2mb images. You can click on these to see them larger.
TIFF crop 39mb 3117 x 3106 pixels saved as a 809kb 900 x 871 JPEG using Graphic Converter.
TIFF crop 16.8mb 2279 x 2464 pixels saved as a 831kb 875 x 946 JPEG using Graphic Converter.
The 39mb image is so large that it's possible to take crops without loss of quality. Finally, just to show what an un-resized crop looks like.
TIFF crop 4.9mb 1192 x 903 pixel saved as a 889kb 1192 x 903 JPEG using Graphic Converter.
TIFF crop 4.9mb 1207 x 903 pixels saved as a 1mb 1207 x 903 JPEG using Graphic Converter.
I'm impressed.
I thought it might be useful to compare straight pictures taken by my Olympus OMD E-M5 Mark II versus those taken by my old Panasonic Lumix DMC GF-1. These three shots are full frame JPEGs from TIFF files saved off the original RAW files all saved to be the same file size. The difference in pixel count being down to the compression algorithm.
First up, my old Panasonic Lumix DMC GF-1 shooting a 4000 x 3000 picture, 12 megapixels. A 36.2mb RAW file was saved as 1mb JPEG, which produced a 1262 x 946 pixel picture.
Next my new Olympus OMD E-M5 Mark II shooting in the Hi-res mode 9612 x 6912, 40 megapixels. This results in a 191.2mb RAW file saved as 1mb JPEG, which produced a 1490 x 1117 pixel picture.

All the pictures were taken using my Olympus M. Zuiko F2.8 60mm macro
lens, which is the class leader for micro four third cameras. They were also taken on a tripod using cameras self timer to reduce camera shake.
The three shots were taken one after the other with the lens set at F8 using aperture priority. Both cameras were manually set to ISO 200, but the E-M5 Mk2 used a shutter speed of 0.4 (2/5ths) of second, while the DMC GF-1 used 0.25 (1/4) of a second. The difference in the shutter speeds could be down to either the light changing or the way the two cameras metering systems.
I hadn't thought to account for this, which is why I appreciate DP Review and DxOMark for there laboratory shots when they test cameras. It's harder than it looks to account for all the confounding variables and I certainly don't have the time and resources to match the professionals.
The next three shots below are crops taken from the TIFF files, which is what you get when you save process the RAW files into an image. The pictures below are as close as I can get to identical pixel size using my cropping tool.

OK as you can see the crop is rather cruel to the 40 megapixel shot. But if I crop the 12 megapixel shot to the same area and you click on the pictures you should be able see the real difference.

And that's it. Buy a great camera and make you models look like really rough. I will remind everyone that these miniatures are 28 mm tall.
