You are correct, I misled you I am afraid. Optical wireless sync is possible with two external flashes (one on the hotshoe), but not via the built in flash.

I suggest radio triggers would give you more flexibility however

I seem to remember that is not possible optically with the K70. You would need radio triggers for that

Ah ok. I would expect them to solve that quite quickly. Thanks for checking.

If you go to Edit/Preferences and select the performance tab....

At the top it will show how much RAM you have and how much you are allowing PS to use. It will also tell you if your graphics processor is recognised.

I realise you have rolled back, but if you want to update again and post a screenshot of those settings it may help.

I run PS on a desktop with 16GB RAM and 22.3.1 works fine.

May not be relevant but only slot 1 will allow the update to work.

Use air only on your screen.

Love the greenhouse !

Our eye/brain co-ordination can show us images with detail far better than any camera sensor yet invented.

Your first image is by far the stronger, the second shows a washed out image.

You were right to use spot metering on the swan, to keep the image from blowing out, but remember spot metering on a white subject will still try and render it as grey. You need to overexpose either in-camera or in PP with a white metered subject. I think your spot meter placement was probably on an area of the swan that was in shaddow which is why you have rendered the white feathers correctly.

I too would use selective PP to bring out detail in the shadow areas of the birds feathers and leave the water exactly how it is.

Sounds to me that the camera is working properly.

If you take pictures in dark conditions you need to use high speed film or a wider aperture (or both). Increasing the shutter speed on its own to avoid camera shake will lead to under-exposed pictures.

Are you saying the shutter speed the camera selects is too slow ? If so your pictures will be overexposed.

A slow shutter speed by itself does not indicate a problem. When shooting in dark conditions you need to use a faster film ASA/ISO and a wider aperture on the lens to keep the shutter speed higher. Setting a higher ISO on the dial by itself will lead to underexposed film.

What lens are you using on the camera ?

I would first move the ISO dial around through all its movement while looking at the meter...does the exposure adjust correctly? Do the same for the exposure compensation dial. You can also check if the meter is functioning by testing it against a light meter and a uniform light source. If you don't have one, you can download an app for your phone which can replicate it quite well.
