Photoshop massive over zoom

Is there anyway to stop Photoshop zooming from say 400% to 12800%?? - Which is both annoying and ridiculous.

 

I think the problem is cause by a slight movement on the magnifying tool on a click and it uses that vector as a magnification level - even though I've got Flick Panning, Zoom with Scroll Wheel, animated Zoom, Zoom resises Window and Zoom clicked Point to Centre turned off.

 

Here's a cut-down animated gif of the video:

Yes, that's it. Dragging with the Zoom tool will zoom to the area where you drag, even if it is a small amount. This is by design and is not a Bug. I've moved your post to Disussions for now.

 

Click without dragging to control the zoom level. You might also consider the shortcuts of Ctrl + and Ctrl – if you have trouble keeping the mouse still.

I'm aware of zoom shortcuts, being a long time Photoshop user, me - but I have never experienced problems like this. Possible exacerbated by a lag delay.

Why, if this is by design, would you want to zoom into a single pixel at 32000% by default?

There's no scope for a lack of sensisitivity.

Dragging out the area to zoom into is fundamental Photoshop functionality, and always has been.

 

You need to hold the mouse still while clicking, or use the shortcuts.

By Ghoul Fool

 

The default is not zooming into a single pixel at 32000%.

 

It zooms to the area of the canvas that you drag across. Before we had scrubby zoom, it worked in a similar, but not the same way. When scrubby zoom is turned off in the options bar, you still drag the mouse, but you get a rectangular box showing you what you're going to zoom into and you can use the space bar shortcut to move the box to control where your zoom is going to be. Either way, dragging with the Zoom tool will zoom to the amount that you drag across. 

 

To see how it works, try, dragging across one of her eyes or both of her eyes or her entire face with the Zoom tool.

The one Zoom tool option you didn’t list is Scrubby Zoom.

 

I played around with it and found that the problem seems to be possible if Scrubby Zoom is disabled, because then zooming in Photoshop works in its old, original way (circa 1990): The zoom is set by the size of the rectangular region you drag. So if the input device accidentally drags across two pixels, Photoshop thinks you want to magnify two pixels to fill the screen, so it snaps to maximum magnification. 

 

The problem does not seem to happen if Scrubby Zoom is enabled, because with Scrubby Zoom, the farther you drag the more it magnifies, and it does it interactively. The only way to zoom a long way is to drag a long way. If the input device drags across just a few pixels, magnification will only increase by a percent or two. So, try having Scrubby Zoom on.

 

Because Scrubby Zoom is interactive (you can precisely zoom to any magnfication percentage in just one try), it’s a lot easier to control, so it is now the default zoom method in many modern graphics applications.

 

If you don’t see Scrubby Zoom in the options bar for the Zoom tool, make sure your GPU is enabled and working because I think it requires GPU acceleration.

 

Another potential solution: Some input devices, like some graphics tablets, have a threshold setting for drags. This is for if the device or operator can be a little twitchy and you want it to filter out micro-drags that might cause problems like this. 

 

The reason this is not considered a bug is because, as mentioned, many graphics apps worked this way in the beginning, some still do, and this problem hasn’t come up very often on forums going back over a third of a century. Because of the problem’s rarity, you probably won’t find a drag-zoom sensitivity option in any photo software (even by other companies) that still uses “drag a rectangle” magnification. It might be because typical mice are not prone to accidental micro-drags. As I mentioned, when a sensitivity option appeared it was in the software for other types of input devices such as graphics tablets, not in the photo applications. Which leads to the question, what type/model of input device are you using?

Scrubby zoom isn't listed in preferences, its in tools, which is why I missed it.

 

I've swiched it off because I tend to draw pixel art, which is made more complecated using a window at 1874% magnification - it's makes exactly pixel sizing visually difficult as opposed to increments of 100% ie (200%, 300%, 400%) - which I can gauge with precision.  Why? The pixels cease to be displayed as square (iknow they're not actually square) but a non-uniform gird of pixels at varying sizes is just a mess to work with.

 

 

I suspect the underlying cause is having an AMD processor - which has caused a host of frusrtations & Photoshop problems,  One of which, i suspect, is causing a micro lag switching between video cards. ( When I figure out the bios settings to switch the lesser one off, I'll get back to you)

As I'm using the same mouse and tablet as I've done for years with - same settings as old PC of which I had no problems drawing on.

Dual GPUs is always a potential problem, in lots of different ways. The general advice from Adobe is to disable the integrated GPU as per section 6 & 7 here:
