Hello @Edy154, and welcome to the forums. What happens if you use File > Open to open your second image? John

No problem with my Windows 10 PC box. John

The direct answer to your question is no. Raw files cannot be modified, and Affinity Photo does not save a sidecar file recording the changes applied during development. However, raw files are typically 12-bit. If you develop them they become 16-bit files by default unless you tell Photo otherwise (in the Document > Convert Format dialogue). If you then save the developed image as an .afphoto file or export to a 16-bit tiff, then you will retain the quality you are after. So, when you come back, if you load the .afphoto file, it will be as as it was when you saved it. John

Serif staff do not usually respond to explicit requests in this forum unless they are about to announce that your request has been granted, typically in a beta version. A single voice crying in the wilderness is unlikely to be acted on, but if others support your request then it is more likely to be acted on. Don't hold your breath though. John

You need to selact all the layers you want before applying the Live Stack Group. Having done that, select the mode you would like (mean median etc), then you can merge the group. An alternative workaround is to set the visibility for each layer before merging. For a stack of (say) ten layers: Set the visibility of the ninth (second from the bottom) layer to 50% (1/2), Set the visibility of the eight layer to 33% (1/3). Set the visibility of the seventh layer to 25% (1/4). Continue like this till you get to the top, then Set the visibility of the top layer to 11% (1/9). A merge visible will now give you the mean of each layer. John

Viveza 2 works OK on my Windows PC, so it could be a Mac problem. John

Hello @Mike_Doe, and welcome to the forums. Not sure what you men by 'order an avatar', but the following links may help: John

Are your ìmages linked or embedded? John

Looking at your layer stack, I would suggest that you apply Layer > Merge visible and then select this merged layer only for your Nik plugin. John

@paulreid1, it would help if you could post a screenshot of your layers panel. John

@trevorc, first you need to ungroup the layers in the stack. Then you should be able to align the individual layers manually. I do it by hiding all layers except the bottom two. Then I set the opacity of the second-to-the-bottom layer to 50% and align. Then do the same with the next layer up. John

Hello @jdadwilson, and welcome to the forums. Cropping is non-destructive. After cropping, apply Layer > Rasterise and Trim. John

No, but they have four sensors per pixel (RGGB). John

Or you could use the Refine Selection in the context toolbar. See here, for example. John

I always understood that was bits per pixel per channel. John

Hello @pjhvan, and welcome to the forums. You do not need to flatten before exporting to pdf. In fact it is better not to , so you retain the structure in your afpub file. John

You say a tiff saved from PhotoShop works OK. What file type were the files you loaded directly into Affinity Photo and how did you open them? John

The Nik 3 plugins work fine with Affinity. I can find no trace of a Nik 8 on DxO's website. Where have you got this from? John

I have been having a similar problem. I created an A4 threefold flyer in Serif Page Plus, but needed to revise it. I exported from PP to pdf and then opened this pdf in Affinity Publisher 1.9.1. I made my amendments and exported as pdf and sent it off to the printer. To my horror, all the images (a map and several photos) were all blurry. I discovered that the default resolution for rasterising images when exporting from publisher is 72ppi. Changing this to 300 on export generated sufficiently sharp images. I now have to get these printed again. The document setup gives the document resolution as 300ppi. Why does Publisher export with a default rasterisation of 72ppi? Can I change this? The olriginal PP document exported a pdf with adequately sharp images. I note that it did not give me any ppi option for rasterising. John

Hello @Ria Thomas, and wecome to the forums. Try going to Edit > Performance and switching off Hardware Acelleration. John

Hello @Sittatunga, and welcome to the forums. Try going to Edit > Performance and switching off Hardware Acelleration. I am intreagued by your User Name of Sittatunga, a long-toed African marsh antelope. John

I wold guess that this is due to the problem I identified above. Are there areas of sharpness available to the stitching algorithm? What overlap do you have between each image? John

Why not use Affinity Photo's Panorama tool? It will stitch an array of rows and columns. However, I can forsee a pronblem in that the Brenizer technique seems to utilize a shallow depth of field (to emphasize the bokeh). This will make it harder for the panorama stitching algorithm to find matching edges to merge. John
