How to apply filters to a group in Photoshop?
I know how to apply filters to individual layers, but as soon as I organise the layers into groups, I can’t apply a filter to that group.
All help will be appreciated!
Thanks
This has happened to me one or two time, best is to save the file and re-open it. But if you click on the tool box and click on the arrow called the direction selection tool (A) that should do it. Then you can work will all layers. I personally save when I am about to add filters.

What are yellow filters for on binoculars?
I inherited some binoculars from my grandad. They came with some yellow glass filters that fit on to the end of the binoculars. As they don’t fit inside the binoculars’ carry case, I am assuming that he bought them separately.
So what are these yellow filters for? How do they help?
Human eyes are most sensitive to light in the yellow range.
They are also more sensitive to shades of light in that range.
The yellow filters take out the colors that the eyes don’t discern as well at low light levels so that they open up and get more of the yellow.
FYI: The gray scale cells in the eyes are even better in low light but are primarily around the edges and very sensitive to motion. If you are watching for meteors, watch slightly to the side of the area you expect them in and then shift your focus when you see the flash along the edge.

SE Electronics Reflexion Filter @ FrontEndAudio.com
The SE Reflexion Filter is basically a portable device for recording live sound sources with reduced room ambience. It is an advanced composite wall which is positioned behind any microphone by means of a variable position stand clamp assembly which ships with the product. The main function is to help obtain a ‘dry’ vocal or instrument recording. This is especially useful in studios without proper acoustic treatment, but can also be used to help record takes in control rooms, where the performer also has to operate the recording device, or in rehearsal studios to reduce ambient noise.
The SE Reflexion Filter has 6 main layers. Firstly, a strong layer of punched Aluminium which allows sound waves to pass through it, diffused, to a layer of absorptive wool. The sound waves then hit a layer of Aluminium foil which helps dissipate energy and break up the lower frequency wave-forms, and from here they hit an air space kept open by rods passing through the various layers. The air gap acts as an acoustic barrier. The sound waves then pass to a further layer of wool and then through an outer, punched, Aluminium wall which further serve to absorb then diffuse the remaining acoustic energy.
The main absorber has 4 formed pieces of state-of-the-art specialist acoustic absorptive material attached to its face via the extended separation rods, which further serve to absorb and then diffuse the sound waves as they pass to the main filter.
The stand assembly comprises a mic stand clamp fitting, which attaches by means of a vertical joint to the horizontal bar assembly onto which both the Reflexion Filter, and any standard fitting shock mount can be fixed. The microphone (in its shock mount) can then be moved both vertically and horizontally along the bar, and the Reflexion Filter itself can be moved vertically to obtain the optimum working position.
