Hi, so here is my problem. Lightoom continuously exports photos that are less sharp, (the colors seem to match) but the sharpness is just consistently lower, and raising it to exaggeration in editing and exporting --- still doesn't do the trick. how this happens I don't know. at first i thought it was the interface of layout, that with its rectangular layout, what i was seeing on lightroom always looked sharper than the exported image. But i finally caught up that this was more than an illusion. so here is a photo to demonstrate how an exported image looks more degraded than the "edit". Why does this happen???? On the left you see lightroom finished edit. on the right is the image opened with macs photo viewer.= If you were to look closer you would see the eyes and mouth area are unsharpened in the right image (the exported). and the screenshot itself is of poor quality to show the telling difference. In case you are wondering. I am using lighroom 5 my image is previewed in lightroom using full quality in the settings. And upon export I do not choose the resize button. note: my concern is on the sharpness, not the color space. (does one affect the other, being that my monitor has never been calibrated.) Also, please stick to "easy fixes", if there are any, maybe a secondary plug in or a software to automatically calibrate this.
