Magnolia: Minolta 50/f1.4

The Minolta 50mm f1.4 is one lens that every Sony Alpha and m43rds videographer should consider getting. Its cheap on eBay (its one of the most affordable f1.4 lenses on any system), and produces typical 1980’s Minolta color and bokeh, all with a wonderful depth of field wide open.

It suffers from the usual issues of 1980s glass (chromatic aberration and veil hazing wide open, less contrast than modern equivalents when wide open, chance of fungus). The chromatic aberration is easily removed in Lightroom (or is a non-issue at video resolutions), and the lens becomes very sharp from f2.8 onwards. Most issues have totally disappeared by the time you are above f3.5.

The less adventurous APS-C user would be better off with the cheap crop frame 50mm primes that Sony, Canon, Nikon and almost every other DSLR range offer (for Sony its the 50mm f1.8 DT) . Despite the issues of the Minolta f1.4 wide open, that’s exactly where I tend to use it as per the photographs above.

Loving how ‘advanced compact’ cameras are now good enough to make a handy stand-in for the DSLR. Not the same resolution, and not quite the same image quality, but small enough to carry all the time, and good enough to capture the photographer’s vision when the opportunity arises.

Painting with ice

Natural textures tend to be similar, so using ice textures to change a sky is not as odd as it might seem

Although Photoshop can now generate organic noise and texture, back in the day we had to use our own. Even now, I find photographing my own textures, and using them instead of synthetic textures is much better. One of my favorite sources is ice.

A few days ago, I was wandering about the garden with not much to do. I came across the wheelbarrow. Not much to look at…

It contained  leaves covered by iced water. I pulled out the ice to drain away the water and was about to walk away, when the sun came out. Never mind the mundane subject: I could only see the wonderful textures the light had suddenly created. I ran for my camera.

The photos here have not been re-colored in any way: I just waited until the side of the wheelbarrow was in full sun.

The photos have an ‘alien sunset’ feel to them. This is the sort of thing that comes in very useful in Photoshop, when you want to layer textures over an image to give it a more painterly or grungy effect. Using colored textures such as these, rather than just solid color filter values) is also useful when you want to add warmth or coolness to your photos.

Here’s what happens when I layer my alien sky over a simple and initially boring tree line.

I took some more photos…

Using a macro, I now zoomed into the ice surface.

All the images are taken with my 24MP Sony Alpha A77 at ISO 64. Looking at an actual size section above, you can see that there is zero noise, and lots of lovely organic texture (and as you can see, ice is rarely white: there’s every color of the rainbow there if you look close enough). Perfect source files for Photoshop layer effects!

Okay, onto an example of using our textures…

The photo on the left is as-shot. Looks nice, but for me it was missing something: the background is a little boring and dead. Layering in some ice texture in these areas lifts the final photo up considerably by adding movement, turning the final image into something much more organic.

Conclusion

Consider using your own textures rather than relying on Photoshop generated textures, except when you want pure noise. Natural textures tend to be similar, so using ice textures to change a sky (say) is not as odd as it might seem: both are natural fractals and therefore easier to blend into each other than (say) starting with synthetic Gaussian noise and trying to blend that into the sky.

Using your own photographed textures in Photoshop rather than using something like Instagram or Pixlr is preferable because the former (a) gives you a higher resolution final image, (b) you can create something more unique and personal to yourself because you are the sole content creator for the image and effect, and (c) with Instagram, any idiot who knows how to press a button can’t do just that and copy you!
