Infrared on Portland (Dorset)

A few infrareds from a great day in Weymouth and Portland in superb sunny weather. All taken on using the Sony RX100 and R72 filter, post processed in DXO to tweak the contrast.

This cemetery has some of the best monuments in the area – and a great subject for IR against a clear blue sky with some high cloud to give some texture. These are two of the most impressive.

This is the first statue complete with broken wing from the rear – the bright dot in the sky is flare from the lens. The RX100 produces some very complex flare (see later article).

Finally a closer view of another monument. This camera produces very high IR quality images. better than my old IR digital camera, a Fuji F810.

Just Wandering Around…

A few more from the Sony RX100 – and no infrared at least for a short while. As the weather in the UK (Dorset at least) has suddenly broken, and after a cold spring, late spring/summer has finally arrived. The late summer has resulted in every plant bursting out in one go, flowers and pollen everywhere…

This first one is using’ the Toy Camera’ JPEG setting, plus a -1 exposure compensation to make sure the yellow colour channel isn’t blown out (the green/yellows of this camera are over saturated).

  This one uses the ‘Rich Tone Mono’ setting where three shots at different exposures are combined to extend the dynamic range. The whites of the flowers are a bit overexposed – my fault – but it’s a nice image.

  “Short while” over …. I couldn’t resist two more infra-reds – processed as per the last post. When you’ve got an IR R72 filter in your pocket and a sunny day on the heath – well what can you do?

_DSC0478

  This tree is ancient – growing on an old Roman road running from Badbury Rings to Salisbury and this is the first shot I’ve got of it which I’m happy with.

A Good Day for Infrared!

A few more from the Sony Rx100 plus R72 filter – on a very good day for infrared. All hand held at 800ISO 1/8th to 1/25th of a second at 28mm f1.8 +1.3 exposure compensation. The image stabilisation seems to work well most of the time even at these slow speeds. Shot in Raw at 20MP, then via DNG format and ACR to Photoshop and converted to B/W using one of the presets which seems to provide the best contrast.

_DSC0450s

This is the road to an old Dorset bridge near Sturminster Marshall (White Mill Bridge). The sky this morning was superb!

_DSC0458s

Here’s the Mill – taken from the same location as the lens tests earlier in the year. The vegetation has well and truly taken over and reflecting IR like crazy.

_DSC0455s

Slightly different view and a nice contrast between the bright greenery and the shadows.

_DSC0461s

Finally the bridge from the other side – the signpost is nice and sharp so all in all a good result.

If I can only leave the IR filter at home I’ll try to take some normal shots soon…..

Thanks for looking – hope you like them!

Five Hundred Shots (and Two Weeks) with a Sony RX100

I’ve been hunting around for a pocket camera which can produce commercial quality images for some time now, and I’ve finally found one which fits the bill. This mini-test describes some ‘first impressions’ after a few weeks.

_DSC0406

Good colour and exposure in macro mode – good start!

In order to be useful it needed to replace my old Canon G9 (which has done a brilliant job as a “carry everywhere” workhorse), be truly pocketable and have around 18-25 Mp resolution to prevent excessive image resizing to meet minimal agency requirements. It must also shoot RAW to give the widest flexibility in post processing….

DSC00007s

Unbelievably small!

Here’s another on a CD with the roll of 35mm film – it really is tiny!

DSC00006s

The lens is a 28-100mm equivalent, f1.8 to f4.9. f4.9 is slow for a 100mm lens – however my Canon 15-85mm zoom on the 60D is f5.6 at 85mm so it’s not that bad! In bright light, the 1/2000th of a second shutter isn’t fast enough for f1.8 at 28mm so a neutral density filter is needed if you want to get shallow depth of field effects (it can be held over the lens).

The physical controls are very configurable – I’ve assigned ISO to the rotating ring around the lens mount, and exposure compensation, image quality, DRO optimisation level, AF mode etc to the Fn button. In aperture priority mode the rear control dial varies the aperture, and it all works well. The camera keeps up well with frantic setting changes so no complaints.

20Mp image quality is very good with low noise to to ISO 800 – about the same normal working range I’d use on the 60D. The large sensor is obviously making a significant difference.

Sharpness at 28mm and f1.8 is a bit weak probably due to distortion correction, but cleans up by f2.5. At longer focal lengths its sharp enough across the frame for me.

_DSC0434s

Test shot in good light – colours tweaked from the default using an ACR colour profile (see later). 18mm, f5.6, 1/500th at ISO 100.

_DSC0434centre

Centre of the frame – the lens is sharp enough to pick out some telephone wires behind the tree which is impressive.

_DSC0434edge

Edge definition is fine too.

The Sony RAW converter is OK – but converting the ARW files to DNG format with Adobe’s RAW converter then using Adobe Camera RAW processing gives better results with more flexibility. Colour seems a little over saturated in RAW – especially a yellow hue to greens. ACR colour profiles by Maurizio Piraccini here allow for more neutrals results – and add a few colour options (thanks!).

Macro at 28mm and f1.8 is excellent, but the minimum focus distance increases dramatically as the focal length increases. The shallow depth of field at these close focus settings produces some good results – but it’s not a fast 50mm or 85mm on APSC or 35mm.

_DSC0337

Macro and some late bluebells .

_DSC0386

The last of the apple blossom. The slightly curved out of focus background highlights are like those produced by a Zuiko 50mm f1.4.

It reminds me most of a 35mm Minox camera which was a lovely small camera with a fixed sharp 35mm f2.8 lens. I really liked that camera – until it broke through overuse.

The special effects modes (JPEG only) aren’t bad, 10 frames per second is a bit over the top for me, but the multi frame dynamic range options and DRO settings look promising – I’ll do a test at a later date. All in all a very flexible package, and combined with an IR R72 and Neutral density filter (58mm diameter) a very portable one too.

Hope you find this useful and thanks for looking.
