PHOTOGRAPHIC THREADS: camera queries, any photo tech stuff!

The PS 'save for web' function is great and I use it as part of my standard 'Web Save' action set that I use to batch process all my images once I have them as jpgs.  Unless I'm mistaken, the PS 'save for web' function still needs to be part of an action set if you want to use it in batch or 'automate' mode.

Paddy will editing en masse allow you to crop out what you dont want?

I enjoy editing photos and have been siting for a long time editing those from the Fermi and Will trip

[Maggi Young]

I don't like to use an "edit all" function because I like to crop my photos to how I want them.
Ian is a much better photographer than I and can frame his photos better so is able to make use of a bulk  re-size for the Forum but I can't cope with that.... my pix need all the help they can get   

[Paddy Tobin]

Mark, I would edit photographs individually but after than would like to batch edit for size - reducing all to, say, 700 on the long size for websites.

This website gives very simple instructions for batch resizing photographs in Adobe Photoshop and is very easy to follow and turns a drudge of a job into a few clicks.

http://www.digital-photography-school.com/how-to-batch-resize-in-photoshop

Recommendation: In the dialogue window you are asked where you want the resized files saved. I find it best to save to the file from which they came. Photoshop will automatically create a sub-folder and save all the resized photographs there.

I recently bought a couple of adaptors that allow me to use my old lenses with my Canon EOS 500D.
One of these is an 18cm  Sonnar 2.8. Originally made in DDR I believe. This allows me to take "closeups" from a tripod in 2m distance meaning that I do not need to contort myself.
The lack of depth of field is of course noticeable but after some calculation I came to the result that f:11 would be optimal.
The problem in closing down the diafragm to smaller diameters is that the wave nature of light will blur the picture.
I show here two pictures taken immediately after each others. One using f:11 the other using f:32.
It is very clear how the depth of field is slightly improved in the f:32 but the sharpness is gone.
Hope this is of interest to someone:

I thought that I would try the batch resizing in Photoshop but it is not available in Photoshop 7 !  Back to the time consuming drudge again.

[Michael J Campbell]

Picasa will do batch resizing and transfer them to whatever photo software you use. It works for me with Adobe photo elements. Just highlight them,save them in the tray and then export to to your photo software. Picasa is free to download.

My Nikon Coolpix 8700 started behaving erratically last week. I had a customized programme set at aperture priority, unexpectedly the command button would not adjust the aperture settings. Next day in Custom 1 the focus button refused to work but the Lock button would focus. Then the same happened to Custom 2 shutter priority.  I was still able to photograph in Auto and Scene modes. Then the shutter button refused to work. Nikon replied with the usual instructions straight from the manual despite being told of the erratic behaviour.  Now they suggest I send it to Toronto for a free estimate.  Is this a common totentanz or can it be re-programmed or repaired at a reasonable price?

I have not dropped it into any flagons of ale or onto the greenhouse's cement floor.

John,
I will be of little help I'm sure, when I suggest that the majority of cameras have a 'return to factory settings' configuration.  I presume that Nikon also suggested this course of action?  Sometimes it proves necessary to try this procedure three or four times to override any electronic malfunctions (which may have been caused by all manner of unidentifiable events), though (by the sound of it) this is simply a faulty model!

On a different tack - may I thank you for introducing me to the wonderful word ... 'totentanz' , which perfectly describes my gait, general clumsiness and malfunctioning brain (and your unfortunate Nikon). 

... And 'Yes', I do realise it can mean 'dance of death'!!!   

[johnw]

Thanks Cliff.  Nikon had recommended doing a "Reset all" which I did quite a few times but to no avail. Once reset then it was impossible to get back to the necessary settings with the failure of functions and buttons.  The Coolpix is now Toronto bound to Nikon.

I know that gait as I often am so afflicted on rough terrain:

Nun hebt sich der Schenkel, nun wackelt das Bein,    Now waggles the leg, and now wriggles the thigh,
Gebärden da gibt es vertrackte;    As the troop with strange gestures advance, (Goethe from Totentanz)

I have  series of lenses going to waste in the attic - Canon and Sigma 50mm macro, 105mm macro, 28-70mm, 70-210mm, 75-300mm for my Canon EOS600 which I havent used in a long time.

If I buy a Canon DSLR body will these lenses work?

[Anthony Darby]

Yes, but not at the same focal lengths as with the film camera. My daughter has broken the screen on her camera. She needs a new one, but one with a rechargeable battery, not one that uses AA batteries, as these are unreliable. Based on experience of two cameras, they either lose their charge or the connections fail and the camera is therefore a liability.

What??  Not same focal length ??
Surely you men the distance from focus plane to lens mount??
Canon electronic cameras are slightly shorter than the older type. Thus you can use adapter rings. Simple ones will need manual focus and manual aperture control but I believe you can buy rings that give all the bells and whistles. I now use my old lenses with M-thread to my new camera and it works very well.

I had a Canon A95 which took AA cells, no problem, always thought AA cells where easy to get hold of. I did use the high capacity version of the AA batteries, last longer between charges.

On lenses. The size of the image sensor comes into play, so on the low cost Sony Alphas it is about 2/3 rd the size of a 35mm film frame, result is that a 200mm lens on film becomes equivalent to a 300mm one.

Lots of lens adapters on ebay, along with a market in lenses which will tell you how useful old lenses are.
